The plumber came at the appointed time, explained the charges up front (it was $125 for the call out and for an hour of work to investigate the problem and give an estimate). He then identified the problem in 5 mins. and said it would need a valve replacement. He said he would have to order a part which would take about a week to arrive and cost $80. On our approval, he ordered the part, phoned us when it arrived (in about 1week), gave us an appointment for a day that was mutually convenient. On the day, he phoned in the morning to give us a two hour window when he would arrive. He arrived at the appointed time and fixed the part - it took a little longer than normal because our water softener was in a cramped corner of the garage, and he had to dismantle a fair amount of it before he could fix it because of the lack of space. However, it was all done within the remaining 55 minutes credit we had from his first visit. He only charged us for the part cost ($80) in the second visit. It was a pleasant experience. The plumber was professional, competent and fair. The problem is fixed, and I got good value. Update: I used Water Quality Plumbing again on May 14, 2014, this time to fix a leaking bathtub faucet at a rental a few blocks away from my home. I had called a different plumber first, one I had used before for work in the rental, but his bid seemed outrageous. He wanted $270 for labor and $150 for parts. He claimed the entire stem and diverter had to be replaced. Since I had a very good experience with Water Quality Plumbing, a few weeks earlier, at my home, I decided to give the job to WQP instead. I phoned early morning before work and received an appointment the same day, and I was given a couple of windows. Rather than act as an intermediary between WQP and the tenant, I asked WQP to contact the tenant and schedule an appointment at a convenient time, and told them to go ahead and do the work if it was around $200. They set up the appointment with the tenant for that afternoon during her lunch hour. They phoned me from the rental after inspection and confirmed the diagnosis of the first plumber, but said they could do the work within the 60 minutes covered by their call-out charge of $125 with an additional $90 for parts. They had phoned because the total was $215, above the $200 threshold I had given them. I gladly approved. They completed the work satisfactorily and phoned me again to get the credit card information for payment. All in all, a most satisfactory experience.
