Measure the distance from your washing machine's water inlet valve to the wall supply valve, then add 6–12 inches of slack to avoid tension on the fittings. For reference: 1M (≈39.4" / ≈3.3 ft) typically works for machines positioned close to the wall, while 2M–3M suits setups where the machine sits farther from the supply. Always choose slightly longer rather than shorter to prevent stress on the connections.

This hose is designed with 1" and 2" threaded connectors — the two most common washing machine inlet valve sizes used in North American and international appliances. If you are unsure of your machine's fitting size, check the appliance manual or measure the thread diameter on the existing hose before ordering.

PVC extension hoses of this type are generally suitable for standard residential water pressure, typically in the range of 30–80 PSI. For exact pressure ratings specific to this product, please contact us to confirm compatibility with your installation before use in high-pressure lines.

PVC is generally resistant to moisture and mild environmental exposure, making it suitable for covered outdoor laundry areas or garages. Prolonged direct UV exposure can degrade PVC over time. For fully outdoor installations with direct sunlight, consider adding UV-protective wrapping or contact us for guidance on the best approach.

In most cases, yes. The 1" and 2" threaded connectors are compatible with the inlet valves found on the majority of top-load and front-load washing machines. Always verify your specific machine's inlet thread size before ordering to ensure a proper fit.

Hand-tighten the connectors first, then use a wrench for an additional quarter to half turn. Applying plumber's PTFE thread seal tape to the male threads before connecting is strongly recommended to ensure a watertight seal. Do not overtighten — excessive force can crack PVC fittings and cause leaks rather than prevent them.

If you have a single washing machine and only need to extend one supply line, 1 piece is generally sufficient. Purchase 2 pieces if you need to replace both the hot and cold water inlet hoses at the same time. The 3-piece option is ideal for households with two machines, or if you want to keep a spare on hand for future maintenance.
