You have now basically seen all the working parts of the valve the only moving parts are that float and the pink diaphragm, which is why it is so easy to service.Īh, I forgot to add. Pull that out, either by hand or with a needle-nose. On the bottom of the black tube is a white plastic filter. Then, under the cap there is a long tube attached to a round top. If blisters or it looks worn or you can't push on it around the little black pin, you can replace it with the Korky R528 cap, available at Lowe's and many local hardware stores for less than $3. Are there blisters? Is there gunk in it? If gunk, give it a good rinse off. Then, holding the valve body with one hand so you don't inadvertently unlock it, twist the little cap off counterclockwise 1/8 turn, remove it, turn it over and look at the pink diaphragm in it. Then, pull the (white or blue or green or silver) cover off the valve, pinch the little arms attaching the float to the valve cap like you're pinching tweezers, and lift it straight up and off. What you are going to do is turn off the water, pull the refill hose off the valve with one hand while you steady it with the other (and don't twist the valve you can twist the hose to remove it). Then, if that doesn't solve it, time to service the valve. They're actually a very simple valve design with a minimum of working parts, and usually can be fixed with just some easy service you can do at home.įor your specific problem, that noise, first check and make sure that your water supply knob is turned all the way open.
I have five of these in our house, and so are familiar with them.
