I have a six plus year old Livia 90 Semi Automatic. It builds up pressure and then releases through the release valve, sometimes every 10 minutes, sometimes not for a couple of hours. Always quite a surprise! Where is this PStat valve that can be adjusted and how can I get an electronic version of the manual? I have emailed Pasquini. If someone is qualified individual, I will certainly pay for some help if it is warranted.

This is a simple fix. This has been fixed on newer units with a rewire kit. This rewire kit is for Pasquini Livia 90’s with serial numbers PRIOR to #49000. We have them listed on our website Part# 90000 for $30.00.
You can contact me for this part - If you are local we could install it for you. If you do not fix this problem soon, you will need a new pressure release valve. It would also be advised you get a microswitch #7633905 for $13 at same time as the rewire kit. If you still require a manual we could provide you with a digital version.

My experience is working over 10 years at Pasquini as a master technician running the home repair sales and service center.
