Hello, I am a commercial pool operator in Houston Texas. I am seeing that this is more of a residential pool forum, but thought I'd join. I've worked around pools for close to 15 years and have my Aquatic Facility Operator certification and know a good deal about caring for pools. (Operating a big 270,000 gallon pool isn't all that different, I just add chemicals in in the 100's of lbs) Just started a new job not too long ago that only deals with maintenance/repairs of pools and am always looking for new sources of information. Does anyone know of any good reference books/guides for commercial pool repairs?
