Don't know if anyone has any suggestions, but my new toilet has a dreadful flush. It's a close coupled type and I had it fitted by my mate who's a plumber, so I know it's been done properly. It takes two flushes just to get rid of any amount of paper. I know that we are supposed to be trying to conserve water with these modern toilets, but if you have to flush them two or three times it defeats the object. I don't know if it's possible to change the innards so the water would drain faster. I will ask my mate, but I thought in the meantime, someone on here may have some experience of this.
Cheers.
