a disappointing 12 l/min in my kitchen after installing a new combi in a new

isolating
tap that fed that spur by a few more turns. It had been opened only by a
couple
of turns during my initial tests.

Thanks Andy, I was going to check this over the weekend anyway,
(particularly after Christians comments yesterday) but a good tip
nonetheless.

Cheers!
