Toilet Filling Slowly

[DB1789]

Hi all,

A few weeks ago we noticed the toilet started filling slowly along with an odd ‘snoring’ noise... (Only way I can think of describing the noise.)

Anyway, about a year ago it was filling slowly and replaced a split diaphragm washer after a quick google and problem solved, so first thing I checked was this washer again.

Looked fine, so just popped it back in.

The odd noise stopped when filling, but it’s still been slow for a few weeks. I’ve replaced the washer just in case it was that, and it’s nice an tight, but still slow to fill.

Any suggestions?

If there's a filer or a flow reducer on the valve it could be gorging blocked.Bob

Could be dirt or scale in the seating is it on high (mains) or low (tank) pressure and is the correct seating fitted?

Check that the mechanism is moving freely through its travel when the float drops and rises. Take everything apart and give everything a good flush and clean under a tap (make sure small parts can’t go down the plug hole). Check all internal apertures are clear and use a toothpick and old toothbrush to clean. Check diaphragm again for grime and any splits. Take care to reassemble correctly.
