The shipment box was beat to hell and looked like it had been returned as it had the box seams taped multiple places with clear cheap packing tape. The 1-1/4 MNPT threaded connection was protected be a thin cardboard ring, but it got impacted in shipment as indicated in attached picture. Informed Amazon supplier of damage but R/R of old WM-6 and replacement with WM-23 79.6 gallon tank was trouble-free. I used Kevlar-laced sealant rated for PVC and threaded a female crossover to 1 in PVC slip connection, o-ring union, ball valve, on to my water supply. I topped the air pressure charge back up to 38 psi before install, was about 25 psi as tank made in 2022. Make sure you check/recharge air charge at top Schrader valve at least yearly to get maximum amount of service water before your pump cycles.

They sent me a "last year" model or something, different fittings and base than what they advertised.And I ran it anyways after buying all new fittings.Well, the main pipe has fallen off the bottom 2x so far.Bad factory design, probably why they don't use that style anymore.I'm on almost a year leak free now since getting my own fittings to replace the factory fittings that you aren't supposed to remove.....
