Sudden stop of water flow to all facets in house on a daily basis - no set time - just happens - pressure is fine - then all of a sudden water just stops flowing - be it the sinks, the shower, the washing machine etc. Then the flow comes back on its own within 20 -30 seconds - I have no idea how to even diagonosis this problem

Are you on city water or well?

Well

Do you have a pressure gauge on you tank? What does it read? Does the loss of pressure corespond to anything like the pump kicking in or does the pump kick in just before the pressure returns?

When I get home I will have to check - not sure... we have been in the house for 3 years now and this issue just started about 2-3 weeks ago -

The house itself is about 15-17 years old

Hi - thanks for the heads up re the gage on the pump - we just replaced the pressure valve and things are working fine again!

Glad we tracked it down. Come back anytime you need help or advice, sometimes we know what we are doing
