the thermos has upper and lower inlet ..... it is connected without a valve at the top, I ask not to disassemble what is connected, this valve can be placed in the lower cold water inlet, it would be protecting the thermos or it has to go if or if where the water enters .... I hope it has been clear ... thank you very much,
I consult you ..... my calf has cold water connected to the upper entrance without the valve ...... I can connect the valve to the lower cold entrance .... I would be acting the same!
If the water inlet to the thermos is opened, you have a water tank, you do not need the valve because the expansion is released, it goes back to the tank, the valve will never act, even if you want to place it, you can install it in the lower inlet.
Good day Luis, to complete my knowledge, if I remove the plug of the lower cold inlet and put the valve it would not be fulfilling its function correctly ...
