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.

  • 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

BREAKING NEWS July 2018: We have just been informed that 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:

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:



Dual Union 3" CVA Check Valve (#29098) is ideal for larger installations that use large pumps and filters.

  • 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

Customer Question:

Is the Walking Collar on the original Aquascape Check Valve compatible with the Male Thread on the new #48026 Dual Union Check Valve

Aquascape Answer:

The old collar is not compatible with the collar on the 2.0 check valve


PondMeister Note 8/7/18: Some customers reported the Walking Collar and the Male thread it threads on to becoming stripped if you try to tighten. Here is Aquascape's responese: "There was a little “slop in the threads that was allowing people to cross thread the collar without even realizing it sometimes. We have since fixed the valve body and the collars and replaced 100% of our inventory. Odds our the stock you had is old, unless it just shipped directly from us recently. Tech can send you out new valves, since we aren’t sure if it was the valve body or collar that was compromised." Please contact Aquascape directly at 866-877-6637 or ThePondOutlet if you bought it from us and Aquascape will replace at No Charge.
