So yesterday, in between looking at all those lovely dog pictures of Betta Maniac's, DK was on the run.
The leak frogs went off THREE times.
The first time, after the morning cycle, DK was muttering to herself about the immaculate conception, about how the HECK could water be on the floor when nothing above it was wet, and there was no discernable leak??
She mopped up, ran the towels through the wash and dry, and then gathered her flu-ridden assistant to run a dummy cycle and look for the water springing forth.
Normally, cycles are 16 minutes nowadays, so we ran one for about 10, just to be sure. NO WATER, NO LEAKS.
Turn the system back on "auto," wait for the next cycle.
Next cycle, frog is chirping, AGAIN.
DK runs down there, and discovers the problem.
Not one she'd EVER have anticipated. She tells all y'all all (WHERE ELSE can y'get such quality prose as "all y'all all"??!!)
the time to anticipate and PLAN FOR every failure, but it's the ones that we DON'T anticipate that are buggers.
So... what happened, with frog chirping #2??
The tanks drain by overflow, all of them, into main PVC pipe "sewer" drainage pipes which converge and empty into one of two sump basins, depending on which side of the room the tanks are.
The sewer drainage pipes are large enough bore that they should not EVER clog.
Oh, yes. BUUUUUUUUUUUUUUUT.
One of the sewer pipes, when it enters the sump basin, was directed through some discharge hose
, to the bottom of the basin (for the heat exchanger). The discharge hose then had a smaller bore, still not too small, though, and DK had purposely put into the center of the discharge hose a piece of stiff hose, so that the discharge hose (which is flimsy) could not ever be squashed off.
So far, so good.
But here's the thing.
As the discharge hose left the sewer pipe, it took an angle to head toward the bottom of the sump basin. This angle involved folds and bends of the discharge hose. There was still plenty of open space, DK thought.
There should be NOTHING but water draining from the overflows, she thought, and an occasional shrimp that insists on climbing into the overflow to get swept downstream.
BUUUUUUUUUUUUUUUT, she forgot about those pesky MTS.
She found the wrinkles of the discharge hose filled with pebbles, so she thought, until she opened it up and realized it was MTS (malaysian trumpet snails, that is). They had clogged the line enough so that her main sewer pipe drainage rate slowed and began to back up, at about 15 minutes into the cycle.
Upstream, where the overflow pipes entered the sewer pipe, when the water level backed all the way up there, it came oozing out and dripped down onto the floor, such that you could not see where it came from, only could see the water on the floor.
BUT DK is persistent, and found the problem. Took apart the sump pit assembly and did a little plumbing adjustment and got rid of the problem, so it can't happen again. While she was in there, she visited and greeted her sump pit underground shrimp, but she did not bother to net them out as she was short of time and they are like feral street children, very hard to catch and they manage on their own in their harsh underground world.
All fixed, she thought.
She gathered the wet towels, ran wash and dry, and sat down to rest.
Later, the frogs chirped AGAIN. This time, the cycle is NOT running.
She looks around for the water, then looks for the source, and this time it was a loose connection to an overflow that had been knocked loose when she was wrangling with the sewer pipe. Tightened that connection back up, and then she declared:
It's time to get serious about the DK Watersnake.
The parts and plans have been sitting down there a year, and she hasn't installed the thing yet.
But now, it's time. That, and Shrimptern 0.0 is returning in a week or so. Hmmmmmmmmm... a convergence of events that suggests a solution...
Her leak frogs
are cute, but annoying when they chirp!
OK, so here's a shot of the culprit, after most of the debris was cleared.
And a shot of her Aquavac harvest from the 65 gallon cleaning, about half gallon of solid mulm paste settled out.
