Will a pressure assist toilet solve my problem of an improperly angled waste pipe. My plumber did not angle the pipe correctly because he did not want to block a basement window. If a waste pipe with not enough pitch causes my solid waste not to flush would a pressure assist toilet fix the issue?

Probably not is my guess - but how FAR is this pipe(length)... Your "handle" is carpenter?? What do you think??

A picture would help or can you better explain what pitch the drain has?

No, pressure tanks are for low house water pressure, not clogged or improperly fitted drains.

Pressure assist toilets aren't for homes with low water pressure, Brian (ma0641). In fact, these toilets have a required pressure range requirement or they may not work at all!

Pressure assist toilets are simply another choice for the consumer... some people LOVE them and some people HATE them, in my experience.

As noted above, these toilets will NOT increase chances of waste going down the drain any faster... just increases velocity of waste THROUGH the toilet is all.

Like Bob (ballengerb1), I would like to know what pitch (if any) is on this drain pipe?
