*sigh*
It started again.
After my brother discovered the rag stuck in the back valve on the septic pump, he made sure to give the valve a once over. It was in good working condition – once it was no longer filled with cloth! – so everything was put back together as it was, instead of being replaced with the not-quite-what-he-wanted new parts and pieces he’d found, after much running around in the city.
Once it was all together, the pump was working great again. It now runs so quietly, I can barely hear it when I’m sitting at my computer, which is pretty much directly above it. The filter, now that the pump was working right, actually filled more than we can fill it when we prime it, with water completely filling the dome shaped cover.
With all the troubles we’ve been having, I’ve been paranoid about it, and frequently go down to check when I hear the pump running.
Which is why I was there to notice that something had changed.
The water level in the filter was dropping, ever so slowly.
Each time the pump ran, instead of filling completely, there was space in the dome, and when it stopped, the level would be a little bit lower than before.
At one point, while watching it until the pump stopped, I saw it was low enough that I decided to prime the filter again. Once I filled the filter with water and closed it up again, I saw air bubbles coming in from the inflow opening and watched the level go down. !!! I filled it again and saw the bubbles again, but the water level stayed high enough to completely cover the inflow opening.
I told my brother about it, thinking maybe we need a new O ring after all, though it did seem well sealed when I opened it to prime the filter. As we messaged each other back and forth, he said that with the filter, there’s no way another rag or large object could be blocking the back valve again. He suggested I see how it’s flowing out of the ejector and compare it to the video he’d taken when we first got it going again. The problem with that is, even though the pump takes longer to empty the tank now that it’s pumping the fluid all the way out to the ejector, in the time it would take me to bundle up and walk over there, the pump would be done emptying the tank. The alternative would be for me to play with the bypass wires on the switch and have someone turn it on manually, after I’ve already gone out to the pump, and I really don’t want to do that!
Today, after we finished our running around, I was at my computer when I heard the pump start running while my husband was in the shower.
Which is when I heard that too familiar vibrating sort of noise.
I went down stairs to check. In the filter, I could see that it was mostly drained. There was inflow, but it wasn’t enough to fill even the bottom half of the filter while the pump was running.
I stopped the pump, primed the filter, then turned the pump on again.
The filter immediately drained, but there was no inflow anymore.
!!!
Priming process repeated. Pump turned on again.
This time, while it did drain quickly again, there was enough inflow that the water level reached high enough to cover the inflow opening, but that was about it. It never completely filled. I kept watching until it stopped, and even took some video to send to my brother.
While my brother is right that there is no way something large could get through the filter and block the back valve again, something occurred to me.
When we discovered the rag stuck in the back valve and my brother cleaned that out, neither of us thought to check the pipe from the filter to the valve. There’s a short length from the filter, which was still attached to the filter, then a short pipe with an elbow at each end that joined that filter outflow pipe to the back valve. That section with the two elbows was what my brother was originally going to replace with a new brass back valve, removing the one in the pump completely. What he hadn’t been able to find was the part he wanted that would attach to the pump where the original back valve is. The closest he could find was a steel piece, which would eventually corrode, but absolutely no one had the threaded piece he needed in plastic. So he was quite happy to be able to put the original parts back on again, which meant he could also return the parts and pieces he’d bought but never used.
So while it’s possible there might be something going on at the ejector, I think it’s the back valve again. I think it’s more likely that some sort of crud inside the pipe came loose, now that the water was flowing full power again, and instead of being washed away, got stuck in the valve.
Now, in theory, I could take that section off myself and check it. The problem is, I really don’t have the right tools for the job – my brother had to use his heat gun to warm up the plastic so he could get it apart, then put it back together again, for starters.
At this point, all we can really do it keep monitoring it. If it really is just a piece of crud that came lose and got stuck in the valve, it might just eventually get washed away.
Whatever the cause is, it’s very frustrating. It was working so well, then suddenly this is happening again!
At least, with the heat tape on the ejector, we know that shouldn’t freeze up again! The pump running with low flow again could potentially cause that to happen.
*sigh*
I was really hoping we were finally done with the septic system problems!
