Fast cycling?
« on: January 16, 2022, 12:23:14 AM »
I have a CSV1A and 0.75hp pump.  It's been working perfectly for about 7 years now.

Recently I noticed the pump has been cycling every few seconds with the pressure flapping from low to high and not staying constant.

Is this indicative of a dead 4gallon pressure tank?  Or should I be looking at the CSV itself?  No changes have been made to the system.

Checked the air pressure and water came out, so I replaced the tank and all seems well.

Glad you got it working.  Usually cycling when no water is being used is a bad check valve on the pump.  Cycling while water is being used would be a problem with the CSV.
