how many litres does a toilet cistern hold?

Answer 1

in england and wales

as some have said older ones 9 or 7.5 litres
whatever age yours is it will have been designed to go with a pan and remove the waste with that much water. you may be able to reduce the amount of water used by adding a filled bottle or a brick and see if it still works

for current cisterns there are two maximum volumes
for a single volume flush max 6 litres
for a dual volume flush 6 and 4 litres (not 3) i.e not exceeding 2/3 of the maximum flushing volume

whether there is single or dual depends on the maker and style

some modern units use much less that the maximum

NOTE :the current Water Regs came in in July 2001 not 2002

with those 50 litre cisterns it can be really difficult to sit on the loo, but sometimes they are useful for those times when a big flush is needed :)

Answer 2

Toilet Cistern Capacity

Answer 3

The usual Defra standard these days is 6 litres. Although slightly more than half the cisterns installed in the UK still exceed this (about 7.5 to 9 litres). Larger cisterns are becoming increasingly rare, typically 11 to 13.5 litres. You would be waiting till (next) Christmas for a 50 litre cistern to refill.

Answer 5

Most toilet cisterns currently installed in the UK provide a 7.5 litre or 9 litre single flush.Regulations in force since 2002 require the installation of a 6 litre single or 6/3 litre dual flush only.

Answer 6

Normally modern cisterns have an adjustable valve that can be set to 4, 6 or 9 litres. The 'Euroloo' is inefficient and often requires several flushes.

My 1968 double syphonic, close-coupled loo can get rid of a bucketful of pingpong balls at the first flush

Answer 7

At this time of year the mains cold water supply can be quite cold. This in turn cools the toilet cistern right down which is why moisture in the air, of which there can be a lot in bathrooms, condenses on it. Try improving ventilation in the bathroom, opening the window a little. I don't know if it's severe enough to be spending money on running an extractor fan or dehumidifier for hours at a time.

Answer 8

Fewer litres nowadays because the Water Authorities have had an input for manufatures to conserve water. The UK have followed the European standard as of late with smaller cisterns which are more appealing on the eye.

Answer 9

6 litres

Answer 10

it depends on how big your cistern is. If it is an old loo it will hold loads - if it is a newish modern loo it will hold a lot less.
