Hello! I have a Toto Carusoe with a 1.6gpf and the old fill valve of TSU30A. I have had issues with this valve in the past with a loud squeal, not shutting off, and now a noise in the wall. I believe from looking at other posts that it may be water hammer. I do not know my pressure in the system. Cleaning the fill valve rubber seal does no help, and if I flip it over the water does not shut off. Partially closing the shutoff valve does not allow the fill valve to shut off the water. I have another identical toilet that has a small noise at the end of the fill up, but not as loud. I am currently draining the whole house to attempt to remove any water hammer issues. I am currently looking at 2 of the Korky replacement valves, the 528GCM for 24.98 with a 5 year warranty and the Korky 2x long life 528XCM for 14.98 with a 10 year warranty. Do you have any insight into which is the better fill valve? I would think the cheaper one with a 10 year warranty would be the way to go but I just don’t know. Also, the installers used a rigid supply line to connect the water supply. Should I replace this with a flexible hose as well if I replace the fill valve? Thank you!!
