Pump to drain water

So looking to buy a pump mainly for my 24x44 hockey rink which uses about 4000 gallons. But figured I'd get one that would be good in case I never need it on my pool.

What are folks using that doesn't break the bank?

Will need about 100 foot hose as well.

Thx!

We use this one to drain down our pool when it gets too full.

100' of hose you can probably get 4 or 5 of these and connect them together.

or one of these (above pump has garden hose attachment)

All in for around $100

I reccomend the Little giant. Its flat on the bottom so it doesnt tip over easily. Has built in check valve, and removes the water to the lowest level, and shuts off automatically. better then other sump pumps.

I have a little giant. But it would take 2 days to pump out 4000 or more gallons from the rink with it. Seems to be more of a pool cover pump if it's the same one I have, was looking for something with quite a bit more oomph.

REVISION FURTHER BELOW. This hose did not work but the concept it correct.

You have a good pump - I have it too. The problem is not your pump, it's likely the hose you are using. That pump is rated for 1700/gph if using 1" I.D. tube per the manual via a 1" fitting. Using a 3/4" x 50' garden hose (which is bigger than a normal 5/8") reduces the performance to 500/gph - regular garden hose would be even less. You would need to remove the plastic adapter that is installed in that pump which reduces the fitting from 1" NPT to 3/4" GHT. Then use this 1" MNPT x 1" NPSH (same threads per in as NPT but not tapered - uses a washer). Moon 358-1061011 Brass Fire Hose Adapter, Nipple, 1" NPT Male x 1" NPSH Male: Industrial Pipe Fittings: Amazon.com: Industrial & Scientific Then I bought this flat 1" hose with 1" NPSH M and F ends. Stanios 4502-1000 Reinforced Blue PVC Lay Flat 1-Inch Water Discharge Hose with 1-Inch Threaded Couplings (25 Feet): Amazon.com: Industrial & Scientific

There are other adapter/hoses/tubing that will work but I was looking for small storage size and durability on the hose while maximizing the output of this pump.

The problem is not your pump, it's likely the hose you are using
I have the Lowe’s version of the 1/4 Home Depot pump. When using a long hose it works great but doesn’t have the power to push a lot of water. So I made my own hose using 1.5 inch sprinkler pipe and a female garden hose fitting thing. It flows like crazy. Just a solid stream of clear water with no aeration. I used about 40 ft out into the yard, a 90 fitting and another 2 ft piece of pipe. It holds itself low enough in the pool that I don’t have to babysit it.
For the hockey rink it would work even better without the riser pipe by having to overcome less gravity, if you made a 2nd hose adapter piece right to a 90.

So the little giant is fully submersible?

Will try to see if I can find that hose in Canada. If I needed to get two with a coupling.. What size coupling would I need?

Yes the Little Giant cover pump is fully submersible. I put it on our 18” deep step to drain the pool. That hose comes in longer length so you won’t need a coupler. But if you needed to couple two hose lengths it would be a 1” NPSH.

So the above was written prior to testing the pump and the flat style 1" hose. The pump doesn't have enough power to open up the flat hose I linked to. So it was a no go. So instead I bought a 1 1/4", 20' long vacuum hose (marketed as for above ground pools since it's smaller than the normal 1 1/2"). It slid over my brass adapter noted above and works like a dream. It pumps out 2-3 times faster than my 3/4" garden hose used to. And being only long, it rolls up around the pump fairly small for storage. Last night I pumped out a few inches of accumulated water like a dream. So fast in fact, that I'll have to modify where the water exits the drain system so it doesn't erode anymore. Good problem.

Have a link to the hose? Thanks for posting as I was about to get a custom lie flat 1" ID hose since I had bought the adaptor already.
