Most of them use a standard tap washer.

And according to type, Type A has an o ring around the gland so they
don't dribble when open. Type B has no o ring and does dribble when
draining down.
There is only a small difference in price so best to use the O ring type

Or fit washing machine taps as I did.

I use service valves, and pipe the output through the wall into the
nearest drain or a suitable soak-away location. Saves messing about with
hoses being draped through the house.


Sounds neat, but can you find a drain at the ch's lowest point?

And the thought of draining even a clean ch system into a soakaway
sounds a bit gross.

I used a 40L trugg emptied a couple of times - not too much bother if
you have underfloor access.
