Pipe connecting problems for double sink vanity in bathroom

JamesAA · Oct 13, 2017

Hello. It looks like the J-bend P-trap was put on backwards by the previous homeowner. The taller part of the P-trap should be connected to the "T" connector. Surprisingly it doesn't leak.. When I tried to put it on the correct way, the "T" connector ended up being way too high for the left and right connecting arms. The water would be traveling upwards. I think the previous homeowner put the P-trap on backwards in order for the T connector to be lower. But this could not have been how it was originally designed to work. How can I get around this problem? I can't figure out how it was designed to work. Sorry, I don't know much about plumbing..... please forgive my terminology if it was bad.

Thanks

You have to cut and shorten the two tailpieces down from the sink bump everything up make sure the P-trap is facing the right direction and is at the right height so everything drains properlyView attachment Screenshot_20171014-043140.jpg

remove the pop up strainer you have installed on both sinks
replace with a grid strainer, \
this will raise the drain up, above the wall inlet

your next option is to cut the wall open and lower the pipe exiting the wall

Thanks for the help guys. Why did the architect of the house design it this way? Shouldn't he have made the wall inlet lower? What is the advantage in a higher wall inlet?

It's not the engineers it's the guys roughing in the plumbing. It depends on the year of the house. In the old days they were roughed in a little higher for various reasons.

House was built in 1958. I have a couple more questions. Will really short hair stubble (from shaving) clog drains? And I've always heard conflicting views on Draino/Luquid Plumber. What's the verdict with these products, useful or damaging? If Draino is bad, is the baking soda and vinegar method effective and safe?
