Replacement Cap Assembly for Korky 528

The item shipped fast (overnight), and I repaired my fill valve. Great service as usual.

Big box stores don't carry this item. Some (but not all) hardware stores have them on the shelf, but it's best to stock up with SupplyHouse and have them on-hand. Saves time and money to replace a seal instead of a complete flush valve.

Best price, availability and fast shipping.

Excellent price with super fast delivery.

The product fixed the problem.

Keep these on hand! Have used Fluidmaster for decades. These Korky fill valve gaskets fail within 2 yrs like clockwork. The design that requires the plastic cap w/gasket instead of just the rubber like gasket is wasteful and negative for the environment. In over three decades, Ive never had to replace a fluidmaster fill valve in 2 yrs due to software wearing out. If you prefer repeated short lifespan, Korky is the brand for you and your customer.

Very reasonably priced from SupplyHouse and delivered quickly. Replacement cap was very easy to install (to replace Toto part in Toto fill valve). Fill valve now works perfectly and quietly.

Needed to fix torn one after 2 months. Refill of bowl would fill then stop then fill then stop 3 or 4 times til full bowl looked at diaphragm and found tear. Replaced now works great like it should.

Best under $10 value to fix a noisy toilet. Happy wife too! Great pricing when sourcing part.

I have Toto toilets in my house and one of them was not refilling properly. I thought I needed a new Korky refill valve. I did an Internet search with my problem and luckily landed on the SupplyHouse website. I quickly learned from their site that a Korky Replacement Cap could solve my problem and it was priced at less than $2.00. I ordered the cap and it arrived within 48 hours. I placed it on the toilet and it immediately solved my problem. Thank you SupplyHouse for great problem solving, tremendous pricing and wonderful customer service.
