LEAKING NEW FLUIDMASTER 400 BOTTOM ENTRY FROM PLASTIC CISTERN NUT.

[PHIL269]

Hi
If anyone can give me any advise on how to stop a leak please ?

I have just installed a new Fluidmaster 400 float valve bottom entry brass shank.

It is now leaking with a drip from the bottom white plastic washer which fits onto the cistern.
I made sure the rubber washer was put on cone end facing down inside the cistern but maybe I tightened it too much, worried about untightening now in case leak become worse.

Not sure what to do now, do I remove it and start again, says hand tighten nut in instructions , I used a wrench and maybe tightened too much, would this of damaged rubber washer ? do I need to buy another valve ? Would sealant help ?

Thanks for any help please

You would need to remove it to have a look.

Thanks for the info, the leak is dripping down the brass shank from the plastic washer.

Faulty washer, cracked cistern or not tight enough.
