I just wondered if anyone has converted a flow-controlled setup to a simple on-off switch.  is it simple?
Having had a few failed pcbs and no need for flow adjustment, it seems like a way to avoid future hassle

Yes, it's dead easy.  Re-wire the pressure switch (if it's not already wired up); it's very simple to do and add a £2 in-line switch from Wilkies.  Even a Geordie can do it.

Or build one of these:

My original is still going strong for over a year now; no issues with it what-so-ever.

Many thanks Tosh - I will have a go at this at the weekend
