Hi everyone, so I recently purchased a eshopps 1000 hob overflow box and I was curious if anyone here had them before and what kind of plumbing was used because I just purchased mines and don’t know what size pvc or how to set it up thank you so much.
 
I was curious if anyone here had them before
I have not, my only firsthand experience with a HOB overflow was with a CPR brand unit…

don’t know what size pvc
Eshopps own website, as well as various retailers describe this particular model as having “two 1 inch bulkheads”, so you’ll need to use 1” PVC fittings, at least to connect to this overflow’s included plumbing!


how to set it up
None of the retailers of this product even list if it’s included bulkheads are slip, or NPT (threaded), nor do they list the bulkhead’s material of construction…

This said, I’d assume it’s slip, and that you’ll need “all purpose pipe cement” (vs. pipe cement specific to PVC plastic only)…

This overflow does have two drains, and one does appear to have a shorter standpipe, so I think it’s also reasonable to assume it’s intended for a “Herbie” drain configuration… (I would recommend looking up a few photos of how this is arranged)

Basically, you’ll want to plumb this in 1” rigid PVC pipe, or possibly 1” tubing if lower maximum flow rate is acceptable!
 
The ESHOPPS HOB Overflow I've used in the past I used flexible tubing on. I want to say it was 1.25" ID tubing but you'd want to measure the outside diameter of the bulkhead fitting and use that as you inside diameter of the tubing.

If it's 1" PVC bulkhead it's likely going to be larger than 1.25" tubing to fit - probably closer to 1.5" or slightly larger even.

However, it looks like yours is designed for PVC, not tubing, so using tubing is probably not the best idea. Tubing connectors will be ribbed on the outside to give something to hold onto.
