I'm installing an automatic air vent in the 22mm feed pipe to a
shower pump. The vent uses a 1/2" to 15mm connection. I was told the
neatest way would be to use a 22-15mm reducer in the 22mm equal tee,
off which is the vent.

I've never used these before so some advise would be appreciated. I
can see that it replaces the 22 mm olive, but I'm not sure which way
up it should be. The obvious way has the reducer flush with the back
edge of the 22mm nut when assembled, the other has it sticking proud
about 5-8mm.

My other question is how is the seal made with the 15mm pipe which
inserts into the reducer. Does the reducer act as an olive and
compress onto the pipe. This seems unlikely because it looks quite
solid brass not capable of being crushed upto the 15mm pipe.

thanks


Don't really know - never used a reducer. What's wrong with a 22x22x15 tee?
Much neater!
