    Hi Guys

    I am looking for a replacement LPS for an Optima 701 and can NOT find one.

    If you look at the diagram/PDF for the boiler it is NOTHING like the drawing (Ref-114), it is actually a big black unit that protrudes forwards (i understand this is just for a better diagram layout).

    Does the part still exist as it is switching at 3.6 bar thus the PRV is constantly passing like a tap as i need mains pressure in order to get boiler working, everything else works fine....

    Cheers

    It looks nothing like that unless it has a plastic cover/shroud over it?

    It has 4 connections coming from it 2 are used as in diagram and wired to the PCB (N/O Contacts) and the other two are just spades, prob N/C..Not sure what they are for...

    I will see if i can get a pic tomorrow mate..

    I have stuck a gate valve on the fill loop as temp fix and got it 'balanced' as best i can so the PRV is just a dripping now.....

    Thanks for replying.

    Will do, it looks like there's just a rubber shroud covering the PSwitch.

    I think you are correct and it will be a standard 3 pin...

    I'll post a pic tomorrow.

    Thanks
