I had called Zippy for the leak I was experiencing in my shower. It started out as a drip and after a short while evolved into a steady stream. I put the problem off because I thought I would have to replace the shower valve or something major. The technician showed the gauge measuring my water pressure at 150 psi and that this was the reason for the shower leaking and why my toilets were acting funny. He replaced a piece of hardware for me and fixed the shower fairly quickly and left a very pleased customer behind. Would definitely recommend Zippy!!
