Check Valves

Air Check Valve, Hot Spring Grandee, '89-'93

This one way check valve was used in the Hot Spring Grandee from 1989-1993 for the Jet Stream Jet air intake. All jets in a Hot Spring have both an air and water mixture. If someone put there finger in a jet nozzle and restricted the water flow, water could then back flow through the air lines and pour into the equipment compartment. This could short out equipment and/or siphon out the entire spa. Click on the "More Info" button for details.

Check Valve (Air)

Air check valve for all 1993-2001 Hot Spring, 1997-2000 Tiger River and 1997-2002 Hot Spot spa models. This check valve is located in the equipment compartment under the bartop. Its primary function is to prevent water from back flowing into the equipment compartment should a hydrotherapy jet become obstructed (like when a guest sticks their finger in the jet).

Note: These check valves age at the same rate. It is best to replace all of them at the same time if budget allows

Check Valve (Ozone) Freshwater I

OBSOLETE USE 1044101
This 3/16" OD check valve was used on the original exterior wall mounted Freshwater Ozonator. It was positioned just after the injector. Its purpose was to prevent the spa from siphoning out through the Kynar tubing in the unlikely event the spa's power was interrupted and the wall mounted Freshwater Ozonator was mounted below the waterline.

Check Valve (Ozone) Freshwater II, 3/16"

OBSOLETE-Use part# 1044101

This 3/16" Freshwater II ozone check valve is to prevent water from back flowing into the FreshWater Ozonator if power to the spa is interrupted or the spa is placed on "Summer Mode". "Summer Mode" will shut down the Silentflo 5000 circulation pump 8 hours every day. This in turn stops the intake of ozone into the spas plumbing. Since the ozonator is below the water line of the spa, water can start to "siphon out" into the ozonator if the check valve has failed. Click on the "More Info" button for details.

Check Valve (Ozone) Freshwater Ozone, 1/4in O.D.

Over time an ozonator check valve will breakdown under the harsh conditions of ozone. Our OEM check valves have a special diaphragm (Viton) that enables them to last longer than rubber. Rubber diaphragms last about a month before the rubber becomes hard. Click on the "More Info" button for details.

Typical lifespan is 5-7 years. The larger end connects onto your existing tubing and the smaller end is designed for 1/2" inside diameter tubing (70316)

Check Valve, Safety Suction

This check valve's function is to "open" when someone puts their hand over the jet pumps suction fitting within the filter intake. This check valve will "open" drawing air into it from the equipment compartment, thereby stopping suction of the jet pump.
