Heater split nuts

I don’t know how else to phrase this but they are what I expected and they are the correct size parts

Right parts and fast delivery

Circuit board flow meter shut down the pump but left the heater on ! Fried multiple parts and was able to repair thanks to available parts from Spadepot.

I will buy this product again when this one breaks.

I need it to prevent the spa from leaking all over the floor. It is s replacement for a broke part.

Great Staff

I purchased the heater union split nut 1.5 inches. The inside collar was a little small so it would not go around the pipe. I called and the rep said maybe file it down a little. I never thought of that and it worked out fine. The guy sounded genuinely interested in solving my problem and said to call back if I had issues. Very pleasant to talk to. I book marked the SpaDepot web site to use in the future!
