Hello. I'll be purchasing a Toto Drake and in my research learned that the fill valve is not the best that it could be. Should I put in a Korky 528MP or a Fluidmaster 400A when the toilet is initially installed? Thanks in advance.
That replacement fill valve sounds like it is going to be thing to do. https://www.korky.com/sites/default/files/media/product/pdf/528MP_3.pdf is the instructions.
I was thinking that, but I was unable to envision how that slide sticking would cause the on-off behavior. Still, maybe you could take the existing valve off, and clean it with dishwashing soap and get things sliding better.The whole thing?
I just remembered that the video mentioned that the float had to be good and loose. When I had this apart, the float was a bit snug after it went back together. Not super tight, but not real loose either. Could that account for this fill-stop-fill-stop thing?
The Korky 528MP, with the silver ("Platinum") cover, is the replacement that I would recommend.
If you have a 1.2 gallon per flush toilet, the flush valve must provide a higher proportion of refill water to the bowl than it did with a 3.5 gpf toilet. So that "higher" is with respect to old fill valves.On the 528T, it says: Higher refill ratio for optimum performance in TOTO toilets.
