A syringe over the output of the pump

[neilanh]

Alright, got the new pumps in. Mini-jet 606.

I have 4 different size syringes, all of them are larger than the diameter of the outlet on the pump.

I must be a little dense, but where does one search for more of these in different sizes?

I have a 6ml syringe on mine. Not sure what the diameter is. It was one that I had. Maybe some silicone around it to seal it?

I just went to Harris Teeters' pharmacy and asked for a spare syringe,
the kind that they supply with infant medicines - they gave me two
different sizes - one of them fit like a glove - OJ style - a little tight,
but it fit

Thanks for the tip. I went around a few places today acquiring syringes, but none of them fit.

I found a piece of tubing to adapt the barb on the pump to the syringe. Looks like it should work like a champ.

I have another question (am I irritating you yet?)

I ran a few canister fulls of water through, to find out the low point where it wouldn't push anymore. THe low point is just barely under 1/2 of the canister, meaning there's almost 1.5L of water left it can't push. I assume this is limited by the size of the pump, is that correct? Should I have gotten bigger pumps than the 606s?

[Ghazanfar Ghori]

That doesn't sound right. Lower the head by a foot and see if that makes
a difference.

[neilanh]

I'll give that a run when I change them out next week. I was very surprised too.

I am lifting to almost 50" of head height though.

[maddog10]

50" may be too much. Easy way to check is to just lift it up while it is running and see if it pumps more fluid.

[Jeff120]

Just raise the containers up the difference. That should get you going
