Leak on toilet inlet with new fill valve

[smulsey]

I've fitted a new fill valve on my toilet as the old one stopped working properly.

In fitting the new one I've found the copper pipe that feeds the inlet isn't quiet straight and so pulls the valve on a slight angle.

As the new valve isn't sitting flat in the bottom of the tank so the rubber washer isn't making a seal and it's leaking around the inlet.

It's not possible to get tools around the new nut as there isn't enough clearance, and no matter how tight I'm able to get the nut (and bearing in mind the instructions say don't over tighten) it's still leaking.

What would you recommend I could do to stop the leak?

Rather than mess about cant you take the inlet back and swap for one that isnt defective?

Ive found they always leak if only hand tight so i always nip them up with a spanner or grips. The plastic back nuts can strip their threads easily though if you over tighten.

I replace them fairly regularly in work along with syphons and have never had to use any sealant.

Oh I mean it's the actual pipework of the house that's not straight rather than the valve I just bought being defective.

I've just taken some photos, maybe these will help. So the pink line is the inlet pipe, it's hard to tell on the photo but it's not straight and so when tightened onto the valve it pulls it on an angle and leaks around the nut where the blue arrows are, I guess the rubber washer inside the tank isn't flat/tight.

Have you only tightened it finger tight then with you saying you cant get tools in there? They always leak if not tightened enough.

Could you get to it with one of these?

Personally i would remove the cistern, tighten the inlet and then replace. Or, cut the copper pipe and replace with a flexi with a built in isolator to make things easier in future.

I tried with the new nut which I could only get finger tight, then on your advice tried the old nut which is shaped slightly different so I could get a spanner at it but even so it's still pretty hard to get at so I didn't manage to get it much tighter. Still leaky.

Ha yeah I thought that might be where this is heading. I think I might just call a plumber tomorrow. It's getting a little beyond me now, it was just supposed to be a simple swap!

Fit a 6" flexi

He's only done the top nut (cistern nut) hand tight
