Pulling the pump isn't easy. Unfortuantely it was plumbed (is that the right
word?) in to the pipe line and not with a cupling that you just unscrew
Pulling to pump out means draining the pond and sawing the pipe.
I can't imagine what is blocking the flow. One time, before we put this
gutter guard around the pump, a large goldfish got sucked in, went thru' the
pressurized filter and came shooting out at the top of the waterfall. Poor
guy died about 5 mins. after his trip. That is when we discovered that there
wasn't any screening or anything. So we improvised a basket around the pump
using gutter guards bent into a box shape. No more fish taking a trip up the
falls.
We will play around with it some more when the water settles some. We can
not see a thing now. Meanwhile I am pretty bummed out not knowing for sure
that it is just an obstruction. It sure seems like it might be since we are
did get more water volume/flow out that before we started clearing things
out. Like I said before if the pump itself was having problems it still
would have the same problem even after clearing out rocks. Right?

It is kinda protected. It has a lot of rocks around it, the suction hole

on the bottom of the pump not the kind that sticks out the side, it has a

have
moved a lot of rocks around it, we were unable to get fully under the pump
but thought maybe it was cleared enough. We plugged in the pump and it has
more water volume than before but not where it should be. The pressurized
filter usually reads just under 5 psi, when we plugged it back in just now
it read just a little over 3 psi. Prior to clearing somethings around it
it
read barely 2 psi. So we are on the right track I think just didn't get it
all maybe. I don't know In the meantime the pipe that comes to the top
of the filter has a sprung a pin whole leak so we need to fix that. So we
have the pump off until we can get in there a clear more rocks and repair
the pin whole leak. BTW while we had the filter apart we sprayed water
thru'
the pipe back into the pump to hopefully push out what ever may be there.
Our pump is a sump pump and is suppose to handle solids up to 2".

If you have to pull the pump out, and I'd suggest you do. Clear the area
around the impeller. Then put the pump in something like this:

Even though the pump can handle solids, a 2" rock, snail shell or fish
parts could clog it or slow it down. The mesh baskets give lots of surface
area. I've had the lily pond one done like this for 2-3 years now, and
haven't had a need to pull it out of the pond. ~ jan
