My son has just bought a flat and I'm in the process of redecorating before
he moves in. I've noticed that when you flush the loo the water rises quite
high in the bowl and goes down a lot slower than it should. I've not used it
in earnest yet and I image that any solids wouldn't get flushed away as they
should. I'm guessing there's some sort of blockage in the u bend of the wc.
I've not tried anything yet but was thinking of having a poke with an old
bit of hose or something. I'm open to suggestions though. Is there anything
made for the job or perhaps some chemical treatment I can use?
PS - the reason being that toilets are made, very sensibly, so that the
channel gets bigger as you go further round the U bend specifically to
prevent blockages. Anything that makes it past the top of the bend will
disappear and anything that doesn't will fall back into the pan. Blockages
in the actual U are very rare.
You say it's a flat. You don't say whether it's a ground floor flat or not
or what sort of drains exist. First step is to find the manhole covers and
see if the chambers are full or empty. If the drains are blocked then the
blockage will lie between the lowest full chamber and the highest empty one.
If all the drains are clear then it's in a downpipe. Every blockage I've
encountered has been in the drains, usually a tree root or a collapse or
some other snag which catches something solid and allows a build up above
that. The local council or water company will be your cheapest option. NEVER
ever use dynorod type outfits who will rip you off in spades.
If the drains are shared by more than one property (technically then called
sewers) and the property was built before 1/10/1937 then they will be the
responsibility of the local water company who will repair anything FOC as
long as you are aware of that and actually call them.
Actually they are bloody common in an old toilet in a hard water area.
Thats exactly where the scale seems to form.
The the tirds lodeg agains it..
I know, I causticed and chipped out two here years ago..should have used
I can confirm that. A bog was flushing poorly and the water level rising
after 19 years in . So I donned nosepeg and shoved hand down and around
the bend. 'Why do they called him Harpic? Cos he's clean round the
bend'. Boom! boom! Mr Derek.
I felt what I thought was a faulty moulding. I took the pan out and
found a build-up of scale that filled nearly half the area of the pipe.
Chipped it away and now fine. I get the same problem with waste pipes
that have a shallow fall. Hard water area of course.
Had a meeting with the head of a water companys legal team two weeks ago to
discuss this very issue, its on the way but a couple of years away at the
moment - her best guess was 2010. Watch out all those people who`ve built
conservatories over the top of private sewers.
How come people don't know how to deal with a partially blocked loo these
It depends where the blockage is but generally speaking it's normally in
the trap of the loo, in which case a well aimed and dumped (rather than
poured) bucket of water normally does the trick. After that the string
head mop is a good one or anything large enough to get a reasonable piston
effect going with the water.
If they fail it's time to start following the soil pipe as best you can
opening (carefully) and inspection covers or manholes as you go. If the
soil pipe is blocked it probably be down to sanitary wear or a nappy,
neither of which should be down there in the first place.
Dave. pam is missing e-mail
And when some idiot in the family has flushed a blocked loo, in spite of
being told not to, so that it is now full up to the brim and not draining at
all, a wet and dry vacuum cleaner is the least unpleasant way to empty it.
Similarly for stuff backing up in a gully or an inspection chamber.
It may well be a siphonic toilet, these can give the appearance of being
Try flushing some kinds of solids and paper and see if it taken away before
Hot kettle and caustic soda
I'll et the big girls blouses tell you how dangerous it is, suffice to
say wear safety glasses if you want to peer at a load o boiling caustic
After that tip some brick acid down and leave over night.
The caustic removes the turds, the acid the scale.
By the time its all a mile downstream its all neutralised itself too.
Thanks for the suggestions.
Just for the record the property isn't all that old. I'm guessing 20 years.
There are another 2 flats below this one and I'm assuming they all share the
same soil pipe. As there isn't a complete blockage the soil pipe would
normally be empty and so I would have thought a loo on the 2nd floor should
flush normally unless there is a blockage in the loo itself.. Anyways, I'll
give the various methods a go and see how I get on.
