Before we delve into the causes and solutions, let’s first understand what a shut off valve is and how it works. A shut off valve is a device that controls the flow of water in your plumbing system. It can be located near the water meter, at the main line entering your house, or at the supply line of a specific appliance. Shut off valves can be ball valves, gate valves, or globe valves, and they work by turning a handle or a wheel to open or close the valve.
Possible Causes of Water Dripping After Shut Off Valve
There are several possible causes of water dripping after the shut off valve, including a faulty shut off valve, a loose packing nut, or high water pressure.
A faulty shut off valve occurs when the valve is not fully closed, or is damaged. This can cause water to leak through the valve even when it’s supposed to be shut off. A loose packing nut can also cause the valve to leak, as the nut is responsible for compressing a seal around the valve stem. If it’s not tight enough, water can pass through. High water pressure can also prevent the shut off valve from closing completely, as the pressure is too strong for the valve to handle.
Troubleshooting Steps
To diagnose the issue, you can take the following steps:
- Check the shut off valve: Turn the valve handle or wheel as far as it will go, and see if it stops the water flow. If it doesn’t, the valve is faulty.
- Check the packing nut: Locate the packing nut below the valve handle, and use a wrench to tighten it. If the leak stops, the nut was loose.
- Check the water pressure: Use a water pressure gauge to measure the pressure in your plumbing system. If it’s above 80 PSI, it could be causing the valve to leak.
Fixing the Issue
Depending on the cause, there are different solutions to fix the issue. For a faulty shut off valve, you’ll need to replace it with a new one. This can be done by turning off the main water supply, removing the old valve, and installing a new one. If the packing nut was loose, you can tighten it with a wrench. To reduce water pressure, you can install a pressure regulator that will limit the pressure in your plumbing system.

How to install a Pressure Regulator to Reduce Water Pressure
Materials needed:
- Pressure regulator
- Wrench
- Teflon tape
- Pipe cutter
- Copper pipes
- Fittings
Instructions:
- Turn off the main water supply: Before you start, make sure to turn off the main water supply to your house. This will prevent water from flowing through the plumbing system and allow you to work on the pipes.
