We just had a plumber out last week. Since he left we've noticed hot
water in bathroom sink will sort of turn itself off unless we have a
good size stream coming out. Cold water is fine. Turn cold on low stream
and it stays on. Will this work itself out or do we need him back? He
replaced seats and valve stems. Prior to this I had changed the washers
but I guess the valve stems were shot. So he replaced them both. But now
if I turn on hot water to the point of a slower flow and not full stream
the flow is shut down to almost nothing by itself. We've dealt with this
place for many years and I'd hope they'd correct this IF it's a problem.
But is it? Is this normal for new seats and valve stems? Will it work
itself out or do we need them back?

See if the handle/stem actually turns by itself.
If not, the washer is swelling due to the hi temp.
The washer material may not be suitable or else the factory
overtightened the bibb screw; overtightening will deform the
rubber and the temp change allows it to "grow".
