Anyone know where I can buy resin to replace the resin in my DI counter top unit. The filters are about $25 and only last about 35-40 gal. That gets expensive. Thanks.
If you're only getting 35-40 gals out a DI filter then you should really consider an RO/DI unit. I live in S. Florida and our tap water is pure fertilizer (phosphate from sugarcane farming). I was using 2 Tap Water Purifiers inline with a carbon block filter and it was costing me a fortune. I priced out bulk resin and it still wasn't worth it. I would up buying a 100GPD RO/DI unit (new) on Ebay of a little over a $100. It works like a charm.
