Stubborn Toilet Requires 2 Flushes
I have a ground floor two-bath 20 year old condo unit over a crawl space. The toilets are about 10' apart. The hall toilet works well, but the master bedroom toilet always requires a 2nd flush to get solid matter to go down. The first flush is lethargic, with everything moving slowly around in a lazy circle which produces little effect. A minute later, the 2nd flush is considerably more vigorous and everything goes down.
I have talked to two different plumbers who were in on different occasions to fix other items. They looked the toilet over, but they had little to offer. I think one did try probing the entry holes with a wire or something (didn't seem to have an actual tool available for this). They didn't seem to think a new toilet would necessarily solve the problem. I believe obstruction in the pipe to the street was raised as a possible suspect, but not with much conviction. I don't see how that could be the cause if the hall toilet works OK, as does the problem toilet on that 2nd flush. All opinions welcomed. Thanks.
