Hi All. I purchased from Home Depot and had installed a new, Delta shower diverter. I can't find the model number (still looking) but it's that basic model they sell. Might be called the Linden (somewhere in the neighborhood of $90-$150 in cost). Anyway, after installation it was not used for a while but now it's in use. I used it a few times just to fill some cleaning buckets full of water and it was fine. The tenant moved in, took a shower and fine. After the second shower it would not shut off though. Not a drip....completely running full force. I took it apart and toyed around with it a bit and it was working ok then voila...at the next shower it again would not shut off. Any advice? Thank you.
