Thanks in advance! I'm installing an acrylic tub. Ordinary 30x60 soaker, no jets or anything. Instructions call for a bed of mortar beneath the tub. A few years ago I installed an acrylic shower pan, used thinset, and within a few weeks it started to flex. Somebody on the forum suggested I used the wrong stuff. So I want to be 100% sure this time. I'm going to post a link for a product, hoping for a thumbs up or down.

Hello knowledgeable folks of doityourself.com! I have a kitchen sink that knocks/thumps when turned on. The sound usually stops after a few moments of running the water. This happens for both hot and cold water. It does NOT happen if the handle is turned very slowly to the on position. The faucet has recently been replaced, the knocking occurred before and after replacement. This only occurs in my kitchen sink, which is the highest faucet in the house. Worth noting, the home was winterized in January and water was turned back on at the end of February. Before I spend days trying a variety of the options I have found online, I thought I might reach out to those that know more than I do! :) Thank you!!
