Changing wc gasket, between cistern and pan

[saveasteading]

There was a leak at the rubber doughnut thing, so I've fitted a new one, and new bolt connectors. But it's as bad.

I have either over or under tightened,  I'm thinking.

So tomorrow I will try again. Daylight will help.

Should I add plumbers gunk as a matter of course? The instructions say nothing.

 

First though I intend to fill the cistern, but not flush,  to check it's not at the fixings.

Conclusion:

 

You did a shit job lol.   

The ‘leak’ is seldom from the doughnut washer, and more often from the bolts. 
 

When did this leak? Continuously, or when flushing? 

If it’s a daylight issue, then please do consider fitting a light in the bathroom. Your family will thank you.

Perhaps it's the nightclub vibe.

Full report later. I'm pretty sure it's only when flushing.

Spellchecker changed that to blushing.

 

It was late so I just emptied the cistern, mopped the floor, opened a can and hoped for a plumber's secret to be revealed.

Eg

whatever you do don't under/over tighten.

 

There are no instructions and the bottom nuts are plastic,  so I assumed that it should be finger tight only.

 

The new gasket is a foam rubber thing so could be squashed a lot more, for better or worse.

Thanks I took all your expert advice to do it again properly.

Everything tighter and a dab of fernox to make sure.

 

In my defence...

Knowing more about steel buildings than plumbing... if there is a leak in a steel clad roof the likeliest problem is a screw with a complete bodge covered in mastic. Second is a screw overtightened, breaking the seal from the washer.
