Do I have a siphonic toilet?


Recommended Posts

Old toilet in our old house is very slow to drain. It will fill up the pan, let out a gurgle or two then slowly drain. Some-one suggested it may be a siphonic toilet, something I'd never heard of till then.

The middle seal let's the water out, the one on the left doesn't move unless I manually lift it. Since playing with it the water drains quicker but not what I'd say with any force to remove solids.

 

I've tried chemicals, a short auger, garden hose incase there was a blockage.

Definitely not a siphonic WC.
 

Take the cistern off, replace the flush siphon, and that’ll get you through until the rooms re-done. 

Cheers.

It lets out water fine from the cistern, just doesn't want to drain from the bowl with any speed.

I may need to relent and phone a plumber, or buy some enzymes.

 

The toilet had several packets of old medicated toilet paper in the room, my suspects are that's caused a blockage somewhere.

It's also a vertical drop to the space below the floor (barely a crawl space) and enters the ground.

Take the toilet out and get a set of drain rods down the pipe.

 

Tried it from outside but wasn't sure what access point was for the toilet.

 

But, as per usual, your right. It's been siliconed around the joints (can see it in the photo), so presumably peel that off and would need to be redone on fitting.

Sounds like a partial blockage in the drain. 

 

Symphonic wc do fill up the pan but then drain out more rapidly than you describe. As I recall the waste outlet pipe is a smaller diameter on a syphonic  so I don't think you have one of those.

Taking that out is a suicide mission. The cement going into the clay will all expand and likely shatter the clay pipe. 
Get a proper janitors mop, jam it into the throat of the WC and hold it down. Then flush.
When the pan fills full of water use the mop, lifting it up and then thrusting it back down rapidly, into the throat of the loo, again and again to punch the water through the U bend of the pan. 

That’ll have as good an effect as anything, and after that, if no discernible results are achieved, you may as well admit defeat for now. 
Remember that if you buy a modern loo to replace this, it will have the crappy 4-6L flush capacity so don’t get your hopes up there. 
Best route to maximise efforts first as last would be to buy and fit the new intended loo, and whilst removed use that opportunity to clean the pipes out with rods / other. 
Bon voyage!!

The pans are much fatter at the base also iirc.

Thank you, we do have a mop so may try that although not an old school janitor style- there may be one in the house somewhere.

 

As a secrete extra tidbit we do have the original blue prints but wary of unrolling them. The plan is to get a reprographic place to do it, copy and digitise and return to the tube. These may have the drainage plans drawn.

House was built in 1936.

Going to need a specialist.

The toilet is under the window. The drain nearest to camera feels bone dry and filled with gravel with drainage rods.

The circular one has the sink like an open drain directly into it, and maybe the toilet as it was a lot foamier than expected from just a hand wash - tried bleach with the mop action. This is also blocked as when using drainage rods with a rubber circle attachment I can hear it about waste height on the down pipe, there's definitely leaves down there.

 

Around the house other rectangular ones I can see the water level, one looks filled with small polystyrene balls and one even has a tree route growing into it and is packed with soil.

 

Buy an old house they said...

Time for the good old waterjet boys to have at it. Don’t bother with a plumber, as that’ll need sucking out not just pushing further downstream. 

 There's a localish waterjet company, no idea if they offer suction too, but going to phone them tomorrow.

Kitchen sink has slowed down already, no idea if it's same issue or we've been over zealous with washing dirty pots and bits of food down there already.

Check if your insurance covers the drain companies attendance. ;)

I did find a can of the stuff in the house (we accepted it with contents, got about 20 different part china tea sets!). And tried that as the suction cup could be changed to "toilet mode" did hee-haw.

 

Drainage poeple hopefully coming out tomorrow afternoon, £93.20 an hour and they'll go over any major findings and costs (ie they wont just dig a hole to rebuild a pipe and charge you)

It’ll be money well spent, and the guys usually go at it at a decent rate of knots. ?

Hopefully, then after that it's a roofer out to repair some tiles and flashing around a chimney breast.

 

Finger's crossed nothing else major is needed before central heating goes in. The cooker lasted 6days from currys before failing.
