I've had a look at the valve block and spoke to the previous owner.
The link pipe went straight into the block on the left.
I was hoping this block had some kind of funky one way valve/unloaded set up, but it hasn't.
Its just a distribution block.
Has a cap in the front, the gauge, a 160psi safety valve and the valve at the back is a fusable plug, designed to release pressure if there is combustion heat in the receiver.
Oddly, the inlet is very restricted by the fusable valve.
Why the air inlet isn't in the capped off 3/8 hole I've no idea!
Seems this ran with no one way valve and no unloaded valve.
I guess without an unloaded you don't really need the one way valve?
It must have worked ok but is it acceptable to have it set up like this?
I could add a one way valve but unless I can find an unloaded that isn't mechanically triggered by the pressure cut of switch then I'd need to replace the switch too. Don't really want to do that as the honeywell switch it came with is very adjustable.
Without a one way switch it's very much relying on the pump valves not to drain down.
I guess I could run a one way and no unloaded but won't that strain the pump and motor?
Maybe I should talk to my local compressor shop.
