Hello all, I am new to the forum and just starting out so please excuse my ignorance. I am glad I found this site as it is full of great information. I am helping my dad plan for his upcoming DIY inground build. He is in the very early stages of planning but is getting close to ordering his kit. I have a question about SWGs. My dad had considered going the SWG route for all the benefits so many people seem to enjoy (easier maintenance, less chlorine, more comfortable...). He was discouraged from a SWG early on due to information he got about having to replace corroded SWG parts at high $$$ as well as other pool corrosion issues. He is now considering a chlorine option combined with a UV filter to reduce the amount of chlorine needed. He's hoping this will reduce replacement parts cost and be more comfortable than the standard chlorine amounts required with non UV supplemted systems. We live in MN, I think his pool will be 18x36 a lagoon shape vinyl lined, possibly sport 4x5x4. We know that SWGs can have a higher set-up cost but this seemed worth it for the benefits until my dad found out SWGs would also require more money in parts more often.
1. Are there really greater parts replacement costs with SWGs and is their lifespan that much shorter than chlorine systems
2. Anyone have expierence supplementing chlorine with a UV filter? Will this reduce the chlorine by half as some have told my dad? Will the reduction be enough to effect comfort levels (dry skin, hair, and fabric fade)?
