Yes. It's green. I left it to go fallow over the winter, and it was
a mighty warm winter this year here in the Silicon Valley.
While I "could" filter out the green, it's easier on the pumps and
cloth filters if I just dump the water in the yard, and refill with
my rather hard well water (which is almost perfect for pools for
its high calcium levels).
Where I live, the water table is 400 feet below grade (at least
that is how deep my main well is dug) so I'm not worried too much
about the pool floating.
I am a little worried about the plaster drying out, so, that's why
I'd like to get it empty as soon as possible.
Maybe you should have turned that pool into the algae growth chamber for an
alternative diesel fuel plant. Looks like you had a good start.
After seeing all the yucky pictures, I hope you post one of your gleaming
"new" pool once filled up and the way you want it.
Heh heh ...
I had trouble with the math of doubling the girth because I
had (erroneously) thought that by halving the diameter from
1.5 inches to 3/4 inch, I would drop the flow to a fourth.
But, looking this up, *the flow actually drops to 1/16th!*
Coupling that with the doubling of the length from 50
feet of vacuum tubing to 100 feet of garden hose halves that
still - which means it's 1/32nd of the flow it was:
No wonder the pool is taking TREMENDOUSLY longer to drain with the
puny 100 foot 3/4" garden hose than it did with the 50 feet of 1.5"
diameter pool vacuum hose.
Notice, from the static stains in this picture, that the level
only dropped a couple of feet in the past 24 hours:

My pool has a cloth filter so we never use the flat backwash hose:

The pool does not have a vacuum (it's supposedly self cleaning); but the
vacuum hose I am using to siphon the water out is this rigid stuff:

You can see the blue pool vacuum hose in the top of this picture,
taken just now, after I hosed down some of the exposed crud from
the overnight siphoning:

I only belatedly understood what you were saying.
Up until now, I was "draining" the water out at the filter
pump; but that only got me to a half-empty pool. What you're
saying makes sense - in that I could *PUMP* the water out,
from the main drain, which is in the deep end of the pool.
My skimmers are where this pool differs from most.
My skimmers are not filtered. They have their own pump,
but, the water simply goes from the top surface of the
pool into the skimmers, and then to the skimmer pump,
and then back out through the cleaning heads on the
bottom of the pool. Note that this water does not go
through the main filter. This water is unfiltered.
Actually, in "my" pool, since the skimmers have their
own pump, the main pump won't draw air (I think) until
it exposes the three side drains (at least two of which
are companions to the bottom drains for safety reasons).
So, I think, if I understand your innovative suggestion,
all I need to do is block two of the three wall drains
and the floor drains in the spa.
This is making sense, except, as noted, that I don't
have to plug the skimmers - but I will have to plug
the wall drains.
Yes. The three pumps (filter, spa jets, & cleaning system)
are all located halfway below the surface of the pool.
I had never thought about this before, but, the logic of
what you're suggesting makes sense. I "should" be able
to plug all the wall drains and floor drains with the
exception of the deep-end floor drain ... and ... that
should suck everything into main filter, which, I can
leave open, where the water should spill out.
Of course, there is the problem of debris being sucked
through the pipes and through the pump, clogging things

I like those expansion plugs, as they should be easier to remove
than would be a tennis ball.
But, I think, since my skimmers are not connected to the pool
drain, I think I simply need to block the wall drains, one of
which is shown in this photo of the deep end:

Is this red valve that valve you speak of?
The water goes from the three or four wall and floor drains,
to a filter canister on the deck, and from there it goes
to the filter pump (which is what has the open basket of
green water pouring out in that picture above).
From the filter pump, it goes past that red valve, and
then into the filter, and then back to the pool.

Not that it matters, but the above makes it sound like you
have two filters, one before the pump and one after. I've
never seen that. Systems I've seen the one filter is after
the pump, but then the ones I've seen have been the DE type.

