A few years ago I was in a customer home doing a heater repair. I got in a conversation with the woman who said she was having a lot of trouble with her low water usuage toilets backing up. She had two bathrooms in her home and because of the toilets low water usuage per flush, the waste does not have enough water to keep the waste lines clear.

Two months ago I installed a new low water usuage toilet in my girlfriends home. This morning her toilet backup. She never had any kind of problems with her old toilets.

The first thing I noticed when I installed my girlfriends new toilet was how little water it used per flush. Another thing I noticed was that the device in the new toilet was not the standard float type found in all the older toilets. It had a large cylinder type device that would lift when flushed and allow the water to exit a large hole in the bottom of the tank creating some kind of vacuum to pull the waste out using very little water.

I have heard of this problem with the newer type of low water usage toilets before so this seems to be a problem with many of the newer toilets.

What can be done to prevent a backup toilet because of not enough water per flush?

Are some toilets able to allow more water per flush thereby allowing more water to flush the waste lines properly?

seems to me that your a having a problem with the anti-sipnhom diaphram located under the base of the ball cock, you mad need to adjust the flux capasitor. if that doesnt work, install a prv where the stop is on the wall, then make sure you turn the set screw on the prv all the way to left as far as it will go, just before it about to come out.
