Let me first apologize, I didn’t intend to be argumentative. I do want assistance. I hate it when people are jerks on these forums, and that is not my intent. I just wanted to convey that my model had a short something in there. I guess I was worried because if it was made with it, I thought it had to be there. So since you say I will get proper water flow with just the pipe nipple, I accept that.
So I want to take you up on assistance with clearing what ever is obstructing my hot water flow. Here is what I have tried so far.
1. Removed and cleaned the aerators on the faucets.
2. Performed back flow on the hot water side at 3 faucets. This was done by opening the hot water at the washing machine, then at the water heater (1 at a time, not both)with drain open hose attached. Then plugging the aerator at faucet, and opening hot and cold. This forced cold water to back flow through the hot lines. I didn’t see any debris come out. Also flow was just medium.
I am now thinking I need to pull hot water valve stem or assembly and clean or replace. However please give me direction. Again so sorry for coming off badly.
