How hard is it to replace the tank? It looks like the tank just has a hex nut molded on top to screw off. Can I replace this myself and do I just need Teflon tape when I add the new tank or something more? (I will shut off the water and release the pressure before I try to take it off)
What should I replace it with? This tank does not seem to have a fitting to add air. From reading some of the other postings it seems some tanks do. Should I get one that I can add air to?
Thanks for any suggestions on how best to tack this.
