We just had a Reverse Osmosis water filter installed to replace an existing unit.
I had purchased one from Costco and Pete said he could install that one or install a unit that he supplied and include a 2 year warranty. His price was the same as the Costco unit so we went that way. Sorry to ramble on but we had another plumber here before Pete and his price was 120% more than Pete's price??? We had great service and it took no time at all...I will always call Pete the plumber first! Lesson learned here...shop around!
