Hi Peggy,
I had a similar problem with a bathtub drain. We moved into a house
where the guest bathroom tub drain was slow. As years went by, it got
slower and slower.

That's pretty much the situation here.

I too tried everything, not including sulfuric acid, and
was totally stumped. In despairation, I called in a $100 per hour plumber
with a power snake. He sweated and strained and finally ground his way
through a long lost shampoo bottle cap that had become lodged in a pipe
before the trap.

I don't THINK anything has fallen into it...at least not in the 4 years
I've owned the house. But I can't rule out that something could have
when the PO lived here.

The cap had accumulated hair and what not making the seal
almost perfect. It cost but it felt pretty good to get rid of the problem.
The plumber said the worst thing he ever ran into was a marble that had got
stuck. It came out only when the pipe was removed.

By the way, thanks for all your helpful info. on marine heads.

Glad to do it. I just wish this problem were as easy to solve as most of
the ones on boats! But I think you may be onto something. I'm gonna buy
a sink plunger and see what I can accomplish with it. If that doesn't
work, I guess I'll have to call in a plumber.
