I have high standards for service done on my home and Errol completely exceeded all expectations. He was polite, professional, very clean, and extremely knowledgeable in his trade. After purchasing a new home, I had an Iron/Sulphur Filter installed, UV sterilization system, as well as an Reverse Osmosis Filter. During the process of installation, Errol was able to identify mistakes in the set up of the prior owners water softener, such as improper size tubing, material of tubing, and drainage location. For example: 50psi tubing was used for something that requires 100psi tubing, and the short drainage tube, for some reason, went back into my well -- the makings of a potential basement flood. He had all the materials on hand to correct the prior issue in a timely manner. He was also able to recommend how to sanitize my hot water tank to remove the sulphur producing bacteria that may be there as a result of the prior system, and reprogram my previously incorrectly programmed water softener. I absolutely recommend Errol's services as finding someone this knowledgeable in their trade can be a rarity. Thanks again for the great service!
