I would not purchase anything from this company. I did purchase a component for my pool heater to convert it from gas to propane. My plumber was busy, like most contractors today, so I had to wait for him. When he told me to make sure the city would approve a propane heater I called and the Fire Dept. told me, I could not use propane, so the part I bought but never installed was of no use. I called to ask if I could send it back and pay for postage and a restocking charge and just get store credit, not a refund and In the Swim told me NO WAY, under any circumstance, since it was past 30 days, so I don't recommend this company.
