Replacing Screeching Toilet Fill Valve?

[Radam87]

Hi

My toilet makes a loud noise when flushed. When I pull up on the fill valve cable it stops during the flush.

Is it a simple job involving isolating the feed, draining, clipping the old Fluidmaster out and clipping a new one in?

This is the part.

Is this the correct replacement?

Many thanks

If replacing the complete valve then isolate and drain water first, unscrew and remove old valve and replace with new valve shown in the second link.
However I believe you can unclip the top and replace the washer/diaphram on it`s own.

I unclipped the top and pushed the new one on then clipped it to lock in place - it appears to have worked. Bottom was in okay condition.

Do the levels look about right? Are there critical levels that need to adhered to?

Level looks spot on. That marking on the cistern shows the fill level for a 6 litre flush. So long as the float is free to move up and down without catching on the cistern wall it should be fine.

Thanks - I tried to recreate the height of the previous unit and it looks similar if not ever so slightly lower.
