Thanks dadams much appreciated info
My system is a home designed and made pump utillising a stop solenoid so water doesn't pass through the pump whilst parked and a 0.7mm atomising jet. The pump was measured at 150psi continuous

markk, still a dickhead from years ago then, explain what I don't know what I am talking about? I got a perfect response from dadams, no one else told me anything near that essential info, just bollox

safechav, stick to your XR3i's
