Inspect and Clean Main Hose Check Valve — Clean or Replace Showerheads and Faucet Aerators
Part of project
Boost Low Water Pressure: A DIY Guide to Higher Home Water Flow · Step 3 of 3
In this video
If the low flow issue persists after cleaning the spray head, or if the flow was weak from the hose itself, the clog is likely in the main hose check valve. Lift the large spring off the faucet spout. Unscrew the hose nut counter-clockwise to detach the hose from the faucet body. Look inside the end of the hose for the yellow check valve and flow restrictor. Use a flat-blade screwdriver to carefully hook and pull the valve out. Flush the valve with water from both the front and back to clear any debris. If the valve is damaged or cannot be cleaned, it can be replaced.
Goal: Clean the second check valve located in the hose
- The replacement part number for the hose check valve is 48224.

FAQs
What's the most critical first step before starting this project, and what safety precautions should I take?
The most critical first step is to locate and fully open your main water shutoff valve, as a partially closed valve is a common cause of low pressure. Before working on the PRV, know how to shut off your home's main water supply and have towels ready for potential leaks to prevent water damage.
What specific tools are essential for this project, and is the listed Wilkins PRV the only option?
You'll primarily need pliers and a multi-head screwdriver for cleaning aerators and adjusting/replacing the PRV. While a Wilkins 1 in. PRV is listed as an example material, you must verify the size and type compatible with your home's existing plumbing before purchasing a replacement.
I've cleaned all my showerheads and faucet aerators, but my water pressure is still low. What should I investigate next?
If cleaning aerators didn't resolve the issue, the next step is to focus on your home's Pressure Reducing Valve (PRV). First, reconfirm your main water shutoff valve is completely open. If the problem persists, your PRV might be faulty or set too low, requiring adjustment or replacement.
How can I safely and effectively adjust my home's Pressure Reducing Valve (PRV) without causing damage?
Locate the adjustment screw on your PRV (often on the bell-shaped top). Turn it clockwise slowly, making small adjustments like a quarter turn at a time, to increase pressure. Test the water pressure after each adjustment, avoiding overtightening, as excessive pressure can damage your plumbing fixtures and pipes.
