Water leaking on the way into toilet bowl

turbodiesel

Hello All,

I've water leaking on the way into the toilet bowl. It the pipe going from the cistern into the bowl when you flush. It's from the seal at the back of the toilet bowl where the water feed pipe enters the bowl.

How can i repair this. I'm assuming i need a new seal. I just wanted to know what to ask for and is it a simple push to fit seal(seems to be flexible enough).

Just so you know what I'm talking about please have a look at this video link. It's about fixing the waste pipe leak but you'll see the seal i'm referring to above the pipe he is working on. It looks exactly the same type of opaque rubber that mine is with also a right angle feed. It about 10 years old.

Thanks

Davy

Do you have the same type suite? As in the cistern doesn't sit on the pan?

You can just remove the rubber, and put it back to its original shape. Sometimes, pressure is applied, bends it out of shape as causes the tear drop.

Its called a grommet as far as I know. Think it is a standard size but measure flush inlet pipe once bowl removed. also bring old grommet with you to store.

Shut off water. Flush toilet.

remove screws affixing toilet pan to floor.

Gently remove pan from sewer pipe and flush inlet pipe. Make sure you hold the flush inlet pipe when removing the bowl so as to avoid damage to the pipe where is connects to the cistern.

If this pipe is in poor condition, you can replace it too.

Put a bag over the sewer pipe with a rubber band to stop the smell coming up sewer pipe.

remove old grommet. Clean up and dry insert area where grommet was.

Clean and dry end of flush inlet pipe if using old one. If you are using a new one, you may need a new washer that is used at the cistern end. Think it is a tapered one.

Insert new grommet. Use a little silicon between grommet and bowl to ensure water tightness when dry.

You may also want to use silicon between pipe and grommet.

Gently replace bowl, inserting flush inelt and sewer pipe.

Screw bowl to floor.

Alternatively, you could remove the cistern instead of the pan- this would avoid any possible problems with the sewer pipe. You would have to disconnect the water pipe in this case and unscrew the flush inlet pipe under the cistern. whichever you feel more comfortable with...

Thanks Davy, If a new seal was gonna be sav a tenner i would go with that. Wont cost anything to give it a go with some vaseline (recomended on one site) or some silicon. Thanks.....

I don't think I'll have to remove either the bowl or the cistern.

It's the exact same layout as on the video. The top of the 90 degree water pipe coming from the cistern has a screw fitting so i imagine that would be easily enough to remove and then it should slide out of the push fitting at the back of the bowl.

I'll have a look at the seal and either replace or use some silicon.

Thanks.

well, I was going to suggest that in my post, but I decided to give the full method.

I didn't list it because that part of the pipe that goes into the syphon outlet in the cistern (there is a long enough insert depth) has to be pulled down to get it out/in thus putting some pressure on the grommet, which you are trying to seal (i.e if you had the pipe out, new grommet in, silicone and now you are trying to jiggle the pipe back into the syphon you could upset the seal).

So you might have ended up with the same problem despite new grommet etc.

But hey if it works, fine. It will save a bit of work. You can always go the long way if it doesn't

Well, I drained the cistern, loosened the pipe off and pulled the seal out. there wasn't quite enough room to remove the pipe but plenty of room on the pipe to move the seal back and line both the pipe exterior where it makes contact with the seal and also line the seal exterior where it makes contact with the cistern. Tightened it all back up and everything seems well.

Thanks for the help.
