Hi! Planning on getting a swimpure swg. We can have it installed for $180. My husband wants to install it but I thought we might be better having Leslie's do it in case there are problems? Are we likely to encounter any problem? He is pretty handy. Also once system is installed how long before we can swim. My son just went in our pool for 10 minutes yesterday and the chlorine had him sneezing and irritated. I don't want him swimming it in anymore until we convert. Thanks for your help.
