Slip side union for 1" Neptune Flow Sensor

BPiers · Jul 20, 2017

So I have a slow leak on the slip side of my new FS-100.
We all know that the threaded side are BSP, so I can't just run down to the Home Depot and get a new union to thread on.

--Or can I? Would the slip side of the union mate up? What are my other options?
I'm a huge Neptune fan, but am pretty disappointed that a US based company selling a US based product makes it near impossible to get replacement parts!

No I thought I was going to be smart and do the same as I had a union where I was going to put my 1in and it wasn't compatible didn't make me happy but mine is working great
So cut it out and add the BSP one completely

I decided to unthread the union and pack the pipe with more PVC glue from the inside. Seems to be Okay-- but for others, and myself in the future when I need to change my plumbing around - do they sell these unions from Neptune??

$36.59 for two new FS-100 unions shipped from Neptune's replacement part site. For a little more than $20 more, I can get a whole new FS-100 that includes the unions and get it shipped for free from a retailer. Anybody know where to get these unions elsewhere?

Does anyone know if these work work? https://flexpvc.com/cart/agora.cgi?...MI8MK7_fq-2wIVgrfACh3lLg2CEAQYBCABEgKvPPD_BwE

While they aren't unions, slip would be fine for me.

Old Thread, New Knowledge: Cepex Replacement Unions also fit!
