In my pool, I have two white PVC pipes that push water out, where jets are supposed to fit to increase flow rate.
The diameter of these pipes is 1.5 inches.
I purchased a 5-pack of "Pool and Spa Eyeball Jet 1.5" Threaded to 3/4" Open" jets from an online retailer.
I was sent a pack of 5 jets where the diameter of the threaded portion measured 1.75 inches, too big to fit in the 1.5" wall pipes.
I returned the pack, and requested the correct size.
Again, I was sent the same 1.75 inch pack back. The product is a Pooline item number 11211C. I found an independent description which measures the threaded portion as 1-1/2" MIPT.
Below is a photo from the website referenced above showing the MIPT, and photos of the items I received with a tape showing measurement.
Before I return these items for a third time, I want to make sure I am purchasing for the correct width. Am I simply being sent the wrong item, or am I asking for the wrong item? If so, what should I be asking for?
