I would not recommend Hillcrest. Technician arrived on site and informed me it would 5-8 thousand dollars to replace my hot water heater (6 years old) before even looking at it. After finally listneing to what the problem was he made multiple phone calls to "Dave" and finally replaced the PRV valve at the water inlet, gave me a bill for 585 dollars and left. I now have 30 psi of water pressure, barely enough to run an upstairs shower and the original problem (drain line from expansion valve constantly running water) is still there? I have decided to call in a real plumber to troubleshoot the problem a hot water tank installer could not. BTW, the tank in question sells at Home Depot for $985 ???? Beware.
