I searched for this and surprisingly didn't find very much concrete information. I'm looking for a pump to move water from my faucet about 20 feet laterally and about 4 feet up into my tank for water changes. Cost and noise are more important than flow rate; I haven't seen a pump anywhere online with a flow rate that I would deem unacceptably low.

Anyone have any suggestions?

I use a submersible 1000lph pump, that I sit in a bucket with the tap running into it. We have instantaneous gas heated hot water, so I select 37 degrees C on the gas controller and then add a little cold so that the water going into the tank is at the right temperature. The furtherest tank from the tap is just over 7m. I also use the shower head, into a bucket with the same submersible pump.

I used a 500 lph pump inititally but this was too slow. I use 16mm hosing on my 1000lph, but 19mm would be better. The pump cost me $60 (New Zealand Dollars, NZD) which is approximatel $50 US. I got the pump from a place that specialises in water fountains/ponds for outdoor gardens.

Hope that helps?

Dkarc@Aol.com (Ryan) is a great person here on SD to PM and ask. He works for Aquatic Eco-Systems that sells all kinds of stuff like that and he's a lot of help. I've got a couple situations that sound just like yours and I bought Mag Drive Model 7 from Ryan and was extremely happy with it. How happy, I bought another one.

HTH,
Keith

Knowing the name of a series (Mag-Drive) to look at got me to this fantastic page that I link for future reference:

That table is excellent. I went ahead and bought a Mag-Drive 5. :) Thanks guys.

Cost being a bigger concern than flow rate I get guess I see why a model 7 is more than you might want, that wasn't the case for me. I can do 95% WCs on a 72, 55, and several 29s all in the same night so speed does matter to me. They are nice and quiet though, so there you won't go wrong. I've got the second one I got permanently in the 72 to drain it and other than the moment it kicks on the discus don't mind it at all, so it is pretty quiet. Good luck on your purchase.

Wait, out of the faucet? I'm honestly surprised your faucet doesn't have enough pressure to push that from the sink + 5 feet (lateral).

Maybe I'm not understanding this right, but how are you going to connect a pump to the faucet to do WC? Wouldn't there be a bottleneck with your faucet? So it might help to have a pump, but it's still going to be reduced by your hose ('friction') and the flow rate of your faucet and there is a practical maximum regardless of your pump.

So maybe I'm not understanding the question being posed...?

I've attempted it going from the faucet to the tank with just an ordinary siphon. It makes it through laterally and then rises about a foot (you may have misunderstood my situation; it has to travel 20 feet laterally and then about 4-5 feet up) before it equilibrates. (By the time it gets to the vertical climb the water has almost stopped moving). If I made a seal (which I didn't; my attempted setup before, now that I think about it, was a pretty silly one) I *might* get enough pressure, but I am a bit skeptical about that.

Anyway, I wasn't necessarily planning on hooking the pump directly to the faucet. More likely I'll put the pump in a container, fill the container, turn the pump on, and keep water running flowing into the container. At about 4-5 gallons per minute at this height, I should be able to keep the water level in the container roughly constant; if the faucet's a little slow I can turn the pump off occasionally. It'd certainly be easier than the setup I have now, where I lift buckets up onto a table and then siphon in. (By contrast, the setup for *removal* that I have now is just fine, with a siphon running out the nearby window.)

...I begin to suspect, now that you mention it, that a hose, preferably one of the drinking water grade ones, with a faucet adapter might be *entirely* adequate here, and that I should try that first...went ahead and tried to cancel my order for now.

My faucet isn't adaptable, but many many are. Guess I paid more attention to your run and lift than I did the fact you said you were wanting to go from a sink. I age all my water so that's probably the second reason I skimmed over the sink part, but sorry I missed that. Yea an adapter and potable water hose would certainly be cheaper. Ace Hardware here just had 25' potable water hoses on sale for $9.99, they still might be on sale.

Well I bought a hose and a faucet adapter and they work wonders. Thanks for your skepticism, ericatdallas, you saved me $60 (although my own willingness to jump right to buying a pump cost me 10 of those dollars in shipping, since they couldn't cancel my order).
