Can a Aqua Trol RJ be hard plumbed 1 1/2 PVC to the return jet. I think I see it comes with hose type unions for the return, but other configurations? 1 1/2" or 2" PVC?
Perhaps all I need is to buy some standard 2" unions and reduce it down to 1 1/2". Will a standard 2" union thread onto the cell? Much cheaper to buy the RJ than the HP model.
