Frequently Asked Questions
All fittings add some restriction. Use the smallest number of adapters and pick a coupler size that supports your machines GPM (e.g., 3/822 for many hoses; 1/222 on higher-flow rigs). Keep components clean to minimize losses.
The O-ring may be flattened, cut, or missing, or debris may be trapped in the socket. Replace the O-ring, clean the socket, and confirm youre using the correct plug size and thread type.
Yes, but be mindful of galvanic corrosion in wet or salty environments. If exposure is frequent, consider matching stainless-to-stainless components.
FKM is often selected for higher temperatures and better resistance to oils. Verify the couplers overall pressure and temperature ratings against your washer before use.
EPDM is commonly chosen around sodium hypochlorite and other strong alkalis. Avoid NBR and FKM in these mixes. Always confirm compatibility for your exact chemical strength and temperature.
NPT is a 606 tapered American pipe thread that seals with thread interference and sealant. BSP comes in parallel (BSPP) and tapered (BSPT) forms with a 556 profile. They are not interchangeablealways match the thread family your equipment uses.
Measure the plugs outside diameter (or the sockets mouth) with calipers and compare to the nominal size used in your system. Also check the threaded end for its size and thread family (NPT or BSP). If youre unsure, bring a known mating part to match.
Use your washer’s GPM and target operating pressure to select a starting orifice from a nozzle chart, then test and adjust one size at a time on your rig.
Reach depends on your machine’s GPM/PSI, nozzle size, spray angle, and wind. Adjustable and original long‑range nozzles can often apply solution to second‑story eaves from the ground on contractor‑grade machines.
Both are external‑injection long‑range nozzles. The Original offers fixed long/close patterns and typically maximizes reach; the M5 lets you twist from narrow to wide for fast pattern changes.
A nozzle designed to project water or detergent farther than standard tips, using a narrow spray angle and correctly sized orifice to maintain stream integrity over distance.
A small hose‑washer screen is not a substitute for a full‑size inline strainer. Use the inline strainer for primary protection; the washer screen can serve as a coarse backup at the faucet connection.
Bowl filters make visual inspection easy; Y‑strainers usually provide more screen surface area for higher‑flow systems. Choose based on service preference, available space, and pump flow.
Many strainers are rated for cold or warm water. Always confirm the temperature rating of the body and bowl. If your inlet water is hot, locate the filter where temperatures are within its limits.
A properly sized strainer with adequate screen area and the right mesh will protect components while maintaining flow. Undersized housings or clogged screens can restrict inlet flow, so size generously and service as needed.
A 60–80 mesh screen is a common starting point for municipal or tank‑fed water. If you find fine particles on the screen or experience nozzle plugging, move to a finer mesh; if restriction becomes an issue, step coarser or increase screen area.
Install the strainer on the low‑pressure inlet side of the pump, oriented with the flow arrow in the correct direction and placed where you can easily inspect and clean the screen.
Only if the generator is sized for that motor’s starting and running watts. Electric motors can need several times their running watts at startup; confirm specs before attempting.
Match the cord to your load and distance. Heavier loads or longer runs typically use 12 AWG or 10 AWG outdoor-rated cords to limit voltage drop and heat.
Inverters are quieter and provide cleaner power for electronics. Open-frame commercial units deliver more watts per dollar for motors and heaters. Pick based on total load and sensitivity of devices.
If you plan to run equipment that requires 240V now or later, pick a 120/240V model. Many burners and controls are 120V, but mixed accessories or expansion may justify 240V.
List every device you’ll run at once, convert each label to watts (volts × amps), add likely startup surges for motors, then add 20–30% headroom. Choose 120V-only or 120/240V based on your outlet needs.
Inspect periodically for debris, scale, and seal wear. Service intervals depend on water quality and usage hours rather than a fixed calendar schedule.
Yes. A float switch can control a solenoid valve or a feed pump. Ensure electrical components are correctly rated and installed per applicable codes.
A properly sized valve should maintain tank level during peak demand. Undersized valves, clogged screens, or low supply pressure can limit refill and allow the level to drop too far.
Mechanical arm-and-float valves use a lever to open/close the seat, while diaphragm-style valves use internal pressure and a diaphragm for compact, low-splash shutoff. Both regulate level when sized correctly.
Some polymer valves are intended for cold or warm water only. Always confirm the product’s temperature rating; for hotter water, choose a valve with materials rated for the application.
Check the tank’s bulkhead or the removed valve for the thread type and size (commonly NPT) and match male/female orientation. Avoid reducers that create a bottleneck on the inlet line.
It opens to refill the tank as the level drops and closes at a preset height, helping prevent pump starvation and overflow during operation.
Heat often improves efficiency, but effective cleaning is still possible with dwell time and agitation. Follow product directions and jobsite constraints.
Keep a steady walking speed, overlap passes, and maintain even nozzle height. Rinse uniformly after cleaning.
Avoid strong caustics and strong solvents that may soften asphalt binders. Choose mild cleaners and rinse promptly.
