ok, so all installed.Will do...
Started the pump and was very dissappointed. Didn't seem as tho the accumulator was actually there!
Bit of mucking about but eventually figured out that the pressure was to high at 30psi.
The Shurflo pump has a cutin pressure of 25psi (+/-5psi) so I dropped the accumulator pressure to 20.
Still not as good as I thought it would be but I can fill a 1 litre jug before the pump kicks in.
That would be around 3 hand washes during the night at a guess without the pump starting up and annoying the other half.
I also increased the pump pressure a bit to help.
Was it worth it? yeah I think so. Time will tell when I take the MH out next.
