Another update, I received the pair of diverter valves from Amazon ($32 total) and carefully compared them for size since there are differences, but the valves fit without modification in my 2-2.5" Jandy valves (my valves have 2" pvc fitting directly into all 3 sides of the valve. Differences...

Followup for future - Applying lube reduced the leakage by about 50% overnight, so I'm confident this is the source of the leakage. I just ordered the cheapest version of the part from Amazon called "ATIE Neverlube Diverter Valve Kit 4720 Replacement for Zodiac Jandy 2 Port or 3 Port Never...

Jim, I bought the house in 2001 with the pool already installed for maybe 2-3 years. I've never needed to replace the diverter myself, so it's likely that they are original. I did end up applying a liberal amount of lube to the inside of the diverter box and to the moving part and reassembled...

Jim - not surprisingly the spa level dropped as it has been, so more evidence the leak is not through the spa feature. Removed the diverter valve, there is no debris and no visible damage to the blue o-ring, but I suspect it's compressed. I measured it with a set of calipers at the 4 corners...

The funny looking black device with grey top is a check valve. The flow arrow on the clear cover is pointing vertically up and towards the return valve. I've replaced the guts a few years back and didn't solve this issue. So to summarize at this point, the current best theory is: The 3-way...

Jim, With the pump running in pool mode I just let the spa refill again and then closed valve on the spa water feature (pump still running) and as expected the spillover mostly stops. But there is a small amount that still spills over. As I mentioned these valves don't turn easily and not to...

I attached several photos that might help. The spa spillover happens from the 'spa water feature' and is 1.5" PVC line that runs from pool equipment to the very bottom/center of the spa. A vertical threaded PVC pipe can be added to it to make a kind of bubbling fountain that returns to the spa...

Hi Jim, I also have the spa water feature to return water to the spa, and I normally leave it wide open. I think this is okay since if any future homeowner of this pool wants less water they can simply close the manual valve some/mostly. Not sure what you mean by offset the automated return...

Hi folks, I've read some old posts on this issue and don't fully understand my setup. TLDR - Where are my check valves? Why doesn't water flow from 'spa water feature' immediately to 'pool return'? Should I be opening either/both the black powered valves to inspect/repair? Problem - Raised spa...

Success !! The new motor (2.6 total hp) has been running a few hours now and the max temp I measure (case, around center of label) is 170F. With the smaller motor it reached 200F after about 30 mins, which is when I turned it off. The larger motor cost me about $370 vs $230. Thanks for the...

Awesome @JamesW Last question, there isn't an exact 2.4 THP rated motor, I can move up to 2.25 or 2.6. The cost difference is minor, so I'm thinking that the 2.6 would be preferable (and it's in stock). My preference is to move up to the 2.6 (thinking it will run cooler over all)...

Thanks @JamesW and @kadavis I'm reluctant to put a smaller impeller in because I'd have less powerful jets in the hot tub. Is there any reason to think that replacing the 48 sqft DE filter with the 60 sqft should be a factor in this? Seems to me that a larger filter should always be easier to...

Installed a new US Motor today to replace a 4year old motor that failed (smoke got out). I'm wondering about two things (and see my NOTE below about the filter replacement) 1) is the mismatch in total HP between pump and (both) old and new motors okay? I'm told the new motor is a direct...
