Ask your dealer for part # 72228 (Ozonator Tubing Kit), I believe it comes with the check valve and new tubing with clamps. Be careful when you pull the tubing off of the ozonator nipple or you will break the nipple off. The tubing will then go high up into the cabinet, make 2 loops, and come back down to join into the ozone injector. It is important to make sure you do this with the replacement tubing to help stop any backflow if your valve fails.
