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.
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?
