Shut Off Main Water Supply — Check Your Main Water Shutoff Valve
Part of project
Boost Low Water Pressure: A DIY Guide to Higher Home Water Flow · Step 1 of 3
In this video
Locate the main water shut-off valve for your house or unit, which is typically found near the water meter. Use an adjustable wrench to turn the valve to the off position, effectively cutting off the water supply to the entire building.
Goal: Stop water flow to the house
- Confirm you are turning the correct valve. In some areas, there may be separate valves for irrigation.

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.
