Pressure switch

On my 2017 warwick  XL the water pressure  switch keeps  clicking about every 10 min for about 4 seconds  rang smc they said back pressure  switch off have back it off as far I can still clicking anyone had this problem?

Is it still clicking around every 10 minutes, even when backed off?

Have you tried turning the other way, just in case you've gone the wrong direction?

I'd also check no taps are dripping or look for leaks around any pipes.  If the water is weeping somewhere the pressure will slowly drop and trigger the repeated pumping.
