Product Description

DEL's OZONE 25/50/100 (previously known as Eclipse until 2018) for in-ground pools and spas have replaceable parts, adding an Eco-friendly touch to this great product line.

The 9-0770-01 and 9-0770-02 are the same with the exception of the 9-0770-02 has TWO Ozone Supply Check Valves for extreme cases where water backup is more likely to occur (for example when Ozonator is installed below water level).  Although the Eclipse NEXT GENERATION Manual (below) calls for 9-0770-02, this is extra precaution and DEL Ozone recommends anyone exporting to use it.  For domestic shipments, the 9-0770-01 is most commonly used.

The 9-0770-02 Replacement Ozone Check Valve Assembly gives you what you need to protect your Eclipse Pool Ozonator from water backup including: 

Before each swimming pool season:

  • Inspect Ozone Supply Tubing for cracks, hardening or yellow discoloration caused by nitric acid
  • Make sure no water is present between the Check Valve and the Ozone Generator when the pool system is in filtration mode, as this indicates Check Valve failure.  Replace Check Valve immediately to prevent water from backing up into the Eclipse
  • Make sure you have a tiny stream of ozone/air bubbles coming into your pool, or into your Mixing Degas Vessel (MDV).  If you don't, the Check Valve may be stuck shut (failed)

Warranty Information

1 year factory warranty based on purchase date (not manufacturing date). For all warranty inquiries, DEL will take care of you directly. Contact: [email protected] to receive a Return Goods Authorization number and instructions on how to send your DEL ozonator in for repair.

  1. Just what I needed 5 Star Review

    Posted by on 6th May 2021

    My check valve assembly and hose was chewed through by some critters. Bought this as a replacement and it was an exact fit. Shipping was quick and price was right. Love Your Hot Tub will be my go to vendor for pool parts going forward!!!

  2. Purchase of Ozone Generator Modules 4 Star Review

    Posted by on 9th May 2018

    The park was a replacement cell for a Del Zone ozone generator. The cells do seem to fail more rapidly than advertise. Love Your Hot Tub is quite prompt with responding to orders and helpful in directing me to a contact with Del Zone regarding a modification needed to accommodate to the use of a variable speed pump.
    I gave the module a 4 because of the short duration of the module, but the service from Love Your Hot Tub is outstanding.