They can react with certain aggregates, colorants, or sealers. Pre-wet, spot test in a hidden area, and use the mildest effective solution.
Use an alkaline degreaser for petroleum-based soils and an acidic product for mineral deposits or rust. Always test first and follow the label for dilution and dwell.
There is no universal interval. Inspect based on water quality and usage, and clean when debris is visible or performance declines.
Use chemical-compatible materials and dedicated pickup filters for injectors to avoid cross-contamination. Rinse or replace screens that contact chemicals per your process.
All screens add some restriction. Finer mesh and dirty screens increase pressure drop. Oversizing the housing and cleaning the screen as needed helps maintain performance.
Select a housing rated at or above your system flow and with enough screen area to keep pressure drop low. If you need finer mesh, consider upsizing the body to maintain flow.
Follow your equipment manufacturer’s guidance first. As general ranges, coarse 20–50 mesh is typical for tank draw/foot valves, 50–100 mesh is common for inlet protection on relatively clean sources, and 100–200 mesh is often used to protect small orifices. Always confirm the filter’s flow capacity to avoid excessive restriction.
Place an inlet filter on the water supply line before the pump. High-pressure inline filters, when used, go downstream of the pump to protect accessories and nozzles.
Yes. Check for a clogged or torn screen, an air leak at the barb or clamp, or a strainer that isn’t fully submerged. Correct these before replacing the injector.
It’s helpful for long or vertical runs. A foot valve holds prime and reduces air ingestion between bucket changes or when lines are elevated.
It can. Finer screens add restriction, which may lower draw on small‑orifice injectors. Choose the coarsest mesh that still protects your system.
A soap strainer is a pickup filter that sits in your chemical container. A Y‑strainer is an inline screen installed on a supply or detergent line for higher flow protection.
Rinse after each bleach or acid use, inspect weekly in heavy service, and replace at the first sign of tearing, collapse, or scale that won’t clear.
Strong oxidizers attack many metals. Favor plastics (polypropylene, PVC) or 316 stainless screens. Avoid plain steel and bare brass in long‑term bleach exposure.
There isn’t a universal standard. Many setups work well between 40–80 mesh—start mid‑range and adjust based on draw rate and debris load. Always confirm your injector’s recommendation.
Add your machine’s weight, fluids, and any mounted accessories, then choose a cart or wagon with a rating that comfortably exceeds that total. Never exceed the product’s stated capacity.
Pneumatic wheels cushion bumps and roll easily on rough ground, but require air and can puncture. Flat‑free wheels avoid downtime and suit shops and paved areas, with a slightly firmer ride.
Two‑wheel carts tilt back on a pair of wheels for compact maneuvering and tight spaces. Four‑wheel wagons keep all wheels on the ground for greater stability and easier rolling over distance on flat surfaces.
Inspect the pump coupler, blower wheel set screw, and wiring terminals. Replace worn couplers and re‑balance or clean the wheel to avoid vibration.
Some PSC motors ship with a matched capacitor; others require purchasing the specified value separately. Use only the rating listed by the motor manufacturer.
Only if the frame, flange and bolt pattern match your burner. Even small frame differences can misalign the blower wheel or oil pump coupler.
Match the nameplate RPM on your original unit. Many AC burner motors run about 3450 RPM, but verify your label—do not assume a universal speed.
No. Voltage and power type must match your system. Substituting DC for AC (or vice versa) requires matched controls and wiring, which are different parts.
Check the arrow on the motor nameplate or the burner manual and always reference rotation as viewed from the shaft end. If unsure, mark fan blade direction before removal and match it.
Both are control interlocks. A pressure switch reacts to pressure at a port; a flow switch reacts to water movement. Many washers use either design, but you should replace like‑for‑like to match the wiring and control logic.
It serves as a safety interlock for the burner. When system pressure indicates you are actively spraying, the switch enables the burner. When the trigger is released and pressure/flow changes, the circuit is interrupted so the burner shuts off.
Install the correct cleaning tip, pull the trigger, then adjust the unloader while watching the gauge. Verify that any brief spike on trigger release stays within the machine’s limits.
They are recommended anywhere pulsation causes pointer flutter. A snubber or small needle valve ahead of the gauge smooths pulses and can extend gauge life.
Larger dials (2.5–4.5 inches) are easier to read from a distance. Use smaller dials only where space is tight and you can still view the pointer safely.
Functionally they read the same. Pick the mount that matches your port location and gives a clear view while you adjust the unloader or test pressure.
Use liquid‑filled gauges when pump pulsation or vibration makes the pointer hard to read. Choose dry gauges where vibration is low or where a wider ambient temperature range is expected—confirm the product’s rating.
Select a full‑scale range that comfortably covers normal operation, with additional headroom for spikes. Many technicians choose a range up to about twice typical working pressure for readability and margin.
For setup and general diagnostics, place the gauge at the pump outlet or on the unloader’s gauge port. To measure line loss, move a test gauge to the hose‑to‑gun connection.
