OK problem is, my dad in-law has a mobile home and neither of the toilets will flush out. He recently bought it and had it moved hence this is when the problem started. The toilets have not flushed out since day 1. Everything else seems to run out OK, shower sinks etc... Could this be a venting...

I am remodeling my bathroom and I have a question. Behind the toilet, sink and bath tub is a brick wall. I want to leave the wall exposed, but the problem is all my drain venting is against the wall. There is a crawl space under the bathroom with very easy access. Is there some way for me to hide...

Do they make a ventless toilet? My friend has installed a new toilet and learned after that the previous owners didn't install a vent on the drain.

What is the plumbing code in feet from the toilet waste to the main stack without venting. This is in a concrete basement floor.

My question is the total amount of feet is allowed from the mainstack to the center of the toilet waste without venting
