Flushing problems with low flush American Standard.
Have had an American Standard 1.6 gallon toilet for a few years now and have always had periodic problems flushing solids. As my health has improved in the last few months, thankfully, I have also being having to double flush and plunge regularly. I do not know the style and it does not appear anywhere on the unit.
I can tell you that;
The throat opening is 2.75 (not 3.75) as posted before edit
The drain is 4" and goes to a 2000 gallon cistern
The drop is 1/4" per foot
It's vented 10 feet from the fixture, the maximum distance allowed by code.
When flushing at anytime the action in the bowl is very passive. I have seen other low flush units I can only describe as having 3 times the action when the tank is emptying.
Only 50psi from the pump to assist rinsing the bowl, shouldn't really affect the action greatly I believe, could be wrong.
Having some time on my hands now this problem is on my " to do list " and want to see what can be done if anything before I go out and spend money on a new unit. I suspect the vent should be closer to the fixture. The last thing I want to tackle as the drain is not accessible from below. Would have to break through foundation block to access the drain line in the non crawl crawlspace.
Your comments and suggestions are greatly appreciated.
