Pipe blocked at certain junction.

tcooley

Hi all,

See the pic attached. The area marked in red tends to block up once a month or so. Its easy unblock by screwing out the cylinder and pushing on the buildup of tissue, poo etc. Problem is of course its right outside back door and its a bad stink. Plus of course I'm not too happy getting splashback myself.

Is there any way from looking at pic that I could put in a pole or whatever to unblock without unscrewing that cap? Could I use the cap at the end instead and push on from there?

Thanks all,

Tomas.

What is actually causing the blockage?

My guess is there isn’t enough fall, or something is interrupting the smooth movement of waste in the pipe (more likely the latter.

You need to get this fixed, once and for all.

What is the "cylinder" for?

I would suggest dropping the horizontal run, and joining all outlets into it like that, rather than having the T out of the toilet into the horizontal. like the blue pipe in this (bad)drawing.

Also I would suggest that you talk to all the users of the toilet about what and how much TP is appropriate to put in the toilet.

I'd try turn the inspection port so it's on top of the pipe. Tissue is probably getting caught in the knuckle.

Looking again perhaps that's where the toilet waste is so a non runner. 🙈

As previously suggested, turning that inspection port/ rodding eye upwards would help.

What tissue or poo is going into that stack?

I can only see 5 waste connections there, none are 4 inch from a toilet.

Is there a hidden WC connection, or is that red circled bit part of a WC connection?

If that red circled bit is a WC connection ,a plumber needs to change that piece for a 90 bend with no inspection port. Put rodding eye on end of stack instead to clear a blockage.

The fitting outlined in red is the wrong fitting for where it is, should be a standard black tee piece with the branch going into the wall.

Had an issue like that in a run here and it was caused by a 2 inch pipe being too long in its join such that it was blocking half the 4 inch pipe
