Removable connection added below check valves allowing you to remove pump without draining the BioFalls filter. You need a check valve assembly to hook up your pump to your plumbing.  Prevents water from draining out of your Biofalls filter. Simplifies pump removal

In 2018, Aquascape re-designed their standard Check Valve. 

Dual Union Check Valve 2.0 #48026 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.

• Connects the pump to water feature plumbing
• Innovative reversible fittings allow for universal application
• Prevents water backflow when the pump is not operating
• Dual-union, tool-free design makes maintenance quick and easy
• Heavy-duty swing-style check valve flapper
• Height extendable for larger filters and pumps

Fittings Included:

• 2 - Reversible 2" MPT x 2" Slip
• 1 - Reversible 1.5" FPT x 2" Slip
• 1 - 2" Check Valve Elbow

July 2018: Aquascape  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 snmaps 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:

Please watch the video below:

(In the short run, you may want to just remove the Check Valve altogether or cut out the flapper from the failed Check Valve using a hacksaw blade wrapped in a towel and a pair of needle-nosed pliers)

This is an example of how to use 2 of the fittings to adapt the bottom of the check valve. The 3rd fitting will be used for the top connection. Please see the Image below:
