By turning on a tub or sink faucet to its highest level, you can effectively relieve pressure in the plumbing lines, guaranteeing a complete shut-down and minimizing potential damage. Additionally, opening faucets throughout the house allows the remaining water to drain down smoothly, reducing the risk of any lingering water causing issues. Therefore, leaving faucets open temporarily can be a wise practice to ensure a thorough and effective shutdown of your water system.

Is it OK to turn water off for a few days?

Yes, it is generally safe to turn off the water for a few days when going on vacation to prevent potential water damage. While regularly switching the water on and off can strain the pipes, shutting off the water supply for a short period does not pose any harm to the system. By doing so, you can minimize the risk of leaks or bursts in your absence and ensure the safety of your house from any potential water damage.

Why is water still running when main water is turned off?

When the main water is turned off but water is still running, it could indicate a malfunctioning meter shut-off valve. In this case, it is necessary to contact the water company or a licensed plumber to shut off the water flow at the curb. Once the curb shut-off has successfully stopped the flow, it may be prudent to replace the meter shut-off valve and potentially consider installing a pressure reducer if high water pressure is a concern. Properly addressing these issues will help ensure that water flow can be effectively controlled and regulated within the property.
