Common Water Supply Questions

Indicators include low water pressure, persistent leaks, discolored water, or inconsistent flow, suggesting damage, corrosion, or wear requiring professional evaluation.

The amount of time it takes to repipe a bathroom depends on how much piping needs to be replaced and how accessible the pipes are. Smaller, easily accessible jobs may only take a few hours, but projects that require drywall removal or removing old pipes or large clogs can take several days.

For the most part, choosing between 30/50 psi and 40/60 psi is based on your water-pressure preference. However, it can also depend a little bit on your house—if you have older plumbing, a lower water pressure can be easier on the pipes (and a bit more gentle on your well pump). 

The lower 30/50 pressure is usually enough for a single-story home, but you may want 40/60 if you have multiple stories, as the extra pressure helps water flow smoothly up to the second floor.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

A water hammer refers to the banging or knocking sound you hear in your water pipes after you turn off your faucet or when your washing machine or dishwater fills. This happens when highly pressurized water suddenly stops moving in your pipes due to a valve closing or your well pump shutting down quickly. Try adjusting the pressure setting on your water pressure tank—it should be below 50 psi (pounds per square inch). Or have a plumber install a water hammer arrestor.
