This is the water bonding fitting we have been using. We will set it in the return line (water going back to pool) rather than the suction line.
"If you were the Electrical Inspector and the EC is using a wet niche fixture with no bond lug, where would you be comfortable seeing the electrode attached to the pool equipment/ shell bond?"
The wet niche fixture has a bond lug inside and on the backside. The inside lug must be coated as well with say a 3M's Scotchcast or equivalent. Aquabond is company that makes such a product.
The attached document does not give a specific required depth for the fitting location. This has been a topic of discussion with my pool colleagues. Someone even considered placing it in a main drain in the pool bottom. My understanding for it be fully effective, it must be covered in water at all times. But these fittings are subject to corrosion and they will fail from the pool chemicals and of course, ALL my customers maintain their water chemistry
I posted the question concerning water bonding as I was told it is no longer required. This was also prompted by a posting on this forum, regarding changes for pool bonding in general covering fiberglass, vinyl and concrete. I'd have to look at the previous requirements but it looks vinyl and fiberglass builders have some new requirements.
Sorry to steer this alittle off the perimeter bond topic, but a statement by Mark Ode in his January 2020 Electrical Contractor magazine article on voltage gradients in swimming pools states this... Vinyl-lined and fiberglass pools are nonconductive materials. If the pool shell is...

I didn't see anything covering water bonding. I'm just looking for clarification.
