my toilet has this really annoying problem in that when its just been flushed for hours afterwards condensation literally runs off the front of it..

ive tried tricks such as reducing the inlet pressure but nothing seems to work.

its a low level (not direct on the pan though) and a plastic cistern vented through about 3ft of pipe direct to the outside... hmm theres a thought....

The water going into the cistern is too cold, the air in the room is too warm and moist, so it condenses on the cistern, and drips off.... until the water is the cistern has warmed up a bit, or all the moisture in the air ends up on the floor under the cistern.
I think you need better ventilation to clear the moist air, and you could try to insulate the cold feed - does it run through a cold loft?
I don't know what you mean by the cistern being vented through to the outside - do you mean the overflow?
 
yes the toilet is downstairs at the back of the property. and the overflow pipe literally exits the top side of the toilet cistern and straight out the wall to outside. I did wonder if putting a tundish on it and putting it into the pipe from the cistern to the bowl might help the situation..
toilet is mains fed which runs through the house before reaching the toilet
 
Ours cistern does the very same, especially after we've used the bath or shower. We dry the condensation off the cistern, as part of drying the bath/shower, tiles.

ive just aquired an extractor of the type you fit INTO the cieling and vent out through the wall so hopefully this will help, I can only presume the old council Xpelair just snt as fit as it used to be. its certainly makes enough noise :LOL:

just got to try and find the best run for the hose as theres a chimney in both the corners of the room upstairs so I have to get round them as I presume one of them originally came through into what is now the bathroom

Mine too, never given it a second thought. I don't see how increasing the ventilation will work. The air temp in the room would need to be the same temp as the water to eliminate the problem.
 
also debated making a gutter along the bottom of the cistern and funneling water into the pan. thing is its creating pints of water and its all ending up in the by the toilet due to the gentle gradient the house has at that side (dont you just love old houses??)
 
If you can extract the moist air with the extractor, you should end up with warm, dry air instead of warm wet air. So the problem will be solved. If the source of the moist air is showering, bathing, damp towels etc, better ventilation should help.

Having said that, we have the same problem, and although we don't yet have extraction, I'd be suprised if it made much difference. I just checked the relative humidity - 70%. That's a lot of water in the air.

Does anyone NOT have a wet dripping cistern?
 
With a little bit of jiggery-pokery you could put it in the loft as the FE tank :LOL: :LOL: :LOL:
