  • Shower – No Water Flowing

    Posted by Jimmy on April 21, 2023 at 9:27 am

    Stepped into the shower when water was hot and all of a sudden the water stopped coming out after maybe a minute of total running.

    Water is still flowing at 3 sink faucets and toilet is flushing. Hooked up to 50 amp with 120 water pump and then turned on the 12 water pump. As expected, still no shower water. I unhooked the shower nozzle from the wall and no water coming out of the wall.

    We did have the water level down to zero one time on the TechLink screen though water was still coming out of the faucets. Wondering if shower needs to be primed and if so, how would I do that?

    Strange that faucets work but not the shower. Any help would be appreciated. Thank you.

    There is a cold water supply and a hot water supply to all faucets and the shower valve. If the others are flowing hot and cold water, the problem could be the shower valve.

    Another clue you shared is no cold or hot flow from the shower hose connection at the wall of the shower. So, my best guess is the shower valve.

    Hope this helps, all the best.

    Thanks Rudy. So would this be a shower valve in the shower stall or down in the bay?

    In the shower stall. The shower valve is the only place both cold and hot come together. Down in the bay it would be rare for both hot and cold water sources to the shower fail at the same time.

    So, cut the hot and cold to the shower off. Remove the shower handle and shower valve, replace valve and see if I guessed correctly.

    If you get the valve at a plumbing supply, folks there may be able to help you with this diagnosis too.

    Our current coach had no hot water flow in the shower. Cold worked but not hot (no flow). A new shower valve fixed that problem

    My Marathon guru Bernie always starts with the simple questions. He immediately asked if I knew how my shower handles work. “Of course I know, I’ve been using this shower for 5 months. The top knob is water On / Off and the bottom knob is for temperature and both turn right and left.”

    Come to find out after exploring many possibilities and one plumber service call that the lower temperature control knob (right and left) is also a double valve that not only turns right and left but pushes in and out as a water on/off shut off. How stupid of me.

    My behind side must of pushed this knob in when I bent over to wash my feet and never realized I shut the water off This is what my family calls a “Jimmy”.
