Lately, we’re having a problem with the shower in our spare bathroom, which we renovated about a year and a half ago. The shower will only stay on for a short while before the water then goes back through the faucet. If you pull the diverter, it will stay on for just a short period, and then go back down after a minute or so. When we did the renovation, we left the old shower head on, which we liked very much, and got a new shower valve and trim set. When I called the manufacturer, they say it’s a problem with the shower head and the flow restrictor, so they can’t help. I know nothing about plumbing, but was looking for some input before I go and have the shower head replaced. Does this sound right, or could it be an issue with the shower valve/diverter, or something else?
Thanks a lot for any recommendations-
