If you have a spa or water feature chances are you have some type of Check Valve installed on your plumbing. Check valves are used when you want to prohibit water from flowing backwards. In the case where there is a body of water sitting above the plumbing (ie. spa), gravity will force water to flow backwards towards the lowest point. In this scenario, a check valve is used to suspend the water and stop water from moving in the wrong direction.
There are several different manufactures for check valves including Jandy, Pentair, Hayward, etc. However the overwhelming majority of valves we see in the field are Jandy and Ortega (Pentair) check valves. We’ve covered Jandy Check Valves extensively in other posts but today we are discussion is focused on Ortega Check Valves.
The typical indicator for repair is often seen with the (a) water level in the spa dropping 1-2′ or a water feature pump is unable to prime (fill with water). There are two parts that need to be replaced on occasion for this particular check valve.
The Spring (see #3) comes in either 1 or 3 lb options. Typically replacing with a 3 lb. spring will be sufficient.
The Seat Assembly (see #2) depends on the size of the plumbing and will be either 1.5″ or 2.0″. The picture demonstrates signs of wear around the edges due to the constant rubbing between the internal valve housing.
REPAIRING THE ORTEGA CHECK VALVE
Repairing the Ortega Check Valve is easy because it requires no tools. However if Hercules tightened the SCREW CAP (see #5) on the installation you may need a pair of pump pliers (adjustable) to loosen. Screw the cap to the LEFT and inside you’ll find a small O-RING (see #4) and the aforementioned spring (see #3). Behind the spring is the Seat Assembly (see #2).
Simply replace one or both items and hand tighten. By the way, take a close look at the O-Ring to see if there are visible signs of wear. Replacing is simple and don’t forget to lubricate the O-Ring before assembling check valve.
This is a simple project that should take you less than 3 minutes to complete.Vaughn Berger Red Square Pools Las Vegas, NV (702) 530-7331
