I. Compatibility & Fitment
Q: Will DECA's high-pressure hoses/stubby guns work with my pressure washer?
A: Our accessories are engineered with industry-standard connections, including M22 threaded fittings, as well as 1/4"and 3/8" quick-connects. As long as your pressure washer does not feature a proprietary, non-detachable hose setup, our parts will provide a perfect upgrade for almost any machine.
If you have an electric pressure washer (e.g., Ryobi, Greenworks, Sun Joe): You will primarily need to verify the inner diameter of your M22 fitting (14mm vs. 15mm).
If you have a gas-powered pressure washer (e.g., Simpson, Honda-powered units): These typically utilize 3/8" quick-connects or standard M22-14mm twist connections, allowing you to connect DECA's heavy-duty steel-braided hoses directly.
Q: What is the difference between M22 14mm and M22 15mm? How can I check mine?
A: This is the most common point of confusion with pressure washer fittings. While the exterior threads of M22-14mm and M22-15mm are identical, the difference lies in the diameter of the internal center pin.
M22 14mm: The most widely adopted standard across the industry.
M22 15mm: Typically found on Sun Joe, Campbell Hausfeld, and certain AR Blue Clean machines.
The DECA Advantage: If you are purchasing our 3200 PSI high-pressure hose, it features a universal design that effortlessly fits both 14mm and 15mm pins, meaning you can skip the measuring process entirely!
For our other accessories: Forcing a 14mm fitting into a 15mm pump outlet will either fail to seat completely or cause immediate leaking. If you are unsure and buying our other attachments, use a digital caliper to measure the thickness of the center pin on your machine's water outlet, or simply snap a clear photo and send it to DECA customer support for an instant identification.
Q: Can I connect your accessories to a standard garden hose or a regular household faucet?
A: Absolutely not. Standard garden hoses and household water supplies run at a low pressure of around 40–60 PSI. DECA's steel-braided hoses, stubby guns, and foam cannons are industrial-grade accessories engineered to handle extreme pressures ranging from 3200 PSI up to 5000 PSI. Our fittings are incompatible with standard 3/4” GHT (Garden Hose Thread) connections and must be installed downstream of a dedicated pressure washer pump.
Q: My pressure washer has quick-connect outlets. Can I plug a DECA hose straight into it?
A: Some entry-level residential machines (like certain Karcher or AR Blue Clean models) utilize proprietary click-in or push-button connections rather than standard M22 threads. DECA hoses come standard with M22 threads or 3/8" quick-connects on both ends. If your machine features a proprietary connection, you will need a "brand-to-M22" adapter first, or you can opt to upgrade your entire line setup with a full DECA system. Feel free to send a photo of your machine's outlet to our support team if you need help finding the right adapter.
Q: Why did my 1/4" nozzle tip shoot off as soon as I pulled the trigger on my DECA stubby gun?
A: This happens when the 1/4" quick-connect collar is not fully engaged and locked. When inserting a nozzle tip, make sure to pull back the outer sleeve of the brass quick-connect, push the nozzle tip firmly all the way in, and then release the sleeve until you hear a distinct, positive "click." Before turning on your machine, always give the nozzle tip a firm tug to ensure it is locked securely in place. This prevents the high pressure from turning the tip into a projectile.
II. Product Specifications
Q: What are the maximum pressure (PSI) and temperature ratings for DECA hoses and stubby guns?
A: Our core product lines are built from the ground up to handle demanding residential and commercial-grade tasks:
Working Pressure: Rated securely for machines operating anywhere from 3200 PSI up to 5000 PSI.
Burst Pressure: Our steel-braided hoses are engineered with a burst rating far exceeding their working pressure for ultimate safety.
Temperature Rating: Safe for warm-water operations up to 140°F (60°C), making them ideal for cutting through heavy grease, road grime, and stubborn oil stains when paired with compatible warm-water setups.
Q: Why does DECA only sell accessories instead of the actual pressure washer machines?
A: We realized that most stock accessories included with factory pressure washers—especially entry-level plastic hoses and long, unwieldy wands—are often made cheap to cut costs. They kink constantly, feel stiff, and leak prematurely. DECA’s philosophy is "Upgrade Without Compromise." We focus exclusively on crafting premium attachments using top-tier materials like stainless steel quick-connects, abrasion-resistant TPU covers, and high-density, single-wire steel braiding. We allow you to unlock professional-grade detailing and washing efficiency without forcing you to buy an expensive new machine.
Q: What makes a steel-braided hose better than a standard factory plastic (PVC) hose?
A:True Kink-Free Performance: Factory PVC hoses are stiff and retain a frustrating "coil memory" that leads to constant tangling. DECA hoses feature a high-tensile steel-braided core wrapped in a flexible outer jacket, giving them excellent flexibility—they pull straight instantly.
Heavy-Duty Abrasion Resistance: The internal steel layer provides rigid structural integrity, allowing the hose to be dragged across rough concrete, asphalt, and driveways without wearing thin or bursting.
Extended Lifespan: DECA steel-braided hoses typically last 3 to 5 times longer than cheap residential plastic hoses
Q: Does the DECA stubby gun feature a swivel? What is the benefit?
