Signs that your shower valve has gone bad include a variety of issues with water flow and temperature. Common symptoms are low water pressure, inconsistent water temperature, and dripping or leaking from the handle or showerhead when the water is off. You might also notice that the knob is difficult to turn or won't turn at all. Another key indicator of a bad diverter valve is water coming from both the tub spout and the showerhead simultaneously, or being unable to switch the water flow between the two fixtures. In advanced cases, the water may not turn on at all. These are all signs that the valve may need to be replaced.

You can buy a sealant spray for a leaking copper pipe, but it’s not a permanent solution and isn’t usually a good idea. For the best adhesion, you should drain the pipe, let it dry completely, apply the spray, and wait for it to dry before turning the water back on. Even with proper technique, a sealant spray is a temporary fix, so you should only use this technique in the interim to prevent water damage if you’re waiting for a more permanent fix.

No, a larger well pressure tank will not increase your home's water pressure by itself. Water pressure is determined by the pressure control switch on the well pump.

However, a larger tank does offer other benefits. It can store more water, which allows you to run water for longer periods before the pump needs to turn on. This reduces how often the pump cycles on and off, leading to less wear and tear on the pump and the entire well system. Consequently, a larger tank can help extend the life of your equipment and may prevent future pump issues that could affect water pressure.

If your goal is to increase water pressure, consider these alternatives:

• Adjust the pressure settings on your tank to a higher PSI (pounds per square inch).

• Replace your current pump with a model that has a higher flow rate, measured in gallons per minute (GPM).

• Have a professional install a water pressure booster pump in your plumbing system.

• If you experience pressure fluctuations, consider upgrading to a constant pressure system.

Yes, you can technically use a utility knife or straight blade to cut through PEX pipe. However, this isn't an ideal method simply because you won't get the same clean cut that you'll get with a pipe cutter. A utility knife will likely create angles that weaken your push connections. If you use a utility knife, score the pipe with the knife along your marked line several times before making your final cut.
