Slow Fill Cistern

Gerard93

Hi,
I have an upstairs Toilet that fed from a tank in the attic, its very slow to fill any way I can improve this??

Thanks!

Mr E

It happened to me about 6 months ago (cistern would take 15 minutes to fill).

In my case, I needed to replace the diaphragm (the part costs less than a fiver in a hardware shop). You can do it yourself, but your water needs to be tuned off first.

I have the same problem with 2 cisterns.

They both have the same plastic water filling mech that you have that is piped from the bottom of cistern. However, the water flow on mine is even slower than yours in that pic! It's a trickle. Used to be fine, but not anymore.

Thanks for that. I had considered whatever is the "valve" though didn't think it'd perish in 4 years.

Anyway, changing the diaphragm should be much handier than changing that whole inlet assembly.

Does the ballcock (float) move freely and does the button that the ballcock pushes to cut off the water inlet move in and out freely.

Yeah, there is VERY little movement on the button.

Is it out as far as it can go. Try vasoline as a lube if its sticking. Is this affecting only 1 toilet?

It is 100% the ballvalve washer , search other threads for a guide on how to replace it , it would be a good idea to also check the orifice for blockages too, or even replace it for a red, black , or green one if the one fitted is a white one , as they allow more water through when refilling.

Thanks for the replies

No problem with this plenty movement with this and the cut off is ok

Thanks Sullzz will check this

The diaphragm loses its shape over time due to the fact that 99% of the time it is in a closed position. The rubber part eventually remains in this "closed position", causing your issue of water trickle. Less than 1€ in any plumbing suppliers. 2 min job. See the video above.

Thanks dodzy will sort it during the week!

Have the exact same problem with 1 toilet for months. Was going to post a thread on it but the ball valve washer replacement looks like it'll fix it. Must get myself to a plumbing supplies place.
