Can you make a dual flush toilet flush more water?

Anonymous user 03/03/2024 - 2.53 PM

Last year we had a dual flush toilet fitted in our 1900 terraced house. Since then it has blocked several times. We are able to use it only if nothing apart from liquid is put down there - luckily we have a downstairs toilet! A plumber friend thinks the reason it is blocking is because the sewer pipes are at a right angle rather than a gradual slope and the new toilet doesn't flush enough water to force the waste past the bend. Is this likely to be the case? What can we do to fix this issue apart from having expensive sewer pipe work done? It would be really great to be able to use the toilet in the bathroom again and other people must have had a similar problem being as there are so many terraces out there! Any advice would be brill. Thanks

Have the old syphon removed from the cistern and fit a simple flush valve this is a flap that lifts when flushed, these give a good flush because they let all the water drop with no restriction. This will not cure a problem with the drain and you should get it ckecked out.

Hi Natalie, While it's true that more water means less chance of blockages, it's highly unlikely that this is the case for you. If the pan blocks every, or almost every time solids are flushed down, then it's almost certainly a blockage (usually in the pan connector) within the outlet pipework. The time taken to block indicates how far from the pan the blockage is. If you can flush once and the pan backs up, then the pan connector has caught something - usually a 'rim flush' - whereas if you get three or four flushes fine, then the pan backs up, this would indicate the blockage is further downstream. I've got big hands, but can still usually feel the inside of the pan connector by feeling round the 'U-bend'. If you can't feel anything, try removing the pan and checking both the pan and down the pan connector. I hope this helps! Why not try posting the job and get a contractor out to have a look for you? Thanks, Dave
