my downstairs toilet doesnt have an overflow pipe going outside should i fit one our leave it?

Answer 1

Why do you need an overflow pipe for in a toilet?

Answer 2

As Xenon says most newer variations of cistern filling devices overflow to the toilet therefore do not require an external overflow pipe. First indication of a problem will be a slight flow into the toilet even when it hasnt been flushed you may also hear cistern filling continouslyThen again if it is an old fitting you have and an overflow has never been fitted you may have got lucky for years would recommend an upgrade rather than fitting external overflow. New filling devices are about 15 - 20 pound complete

Answer 3

What I've seen as the usual fix for this is, you run the overflow out the side of the cistern (the top part) and down and in through a small pipe to the top of the toilet bowl... if it overflows it run's away down the toilet drain, not flooding your downstairs toilet.

It's a good thing to have one, a flood may cost BIG bucks to fix, carpets and furniture, electical items, underfloor dampness etc etc....

Answer 4

As two others have said modern toilets do not have external overlows. They overflow back into the bowl. As some one else has suggested, overfill the cistern and watch to see if water flows back into the bowl. If it does you are fine. If it doesn't, look at the cistern and see if there is a plugged hole on the rear, or more normally the side. If it has one of these holes then it should have an external overflow. Have fun.

Answer 5

In UK toilets are being fitted with internal overflow pipes. If an overflow occurs the water runs inside the bowl. Only on old toilets did they require external overflows.
AS an experiment try filling your cistern with a bucket of water to try to overflow it, see where the water runs.?

Answer 6

Answer 7
