I installed a bleeder valve on Southbound. This was just a “Tee” fitting, with a valve on the open end, inserted in line, just after the pressure
water pump. To bleed the water lines, you open the bleeder valve, and let the pump run until you get “airless” water.
Without a bleed valve, open up your
plumbing pipe/hose at the lowest practicable point, or the nearest faucet.
Then open faucets one at a time, starting at next nearest, and run till airless.
Typically, if you notice air in hot water lines
only, then it’s an issue with the water
heater.
