I turned off main water valve into the house so I could replace 2 valves in the kitchen. Now that I have turned the water back on the water pressure is low after every toilet flush or if you wash your hands or turn on more than one faucet at the same time. What can I do to get water pressure back to normal?

Hi TH

I hate to ask, but I must; is the main water shutoff opened all the way? Check by closing and then reopening fully.

Next, I would need to know if you are on city/town water or are on a well system?

If you are on city/town water, is there a pressure regulating valve (PRV)... see image? If so, it could be clogged up and need to be cleaned.

Check these things and post back with more info... see what we can think of here, OK?
