I had a malfunctioning water softener. Dave came out, analyzed the problem, found a cracked tank, recommended a new unit and gave me a written quote for that and some other repairs. I researched it and agreed with his recommendation.
Very soon, I had a nifty new softener and 5 new faucets outdoors. Dave also found the leak in the softener's dump line (it was underground) and repaired it quickly.
I highly recommend Merit.