Oh, I have valves. Lots and lots and lot of them.
Last I counted, I think there were more than a dozen Jandy
valves on the pool equipment.
Certainly there are some to isolate the spa from the pool.
I'll have to look at the rest, as I've forgotten what they
do offhand, but, valves I have lots of!
They make owners manuals for pools?
I have the owners manual for the pool pumps, and
another owners manual for the filter, and yet another
for the cleaning system, and yet another for the
heating system, etc.
But, the pool?
I don't think they have an owners manual.
Plus, mine is odd.
When I bought the house, years ago, I had pool guys
come to give me estimates on maintenance work, and, it
turned out that *all* of them misunderstood how the pool
At times, they were perplexed because it didn't act
the way they thought it should. It turned out that
the self-cleaning pools are all designed around the
cleaning system (which sucks, by the way ... but that's
a different topic altogether).
Here is a picture of my multitude of pumps, all of which stink:
The Craftsman pump is a half horsepower non submersible, while the
other three pumps are submersibles.
The problem is that they stink, in many ways.
They get clogged. They leak. The Craftsman pump needs to be
primed and it loses its prime all the time. The connections
are puny and prone to leak. etc.
I've pretty much given up on the portable pumps. Sigh.
I snapped this picture for you of all my pumps.
I might resort to pumping out the last few feet, since the garden
hose siphon is really sloooooooooooow (16 to 32 times slower than
the vacuum hose siphon was).
The problem, of course, with the pumps, is that they clog like
crazy, and that I have to gather up an assortment of odd fittings
and connectors to get them to hook to a basic garden hose.
Plus, the darn things float around. They don't stay put in
the water. What's with that? Shouldn't these things stay put
when they're under the water and not float around?
Here's my assortment of connections I'm still trying out ...
I thought it was interesting that the blue "glue" didn't work,
since it is so fantastic on PVC pipe - but - the ends of those
vacuum hoses are not PVC so the blue "solvent" does nothing.
I am planning on getting the Fernco today, but, I really am liking
the trader4 idea of just pumping out the crud after plugging the
wall drains and the spa floor drains.

Heh heh ... I "should" play smart and say that I didn't try sucking

No go. Not even close. It's impossible. At least for me.
What I did, with an assistant, to get the siphons started, was
fill the hose with water on the deck, and then I climbed down
on the outlet end, and yelled to my assistant to drop the inlet
end into the water, and then I removed my hand from the outlet
end, and, as long as there were no leaks at the fittings, the
water gushed forth.
This works just fine to start the siphon going, but, the problem
I have is that I don't have a long enough length of the 1.5-inch
wide vacuum hose, and my connection for two hoses is not air tight.
Yeah, and I don't think that spiral hose will ever be airtight.
That's why I mentioned the clear hose.
But if you're draining the pool because of algae in the pool,
I think you're taking the wrong approach.
Fill it up, use liquid bleach.
Since you appear to have it mostly drained, put in the
bleach, then fill it up.
Next year, cover the pool at the end of the season.
Using a pump to drain the pool is very sensible
if you really have to drain a pool.

I live in NJ, so the conditions are going to be different
than in CA, but every year I've had the pool cover on, the
pool always had a reasonable amount of algae and was a mess
that took several days to get straightened out. It wasn't nearly
as bad as Danny's but it was green and you couldn't see the
botttom. And it took a lot of chlorine to straighten out. This year,
as an experiment and because it's nicer to look at water than
a cover, I winterized it, but didn't put the cover on.
About once a month, I did scoup up some of the leaves that had
accumulated in spots on the bottom. It was clear the whole time.
I started the pool back up last week and the polaris
had 90% of the debris out in just a few hours. In prior years
I'd do several backwashes before it was clean. This year, no
backwash yet. So, I'm re-thinking the whole strategy of using
a cover. It's also quite a bit of work putting it on, taking
it off, folding it up, dragging it to where it gets stored, etc.

Here's what's going to happen. After a spell of cold weather, your pool water will be at 33 F.
But you'll get that one warm spring day, an unseasonal 80 . And you had friends over to grill, (well don't grill the friends, grill steaks FOR the friends), and one too many beers, and the water looks so inviting you just have to jump in.
After that you'll never leave the cover off again, if you even survive.
