So I have been on 3 pool jobs recently for various repairs and upgrades. Now, I can do PVC with the best of them, but I will say there is a bit of a learning curve with the piping and design aspect. I must say it is enjoyable. I like the challenge of figuring out how things were done and how to improve upon them as well as sizing new pumps and filtration systems. So yesterday I finished one of them, all new piping for a new 400kbtu heater. I did a heater bypass valve setup with a check valve and a bunch of other things like getting the solar working again. Client asked me yesterday to figure out a system and price to automate all the functions that exist manually right now. However I just rewired the entire setup, of which about 50% needs to be removed for the automated system, but I am still designing it right now. Point is, I haven't been this excited to do research since I started in Tankless heaters. Maybe I am just bored cause my family is out of town for vacation (daddy has to work) but this has got me interested to a point where I am thinking about getting into this more. I figure with a backround in plumbing (emphasized with tankless, which is all a pool heater really is) as well as my electrical experience I think there could be some good money in this. All the automation is really cool. Did you know they make pool pumps that are 100% variable...pretty cool stuff! They also make chlorine systems that run off regular table salt...no more red eyes or dry skin, you can swim under water with eyes open with no irritation...sorry, I know, I'm rambling. Who else is into pool work...what do you think about it?
