Product Description

2021:  DEL Ozone upgraded their 7-1140-01 Ozone Supply Check Valve to more ozone-resistant materials which means higher protection against water back-up failure.

7-1140-01 Ozone Supply Check Valve Specifications:

  • Is White (previously White / Green)
  • Cracking pressure of 1/2 PSI
  • SINGLE-barbed to fit 1/4" Ozone Supply Tubing (previously, the 7-1140-01 was double-barbed to also fit 3/8")
  • If you have a Sundance Spa made from 2008-2011, two 7-4012 check valves may be a better choice than the 7-1140-01

The 7-1140-01 Ozone Supply Check Valve is used in the following DEL Ozone Products:

  • All Spa Ozonators EXCEPT DEL's new Spa Ozone Generator which has a built-in Check Valve (not yet on our site as replacement part)
  • Spa Solar Eclipse Ozone + UV Germicidal Ozone Generator - We no longer sell
  • Total Eclipse NEXT GENERATION Pool Ozone Generators - DISCONTINUED
  • Aquaclipse Ozone Well Water Purification System - DISCONTINUED

  1. New check valve installed July 1st just had to put the 2nd one in today 1 Star Review

    Posted by on 3rd Sep 2022

    I installed 2 of 2 I had purchased of the new & improved 7-1140-01 check valves.I installed the 1st one in July of 2022, went out to check my swim spa and it was leaking into my ozonator. I will order 1 more of the new and improved. but will order 2 additional check valves made for the pool 7-1140-07 and try those out if this new and improved one leaks again, I normally change them once a year with no issues until last year.Hopefully one will work ! Ozonators aren't cheap for a 2000 gallon swim Spa.

    9/5/22: Uh oh! I will forward this message over to DEL's Technical Support folks! Thank you for letting us know. JE

    This check valve works well as intended. I just replaced one that lasted about 1.5 yrs before becoming blocked. Just buy several to have them on hand.
    I appreciate the handwritten note as well!

  4. Smart Design, Great Service 5 Star Review

    Posted by on 16th Dec 2016

    Designing the check valve double barbed on both ends takes the guesswork out of the ordering process. Plugged it in, turned it on and worked great. Got a personal hand-written note on the packing list thanking me for the order. Done with spaguts and spadepot.
