Gerber ultra flush defect?
Posted by Maribeth on October 17, 2001 at 22:36:59:
Purchased and had professionally installed two gerber ultra flush toilets. These toilets are in two adjoining bathrooms which share a common wall in an upstairs condo building.
When toilet"a" is flushed - the water from toilet "b" in the adjoining bathroom drains (is sucked from the toilet). Toilet "a" will fill back up normally - but toilet "b" has to be reflushed in order to have the water fill up.
This also happens if toilet "b" is flushed - toilet "a" has to be reflushed.
Pls advise -- is this an installation issue, defective toilet -- or are the toilets too powerful for this condo -- condo was built in the 1970's.
Any help is greatly appreciated.
