toilet cistern

[spannerman]

i have had a new toilet fitted with a macerator but the cistern leaks
into the toilet pan and then the macerator starts up is this due to
bad coupling to toilet pan

 

[herbert]

usually means the syphon seal has a problem or the cistern is overflowing into the bowl

 

[Plumbstar Tom]

as per above

pull the cistern lid off and have a butchers

 

[spannerman]

is that seal were syphon fits to pan or inside cisten
it is not overflowing if you turn water off it empties cistern

 

[herbert]

gotta be the seat on the syphon to the cistern then mate .. dont force it but the syphon will probably just twist off quarter turn if it is a 2 button type there may be a bit of debri holding the washer off its seat
