Condensation on toilet.

Apparently popping a tropical fishtank heater in the cistern to get the water to around room temp will sort it out :p.

A lot of small bathrooms don't have any sockets. I wouldn't want a black cable draping about either...

put up with it tbh, not unless you have a habit of hugging your toilet or something.

think of the children!
 
stick a bucket of hot water in the back of the cistern everytime you flush and with the extra cold water added from the cistern fill thing to cool it down it should be about the right temprature to not cause condensation
 
It isn't rising damp. It is atmospheric moisture condensing.

I see it from time to time, and the condensation covers the cistern up to the waterline of the tank and no more. It tends to be when it is quite literally frozen outside and roasting warm in. Unvented, like mine, makes it worse. Wall tiles & everything else in the room, apart from the cold pipes, are bone dry.

how could it not be rising damp? its defo an option..

if the cistern is fastened directly to a wall, this will cause it to cool right down too if the wall is very cold/damp/not insulated..

if you pack the cistern off the wall this can help a lot..

obviously having a shower and not having a vent, opening the windows or doors will cause a lot of damp in the room.
 
Because he isn't complaining of damp walls, but cistern. For rising damp to be so localised as to be creeping up the back of the toilet alone, and then wrapping itself around the cistern is a bit too much of a stretch for me. I'm not discounting it, but there's already an obvious reason as to why it is happening so why go for the convoluted alternative?
 
yup its because the temprature is uber low outside, the cold water coming into your houses is uber cold, it fills up a cistern and makes the cistern like the temprature of a fridge.

the warm air in the room causes moisture to form.


anyone thinking its rising damp has been smoking crack
 
im confused now at people thinking it could never be the case, yeah he may not have rising damp but it is defo an option..

like i say, the water coming into my home is very cold but my toilet has never had the moisture issue..

from what ive seen working on toilets over 15 year is that their are issues like, rising damp, causing the room to fill up with moisture when the heating is on..

obvious things like leaks and long showers with no ventilation or super cooled toilets fastened to very cold exterior walls when all toilet cisterns should be spaced off the wall..

if you'd like i could show you a toilet dripping with water from the amount of moisture in the room, all caused because of rising damp..

and i could show you millions filling up with icey cold water and becoming covered in beads of water.
considering the weather right now I think its pretty safe to say its because the water is cold.
anyway if he wants to test it he can chuck a bucket of hot water in the cistern to warm it up.

get all the moisture off the outside of the cistern and look on in amazement as it stays dry


The next time im at the pub drinking an iced cold beer and the glass starts to become moist on the outside I will inform the bartender his pub has rising damp though
 
why though is the cold water that cold to the point in attracting condensation? unlike a pint of ice cold beer a toilet shouldnt be that cold if he has his heating on and the cold main to the property and any internal pipework is fitted correctly..

but lets say the cold main is ok, fitted 2.5 foot underground and comes up through an insulated pipe, that would mean the cistern shouldnt be filling with ice cold water..

but yet still gets cold, why then would it still get cold ? maybe rising damp, causing the wall the toilet is fitted to, to become super cooled..

their also needs to be moisture in the air, how else could it build up on the toilet? it obviously has to be there for it to happen..

some toilets dont have a whole lot on them, most people wont care but ones ive looked at have been dripping, as if they had a leak.. their was excessive amounts of moisture in the air, because their was a leak/rising damp.



you talk about it as if its normal, nothings wrong. it happenes to everyone, well no, it is an issue, their is a problem which needs looking into.. whether its worth fixing is upto them.

Yes, the water is that cold as to be attracting and condensing moisture from atmosphere.

An insulated pipe is not going to reduce the temperature of the cold water by much at all, the pressure of unvented mains water flow will ensure that the freezing cold water stays resolutely freezing.

There does need to be moisture in the air, and that's quite normal. Living habits such as plant life and lack of ventilation generally can increase ambient humidity.

A leak isn't going to uniformly cover the cistern alone, most leaks will occur at the bottom of the tank. Damp would need to be found elsewhere other than condensation on the cistern for it to be rising damp.

Stop using the term "super cooled", you have no idea what it means and it has no relevance at all to what you're saying.
 
no it wont reduce the temp, it will increase it, frost does not penetrate any further than 2.5 foot under ground..

and if the main, obviously unvented, when would it ever not be.. comes up an insulated 4" pipe into the middle of a kitchen, it then should NOT be near freezing..

i have no idea what you're talking about, maybe water reacts differently in scotland ?

That's what I was getting at apart from talking in negative, it doesn't really matter about ground frost penetration as the water is already coming from a very cold source although it would clearly help keep things cold. It would be kept cold by supply pipework, ground temperature and pressure, and the last few meters of pipework being insulated is barely going to raise water temperature anything significant.

Obviously the mains supply itself is "unvented" those terms relate directly to mains supply pressure - depending if the property still has an immersion heater tank & gravity feed cold water tank then the bathroom is likely to be fed from that; this would be a vented supply. This supply of water, due to the relationship between surfaces and bodies of water with air it will be marginaly warmer.

Water in Scotland is like water anywhere else, except probably a bit colder than anywhere else in the UK.

yeah im talking about the cold main, not a tank fed cold water system.

the point in insulating it as it comes up into the building it obviously not to warm the cold up but to maintain its temp as it comes up, to stop it freezing. normally a builder that fits mains into buildings and they never do it properly..

the source of water probably wouldnt matter though most of the time because the main water temp would stabilize as it ran underground before getting to each house, the earth maintains almost a constant temp above freezing, you then want to try and keep the main water supply at that temp all the way into the property.. im unsure of the temp, i think i read between 5 and 15 between uk summers and winters
 
Unvented supply is going to be colder than vented.

The point in insulating cold pipes is to help prevent freezing, nothing more. Most house builders don't bother.

The source temperature matters as this will be broadly transferred through supply, current water temps will be around 5-6deg c. They will cool, to the point of freezing in domestic pipes, with the onset of severe cold spells.

When cold spells hit, people stick the heating on, and relative humidity tends to rise with ambient air temperature. The two temperatures diverge and the cold glossy surface of the enamel attracts condensation from the warm air and allows it to form.

Not ninja damp. :p
