I'm totally perplexed. Suddenly my catchment pumping system is spitting air in the water piping system in my home. At first I thought it was the supply line from the tanks. Solid, no leaks and plenty of water in the tanks. So far I've changed out virtualy everything from:
1. The pump itself
2. The pressure tank
3. Entire outside plumbing from PVC piping, valves, check valve (coming from the supply line), filter canisters
4. Even installed a check valve on the cold water inlet to the hot water heater.
I'm wondering if my system is fully purged of air? The air is coming from somewhere. I thought it was the water heater so I installed a check valve. There is no leaks anywhere as the system stays pressurized overnight. But as soon as you turn on the water, air spits out despite the pressure tank fully filled with water, the water filters showing no signs of air in them (clear canisters). When you shut off the water, you can hear water dripping in the water lines as if there's no water in them.
Now when I shut off the cold water supply valve to the water heater, the problem goes away. Aha! so I think that's where the excess air is coming from! So I install the check valve on the cold water inlet and hot water outlet thinking that will solve the problem. Problem is worse now.
Am I not purging the system correctly? When I installed the new plumbing system, I primed the entire system from the pump outlet back to the supply line to the tanks. I cracked open the farthest cold water valve in the home and started the pump. Slowly the water filled the lines and the air stops spitting and the pump pressure hits 60PSIG and stops. I shut off the water valve and the pressure tank slowly repressurizes the plumbing system. The water filters show water draining into the water line in the house then it stops and begins to fill up as the pressure tank releases water pressure. The pump turns back on when the pressure drops to 40PSIG and shuts off at 60PSIG.
Now I'm thinking the system is fully purged of air and is correctly presurized to 60PSIG. I go inside and turn on the water and air spits out again!
1. Absolutely no water leaks before or after the pump system.
2. Totally new plumbing from the catchment tank to the water line going in the house.
3. Installed a water bib before the filters but after the pump. No air in the water as I open that bib.
4. Air seems to be introduced inside the house somewhere but no leaks.
5. I'm still suspecting the water heater as it's the only vessel in the pressurized system that could possibly hold that much air.
Help!
