I bought 6 Jandy valves from Discount Pool Supplies Online | Pool Equipment & Parts 5 are fine & one looks like it is used or rebuilt. The surface is rough, looks like it is chipped from having the top popped off & the UPC symbol is smeared. I asked for an RMA and they told me to get lost. I'm simply concerned that I don't want to replumb my setup with a part that I don't trust.
