Title: Cheaper Elsewhere -Not good if you have higher water pressure
Review: This fill valve is a lot cheaper at Lowes. I have also found out that it does not have a very high pressure tolerance. If your water pressure is over 60 pounds this valve will run constantly through the overflow tube, wasting a lot more water than you are saving.I'm going to replace it with an 'original' toto valve and see if that is the issue or if all the new ones are the same.An update. I tried a second 528T and it had the same issue. Leaked water into the overflow tube when the pressure reached around 70 pounds. I talked to Lavelle (Korky) support and they stated that the valve is rated for 60-80 pounds and could take awhile to seat. After two weeks of leaking water I changed to the 'new' Toto TSU16A, which initially had a lot of complaints. It does not leak. Now we will see how long it lasts but at least I'm not wasting water.It's also cheaper than the Korky valve if you buy it through a plumbing supply store.
