Hi all, I am replacing my existing water softener due to a crack. I had an old system that was a dual tank setup, from pentair. It was one tank stacked on top of the other tank, threaded together. The threaded area started to leak after 5+ years of service. After tightening, the threads sheared off!! Due to space constraints, I need a similar setup to have carbon and the resin in one tank. The vortech with mid-vortech seems to fit the bill, however I have read some issues with the cap separating from the plate at the bottom. Aside from that, how would one change the media and the resin??? I spoke with a rep from Enpress and they said that there is a way to do it, via some type of small vacuum tube, but he didn't give details... So, what is the collective thought on this type of tank? Avoid or buy and why. Option #2 - get a domed tank with normal distribution tube, put gravel at bottom, toss in the resin, get carbon and make some pouches out of ultrafine screen material. Any recommendations on what kind of screen I could use? Some type of NSF plastic of course. Thanks in advance.
