My tenants recently told me that they have constant clogging problems with their bathroom sink and had me come take a look at it. I found the following 3-trap configuration:
This was done because the sink is too far to the right for it to mate with the drain in the wall via a standard p-trap configuration. This seems like the wrong solution to me (it was done by a (non-plumber) contractor when I was living out of state). A guy in the plumbing section at Home Depot didn't like it either and suspected that it would lead to clogs.
I replaced two of the traps with one of those flexible pipes and was able to make the connection with the remaining trap being rotated slightly - not ideal, but I'd suppose that two (roughly) 45˚ bends are better than what was there previously. There seemed to be no alternative way to connect the sink to the drain given the 1-1/4" pipes and fittings available at HD.
My Questions:
Is it fair to say what was there before was incorrect and was contributing to the frequent clogging problem?
What is the "right" way to solve this plumbing problem?