A: Yes, our premium stubby spray guns feature a heavy-duty, built-in Live Swivel crafted from high-grade brass and stainless steel. This is a game-changer for car detailing and power washing. It allows the gun to rotate a full 360° freely while the hose remains completely straight underneath. This eliminates the headache of your high-pressure hose twisting, coiling, and binding up as you walk around a vehicle, drastically reducing user fatigue.
Q: Does a 3200 PSI to 5000 PSI rating mean a DECA accessory will boost the pressure of my small machine?
A: No. The PSI rating on our accessories (e.g., 4000 PSI) indicates the maximum safe working pressure limit that the component can handle; it does not increase the pressure output of your pump. If you connect a DECA gun and hose to a 2000 PSI electric washer, your actual output will remain 2000 PSI. However, our premium fittings will ensure smoother water flow, minimal pressure drop, and exceptional durability compared to stock parts.
III. Usage & Maintenance
Q: Why is my foam cannon producing thin, watery suds instead of thick, "shaving cream" foam?
A: Thick foam relies on the perfect balance of three variables: your soap concentration, machine flow rate (GPM), and the internal orifice size.
First, ensure you are using a dedicated, high-yield foam shampoo and diluting it according to the manufacturer's recommendation.
Second, check your pressure washer's GPM. If you are using a compact electric washer pushing less than 1.8 GPM, replace the pre-installed 1.25mm orifice inside your foam cannon with the bonus 1.1mm orifice nozzle included in your DECA package. Lowering the orifice size restricts water flow slightly to create higher velocity, allowing lower-GPM machines to pull more air and throw incredibly thick, satisfying foam blankets.
Q: Are there any special maintenance steps after using my DECA gun and hose?
A:Relieve Post-Shutdown Pressure: After turning off your pressure washer and shutting off the water spigot, always squeeze the stubby gun trigger one final time to bleed out the residual high pressure trapped in the line. This relieves stress on your internal rubber O-rings, prevents premature wear, and makes disconnecting your quick-connect fittings effortless.
Avoid Prolonged UV Exposure: While our outer jackets are built with UV-resistant compounds, leaving any gear exposed to harsh, direct sunlight for extended periods will accelerate material aging. Store your gear in a shaded spot or garage when not in use.
Flush Clean After Chemical Use: If you have been running aggressive soaps or hard water, we highly recommend flushing your foam cannon and gun line with clean, fresh water for 60 seconds before packing them away. This prevents dried soap buildup and mineral scale from clogging the internal mesh agitator.
Q: I noticed a tiny leak/drip coming from my high-pressure connections. How do I fix it?
A: Over 90% of high-pressure leaks are caused by a worn, dry, or slightly unseated rubber O-ring.
First, inspect the internal O-ring at the connection point to see if it is cracked or missing.
If a threaded connection is weeping slightly, wrap the male threads tightly with 5 to 8 wraps of the Teflon Tape (thread sealant tape) included in your DECA box, then tighten securely with a wrench. DECA includes extra replacement O-rings in every package so you always have spares on hand.
Q: Can I run harsh chemicals like weed killers or bleach through my DECA hose and gun?
A: We strongly advise against running highly corrosive chemicals—such as high-concentration sodium hypochlorite (raw bleach)—directly through the internal components of your high-pressure hose and gun. If your job requires applying bleach (such as downstream washing a house exterior), make sure to flush the entire system with clean water for 2 to 3 minutes immediately after completing the job to neutralize any chemical residue and protect the internal seals from degrading.
IV. Orders & Shipping
Q: Where do you ship from, and how long will it take to receive my order?
A: All orders for the U.S. market are fulfilled directly from our domestic U.S. warehouses. Once your order is placed and confirmed, our team packs and hands it over to local carriers (such as USPS, FedEx, or UPS) within 1–2 business days. Standard domestic shipping typically delivers your package right to your door within 3 to 5 business days.
Q: What should I do if I order the wrong size or find out it doesn't fit my machine?
A: Don't stress at all! We offer a 30-day hassle-free return and exchange policy. If you run into any compatibility or installation snags, please do not force the fittings together. Simply snap a quick photo or record a short video clip of the issue and send it to our DECA customer support team. Our technical experts will diagnose the problem right away. If you just need a small adapter to bridge the gap, we will often ship you the required fitting free of charge. If it is completely incompatible, we will provide quick instructions for a streamlined return or exchange.
Q: What happens if my tracking says "Delivered" but I can't find my package?
A: This happens occasionally with domestic carriers. Often, a driver will place a package in a discreet location to prevent theft (such as behind a bush or side gate), or a neighbor might have accepted it by mistake. We recommend checking around your property first. If your package is still missing after 24 hours, please contact the carrier to open an investigation and notify DECA support. We will gladly assist you with the claims process or look into a replacement solution based on the situation.
Q: I bought a full bundle kit (Hose + Gun + Foam Cannon). Can I return just one component I don't need?
A: Our curated product bundles are offered as a single unit to give you the deepest possible discount. If you find that a specific component in the bundle does not fit your workflow and you wish to return it separately, please reach out to our support team. We will evaluate your request and offer a partial refund solution or guide you through swapping it out for a compatible accessory.
