Spa Draining - Leak?

[ssd]

I have an elevated spa (about 18 inches above pool level) that has a waterfall into the pool. Lately, I've been running my pump in the evenings for about 5 hours (average temp is about 60). By mid-day, the spa level has dropped about 3-4 inches, to the bottom of the tile line, sometimes a bit more. Some of this is due to a slight crack in the stonework, under the waterfall, that keeps the waterfall wet as water drips from the spa into the pool. I'm not sure this is enough to account for the 3-4 inch drop (7 foot diameter spa).

Today, I went outside and the spa water level was down about 18 inches (exposing the pebble-tech plaster, not quite down to the seating level). When I went around to the equipment, I could hear the pressure relief valve on the filter (Hayward DE6000) wheezing air. When I covered the outlet with my finger, the sound stopped. I did not notice this before when trying to diagnose. Could this cause that much of a drop in water level or is there likely a more serious leak somewhere? Is it worth replacing the pressure gauge (or maybe just the o-rings) before trying something more drastic (like calling a professional)?

Bad diverter valve seals?

...That or a spa bypass check valve that is giving up, or has debris in it. Is the manufacturer Ortega? They are rebuild able as are Jandy or Pentair.

My diverter valve is a Hayward Selecta-Flo SP0740DE and all of my other valves are Jandy (Never Lube?). Today I tried to switch the actuators to spa mode to see if it would still drain. I ended up with DE coming into the pool, so I switched back and turned the pump back on to clean it out. Then I noticed water leaking from the diverter valve (the Hayward Selecta Flo one) -- all around the outside of it in a steady drip (had not seen this before). I'm guessing a seal or o-ring inside it is bad. Is this something that I can replace myself (not sure how to get the selector handle off...)? And would it be the cause of my spa draining?

Thanks for your help!

I replaced the check valve yesterday and that appears to have solved the spa draining problem. Thanks! Hopefully this will help someone else with the same problem. Replacement was very easy.

My backwash valve is still seeping water so I'll have to address that separately (probably the O-ring, but I have to find one before I can replace it). I tightened all the screws and it helped a little.

There is no set rule and it will vary with the season. Usually, every 1-2 weeks or when the pressure rises to the point where the water flow has diminished. Use a garden hose and spray the cartridge from the top down and it is being rotated on one end. Simple enough, but a little on the wet side. 70-680 exam questions Depending on water chemistry the cartridge should be soaked in diluted acid or chlorine solution, according to the manufacturer's instruction. If you would like to clean the filter cartridge better and with less effort, the Blaster Automatic Filter Cartridge Cleaner is the right product. I hope this information will help. Enjoy the pool.
