Lawn and Garden — FAQ
What's the difference between a garden hose nozzle and a pressure washer nozzle?
Garden hose nozzles operate at household water pressure (40-80 PSI) and connect to standard 3/4-inch hose threads. Pressure washer nozzles handle 1,500-4,000 PSI and use 1/4-inch quick-connect fittings. Never interchange them—using a garden hose nozzle on a pressure washer causes catastrophic failure and injury risk.
How many spray patterns do I actually need?
For general home use, 4-7 patterns cover all tasks: jet for cleaning, shower for plants, mist for seedlings, and flat for rinsing. Casual gardeners can manage with 3-4 patterns, while serious detailers and landscapers benefit from 7+ specialized options. Single-pattern nozzles excel only for dedicated applications like misting systems.
Are metal spray nozzles worth the extra cost?
Metal nozzles last 5-10 years versus 1-2 seasons for plastic. They withstand drops, UV damage, and high pressure without cracking. The upfront cost doubles but eliminates annual replacements, making them cheaper long-term for regular users. Occasional users can save with quality plastic models.
Can I use hot water with these spray nozzles?
Most metal nozzles handle water up to 140°F safely. Plastic nozzles typically max out at 100°F before warping. Pressure washer nozzles withstand higher temperatures due to stainless steel construction. Always check manufacturer specifications—thermal damage voids warranties and creates leak hazards.
Why does my spray nozzle leak at the hose connection?
Leaks stem from worn rubber washers, cross-threaded connections, or incompatible thread types. Replace the washer annually and hand-tighten only—wrenches crack nozzle housings. For persistent leaks, apply plumber's tape to threads. Verify you're using 3/4-inch GHT threading standard on garden hoses.
What's the best spray nozzle for washing cars without damaging paint?
Choose a nozzle with a gentle 'shower' or 'fan' pattern delivering wide, soft water distribution. The RESTMO or FANHAO metal nozzles provide excellent control. Avoid narrow jet patterns that concentrate pressure. Keep the nozzle 12-18 inches from the surface and use the flow control dial to reduce pressure on delicate areas.
