Considering a previous bad billing experience and everything I'd read on here, I was expecting the worst when I contacted Reliance about a problem with my water heater rental unit.
But, the two guys that fixed the problem were quick and did repairs that made sense.
I was given an afternoon service window (1-5pm) and they arrived well within that.
The problem was with the thermocouple and a (slightly) leaking drain outlet.
They installed a brass drain cap on the outlet. For the thermocouple, they didn't carry the part. It sounds like a common part you'd carry lots of, so, from what I've read here, I expected that'd mean a second service call at some unknown future date.
But, rather than wasting a trip to the parts supplier, they went to Canadian Tire, got the part, installed it, and now it's up and running again.
So, no complaints about this service call.
