Put in 770' of 1 1/2" pvc connecting 6" city water to my old cottage. Didn't flush the system. Just turned it on. My design is:
1 1/2" PVC> shut off valve > reduced to 3/4" PEX > water heater > exit WH via 3/4" PEX > reduced to 1/2" PEX > lavatory sink.
In and out lines to WH run 6" above WH. Initially I had some type of air lock and WH wouldn't fill. I put in a valve at the highest point of the incoming and bled the air. This worked and the WH filled. After it filled I turned the breaker on (it's an electric WH). I had the lavatory hot faucet open the entire time but still ended up with some type of air lock.
Now I'm afraid I've plugged my WH up with mud/sand from my piping install from the water main. I have two test valves at the highest point a few feet from the Attic mounted WH. I've got high pressure coming into the WH but nothing coming out.
If I crack open the WH pressure relief valve I get a dribble of hot water.
Any ideas? Is there a way to back flush a WH?
