Frequently Asked Questions

Is this the same as a standard bulkhead fitting?

The tub outlet fitting serves a similar function to a bulkhead fitting but is specifically designed for the Hydro Flow Ebb & Flow system, for consistent compatibility across Hydro Flow components. Use the tub outlet fitting when you want that guaranteed match with other Hydro Flow parts.

What hole size do I need for installation?

Refer to the Hydro Flow product specification for the correct hole diameter for this 3/4in tub outlet fitting. Drilling to the exact spec keeps the gasket seal watertight once installed.

Does this fitting include a gasket?

Confirm gasket inclusion with the product specification. Hydro Flow tub fittings typically include the necessary gasket for wall sealing.

When should I add an extension fitting to this outlet?

Add an extension when the base tub outlet fitting doesn't reach far enough for your table wall thickness or media depth. That's simpler than swapping in a different outlet fitting entirely.

Can I use an extension fitting with this outlet?

Yes — Hydro Flow extension fittings are designed to pair directly with this tub outlet fitting for added length when needed. Multiple extensions can also be threaded together for even greater reach.
