Hot water heater problem
Helping a family member work on their TT. They have little to no water flow through the hot water tank. I've checked all the obvious and pretty sure a check valve is stuck but not sure where it is l...

Led 67, this TT was recently purchased so I don't know any background on the unit other than it doesn't have a anode rod because someone installed an electric Hot Rod kit in it.
C-Leigh Racing, if I recall correctly they are metal shafts on the valves and both feel normal when opening/closing them. When the bypass is open, the water is bypassing the heater and is cold at the taps.
The next trip out I am going to disconnect the hot side and allow water to flow into a bucket to check and see if I have good flow coming out of the heater. Hopefully this will narrow it down between the right angle fitting and the shut off valve.
Ok, I see what your saying, so the bypass when open, is just letting the water flow past instead of going into the water heater & then back out. That how it should be.
Next thing, those two on & off valves, you can take the screw out of that handle, pull it off & then theres a cap you can screw off of the valve body, then you can screw the shaft out.
On the end of that shaft, there should be a rubber washer that when you screw the shaft in, that rubber washer would close off a opening down in that valve body to shut the water flow off. Could be, that rubber washer has come apart & blocking the passage way & preventing water to flow into the heater.
Theres two types of valves that look like that, one will have the shaft with the rubber washer on the end, that you'll need to rotate several time to open or close completely, then theres another that will be maybe a 1/2 turn rotation to open or close & theres a ball inside of the valve body with a hole threw the middle.
Both types of valves will work the same, but will be less chance of the ball type to have a blockage, unless something was in the water lines from the pump to that ball valve.
You can unscrew the water line fitting where it connects to the brass elbow on the water heater tank & see right quick if you have any fresh water flow going into the tank.
You could as well while you have that fresh water line off, open one of the faucets on the hot side & blow into the heater tank & see if you get any flow from the heater doing that.
