I have a fluidmaster toilet and I have to fill the tank for it to flush, how do I fix it so it flushes normal?

Question

It just stopped working one day, it didn't refill like it should, and I managed to turn on the water and be able to flush it. But now I can't even do that. Even with the shower, and sink on, even with cold water. I looked inside and the little tube that deposits water is just dribbling now. How do I fix this?

Answer 1

sounds like it may be stopped up with lime  this should be $15 item at a DIY store just replace it

Answer 2

On some models you can take apart the mechanism and clean it out. You cal look at it and see if it is serviceable.

If not-Just replace it with a fill kit. They are not expensive.  A cheap one is about $10 and good one is about $15.

There is one that has no float or ball. Just a pressure switch---thats the easy way----check out Walmart, Lowes, Home Depot.

Answer 3

Doubt that you have a Fluidmaster toilet, probably just their fill-valve. Parts DO go bad. You can get a new one for under $10 at most Home Centers or hardware stores. Keep the installation instructions since they also tell you how to do maintenance if it fails later. Fluidmaster 400A is what you want.

Answer 4

I agree that a new ballcock is probably in order.  However you should make sure that your supply valve is not clogged.  Opening it and closing it a few times should improve the flow.  If it doesn't then replace the ballcock.  There is a  ton of information at fluidmaster.com.

Answer 5

you need to turn off the water, and replace your fluidmaster valve
