Dual Union Check Valve 2.0 by Aquascape, MPN 48023

Aquascape has re-designed their standard Check Valve.

 This will fit and replace ALL Aquascape 2" Check Valves
for all their newer pumps, skimmers and vaults. 

The AquascapePRO Dual Union Check Valve 2.0 provides a professional pump
 and plumbing connection inside skimmer filter systems, as well as Pondless® Water Vaults.

The heavy-duty, swing-style check valve flapper maximizes water flow through the valve when open,
 while preventing the backflow of water when the pump is shut off or during a power outage.

Union connections on both sides of the valve make pump and filter maintenance quick and easy
 without the use of tools.

A set of innovative reversible fittings take the guesswork out of finding the right pump or filter fitting
and allows the extension of valve height for taller filter applications, making this a truly
universal check valve designed for water features.

Aquascape has discontinued and is completely out-of-stock forever for the #29703
Elbows for replacing the old Check Valves. Aquascape's Dual Union Check Valve 2.0 #48026
introduced in 2017 seamlessly replaces the original Aquascape Check Valves in the Signature
Series Skimmers (the ones with the big black plastic half-moon shaped debris baskets)
 by simply removing all the plumbing parts from the old Check Valve and using all
 the parts that come with the new Check Valve.

As for the Classic Series Skimmers (Skimmers with the debris net with 2 metal rods -
one straight rod that goes across the back and a U-Shaped rod that snaps around the opening)
and the Pondless Waterfalls, Aquascape has provided us with the video below to explain the
 conversion to the new Check Valve #48026:
