Remove the P-Trap — Disconnect Old Hoses from Wall Supply Valves
Part of project
How to Replace Washing Machine Supply Hoses · Step 2 of 6
In this video
Using a pair of water pump pliers, also known as channel-lock pliers, loosen the two large slip-joint nuts that connect the P-trap. One nut connects to the sink's vertical tailpiece, and the other connects to the drain pipe going into the wall. Turn them counter-clockwise to loosen. Once they are broken free, you can typically finish unscrewing them by hand. As you loosen the final threads, carefully lower the P-trap, allowing the trapped water to drain into the bucket.
Goal: Disconnect P-Trap from drain lines
- The nuts only need to be loosened with the pliers. You can usually unscrew them the rest of the way by hand, which gives you better control.

FAQs
What's the most important safety precaution I need to take before starting this project?
The most critical safety step is to completely shut off both the water supply to the washing machine and its electrical power. Shutting off the water prevents flooding, while disconnecting power protects you from electrical shock, especially if there's any water spillage during the process.
Do I need specific tools, or can I use an adjustable wrench for the hose connections?
While an adjustable wrench can work, tongue and groove pliers (like Channellock) are highly recommended. They provide a much better grip on the hose connections and nuts, reducing the chance of stripping or slipping, especially in awkward spaces behind the machine. Make sure to use two pliers – one to hold the valve steady and one to turn the hose fitting – to prevent damaging the water supply valves.
What type of washing machine hoses should I buy to prevent future leaks or bursts?
Always choose braided stainless steel washing machine hoses. Unlike rubber hoses which can degrade and burst over time, braided stainless steel offers superior durability and resistance to kinking and pressure, significantly reducing the risk of a catastrophic leak. Ensure they come with new rubber washers for a proper seal.
How tight should I connect the new hoses to ensure they don't leak without overtightening them?
Connect the hoses hand-tight first, then use your pliers to tighten them an additional quarter to half a turn. Overtightening can strip threads or damage the rubber washer, leading to leaks. The goal is a snug fit that compresses the washer just enough to create a watertight seal.
