Non-flushing toilet

yes, but that is why typically you stick an air valve in..

Where would I find it if I have one and what is it likely to look like?

It's likely to look like one of these:

It's normally at the top of the stack - often in the roofspace to avoid taking a pipe out through the roof. Sometimes there's just a short stack behind the toilet, with an AAV just above cistern level. You may be able to create one of those - depending on how the output side of your bog is plumbed.

I notice that some the SF AAV's are designed to fit 40mm pipes rather than the usual 110mm. One of those would be easier to retro-fit, as long as you can tee a 40mm vertical pipe into the toilet outlet.

As I said I don't appear to have a soil pipe, stack or whatever it is called. So that is why I was wondering if this was a factor in the poor flushing action to empty the bowl.

Firstly, is this a ground floor or upstairs loo? If it was upstairs and the was no way for air to enter the soil pipe you'd get a very strong suction effect sucking most of the water out of the pan. The effect would be less marked but similar downstairs.

I'm pretty sure that it is a requirement that soil pipes are ventilated one way or another though. You say your loo has an S trap that descends through the floor. Where does it go after that? Usually a soil stack or vent will be concealed in a boxed in enclosure in the corner of the loo or in the room on the other side of the wall behind the loo.

A common cause of a poor flush is a partially choke sewer. If the blockage is only partial the water level might not rise much if at all, just not fall as quickly as it should. Have you checked any inspection chambers?

Posting pictures of your bathroom might help.

It's a ground floor (bungalow). The toilet is against the wall, the pipe to the sewer being directly below the S and in the ground. The sewer inspection lid is 2m away from the wall. Other similar houses have a soil pipe. I used to have a soil pipe at my old property.

The sewer was (supposed to have been) checked by the water company prior to my moving in and the report (as found in the searches) said all was clear. I now suspect that the previous owner had issues with flushing and was trying to sort things out prior to sale.

Some funny and non-standard things have been done over the years (see my threads re purlins). I just have a feeling now that someone thought the soil stack was unsightly and removed it.

The sewer inspection lid has sunk at one side a couple of inches - it has been like that a long time - but I guess I'll have to have a look.

Further upstream the end of the garage has been converted to a utility room with a loo and shower. I can't believe the pipes have been laid under the existing garage so I would suppose there is a route via my next door neighbour. Would that sort of thing been allowed say 15yrs ago.

The ball valve for this toilet has just started leaking and overflowing as well so have just replaced that with a Delchem side valve and low pressure adapter. Seems to take an age to reach a stop

- fairly quickly filling then reducing to drips for a long time as the valve eventually closes. I'm trying it on a low level to start with and will raise it if the flush flow into the bowl seems slow - but it seems healthy at the moment. It is just the emptying of the bowl that is poor.

Yes, and as *I* said, you may be able to *create* a short small-diameter stack alongside or behind your toilet.

What does your toilet outlet connector look like (photo?) and where does the ongoing connection go? Could you replace it with one of these?

Never heard of a *low* pressure adapter on a fill valve. Are you sure it's not a high pressure one? These usually add some flow restriction to the inlet.

Do let us know what lurks in the inspection chamber. ;-)

I don't think so - there are two photos on

One showing the toilet with its integral bend. The wall it is against is shown in the other photo - window nearest the garage with the sink and bath outlets and the cistern overflow pipe. The sewage inspection is next to the brown bin. There is no sign of any stack pipe and it appears that there has been a bit of subsidence on the sewer route. I believe it was checked. There is no build up of water in the bowl though I gave it a good pumping the other day with the cut-off end of a large fizzy drink bottle.

"The valve is also accompanied by a low pressure restrictor seat (red)"

The cold water to the bathroom is supplied from a header tank in the attic.

Weird. I'd try it with no restrictor if it's only coming from a bungalow's loft tank.

Really? 112 lines quoted for a 2 line reply?

So bite me. I usually snip, in fact probably do it more often than most here but I was on my phone at the time and selecting text for snipping is a bit of a pain.

What's your contribution to this thread apart from a whine?

Ah, that takes me back a bit! My (long dead) in-laws had used to have a toilet like that in their bungalow - with a low level cistern and J pipe, and with the outlet connected into a clay pipe in the floor. They had a vertical soil pipe outside, vented at eaves level.

I can't think of an easy way of adding a vent to your setup. If you want to do an experiment to see whether it would make any difference, you could try flushing the toilet with the lid of the inspection chamber propped open.

Don't know why "weird" - the ball valves I've looked at specifiy HP or LP and I'm not having an issue with the cistern filling up except the old brass one was sticking on on occasionally and the new one appears to have fixed that.

Reply to
AnthonyL

As appears to be the case with similar nearby properties.

Good thinking.

Nothing weird about a low pressure ball valve. What is weird is having to put a special "low pressure adapter" to cope with low pressure. Just an odd use of words really. Normally ball valves by default will cope with low pressure and any adapters are used to cope with high pressure.

That said, I'm sure that there are purpose designed ones specifically for high pressure mains.
