Remove Old Pressure Reducing Valve — Disconnect Hoses from Shutoff Valves
Part of project
How to Replace Washing Machine Supply Hoses · Step 4 of 9
In this video
Position a bucket directly underneath the pressure reducing valve to catch any residual water. Using large wrenches, such as a pipe wrench or adjustable wrenches, loosen the union nuts connecting the valve to the pipes. Once the unions are loose, continue to use the wrenches to fully unthread and remove the old valve from the plumbing line. Be sure to hold the existing pipe fittings steady with a second wrench to prevent twisting or damaging the pipes.
Goal: Remove the faulty PRV
- Be prepared for water to drain from the pipes once the unions are loosened.
- Use a second wrench to counter-torque and prevent damage to the existing pipes and fittings.

FAQs
How difficult is it to replace washing machine hoses for a beginner, and how long does it typically take?
This is a beginner-friendly plumbing project, primarily involving disconnecting and reconnecting hoses. Most DIYers can complete it within 1 to 2 hours, assuming no unexpected issues. The cost is also low, mainly for the new hoses and some basic supplies.
What are the most important safety precautions I need to take before starting this project?
The absolute most crucial step is to completely shut off the water supply to the washing machine before disconnecting any hoses. Be prepared with buckets and towels to catch residual water and prevent water damage. Always use appropriate hand tools to avoid injury or damage to plumbing connections.
What are the most common mistakes beginners make when replacing washing machine hoses, and how can I avoid leaks?
A common mistake is overtightening, which can strip threads, or undertightening, leading to leaks. Always use new rubber washers with your new hoses, ensuring they are seated correctly in the fittings. After installation, slowly turn on the water and meticulously check all connection points for any drips or seepage.
How often should I replace my washing machine hoses, even if they aren't showing signs of wear?
It's generally recommended to replace standard rubber washing machine hoses every 3-5 years as a preventative measure. Hoses can degrade from the inside out, making them prone to bursting unexpectedly. Regularly inspect them for bulging, cracking, or stiffness.