Some pumps route the drain through a different cover location or require a brand‑specific adapter. Provide your model and we’ll advise compatible options.
Long enough to reach a safe pour point outside the frame without sharp bends or contact with hot surfaces. Many techs choose a length that reaches beyond the skid rail.
Tighten to the torque value in your pump manual. Over‑tightening can crack a rear cover or distort sealing surfaces.
Yes—select hose, seals, and valve components with temperature ratings suitable for your unit’s operating environment.
Check your pump’s model data sheet or manual for the crankcase drain port specification. If you can’t confirm, contact us with the pump model and we’ll match a kit.
It replaces or extends the factory drain plug so you can route crankcase oil to a convenient location for clean, controlled changes—reducing mess and service time.
Avoid mixing technologies on the same run. Different loads can create uneven brightness and dimming behavior—use matched products from end to end.
Many pro sets use rectifiers to reduce visible flicker and are compatible with select dimmers. Check the product’s specifications for dimming and rectification details.
It depends on bulb wattage, run length, and wire gauge. Add up the total load and keep the circuit comfortably within capacity. Use a GFCI-protected outdoor receptacle and consult a qualified electrician for onsite specifics.
12-inch spacing is the classic look. Go 6-inch for tighter, brighter outlines or 18-inch when viewing distances are long or rooflines are tall.
Both commonly use 18 AWG conductors; SPT-2 simply has a thicker jacket. Pick based on environment and component fit, and always match plugs and sockets to the wire’s SPT rating.
C7 strands use E12 (smaller) sockets and pair with C7 bulbs for finer detail; C9 strands use E17 (larger) sockets that read brighter at a distance—ideal for bold roofline outlines.
Do a bucket test: time how long it takes to fill a 5‑gallon bucket fully open. Divide 5 gallons by the seconds/60 to estimate GPM and compare to your washer’s rating.
Yes—if the pump is rated for gravity/tank feed. Use large, smooth‑radius plumbing (often 3/4 in. or larger) and a clean inlet strainer; avoid air leaks on the suction side.
Use modular sections long enough to span the target edge without gaps. Connectors or end‑to‑end contact should create a continuous seal; shorter sections make tight turns easier on irregular surfaces.
Oil‑only and universal absorbent booms are generally treated as single‑use once saturated. Manage and dispose of spent sorbents according to local regulations and the nature of the absorbed material.
Most containment booms are not designed for vehicle traffic. If you need vehicle access across a controlled area, plan a designated crossing using drive‑over containment solutions and route traffic around booms.
Periodically check for leaks at the ports and stem, flush after chemical use, and replace the valve if it drips when fully closed.
Yes—if the valve is rated for the temperature. Check the product spec; seat materials often set the limit.
No. They are different standards and will not reliably seal together. Use the correct thread type or a purpose‑made adapter.
Common placements are near the pump outlet, at the hose connection, or on a short whip near the gun. Place it so you can isolate and safely depressurize before disconnecting anything, and keep a bypass path open via the unloader.
Brass or plated valves are economical for mid‑pressure and moderate temperatures. Stainless valves are preferred for higher pressures, hotter water, and improved corrosion resistance. Always confirm the product’s ratings.
No. Use a ball valve only for on/off isolation. Rely on the unloader and proper nozzles for pressure and flow control.
3/8 in. ports with NPT threads are most common because they match many pro hoses, guns, and unloaders. Some high‑flow systems use 1/2 in. for lower restriction—verify what your plumbing uses before ordering.
Many brass swivels are suitable for hot water within their stated ratings. Always check the specific model’s temperature limit and seal material, and match them to your application.
A 90° turn can add minor restriction. Use straight bodies where maximum flow is critical, and 90° bodies where routing and clearance are more important.
Replace the swivel if it leaks from the body or weep hole, binds during rotation, or shows corrosion or damage. Rebuild kits may exist, but replacement is often faster and more reliable.
Inspect regularly and replace when worn, cut, or leaking. There is no universal interval—environment, heat, and chemical exposure drive service frequency.
Each component carries its own manufacturer warranty. Keep proof of purchase and install per instructions; misuse or operation beyond ratings may void coverage.
Yes, if pressure, flow, temperature, and connection types match. Verify nozzle/orifice sizing for injectors and tips so you maintain proper operating pressure.
Some do, many do not. It is best practice to have PTFE tape and/or a suitable thread sealant on hand for tapered threads. Do not apply tape to quick‑connect couplers.
Use detergents compatible with the listed materials and seals. Verify chemical compatibility and always rinse equipment with fresh water after use. Avoid acids or solvents unless a kit specifically states compatibility.
Some kits are hot‑water rated and others are not. Confirm the maximum temperature listed on the kit or component pages and match it to your application before purchase.
Check your machine’s PSI and GPM, water temperature, and connection sizes (quick-connect and thread types). If those match the kit specifications, compatibility is likely. When in doubt, contact us with your model details.
Wide‑fan, low‑impact patterns help spread solution evenly and minimize intrusion. Choose sizes that keep delivery low pressure at your target flow and test before full application.
