Default March Pump losing prime

I just started three tier fly sparging and attempted to pump my sparge water from my keggle to my coleman cooler that was about 6 feet above the level of my pump. I could get a great prime, but I would lose it after about 20 seconds. I ended up having to move the cooler down to floor level to retain the prime... I'm at a total loss as I had zero problems getting an initial prime, but constantly losing it was really disappointing.

sounds like a fitting is slightly loose. try taping all joints with teflon pipe tape.

I am using QDs from mcmaster and all fittings are wrapped with teflon tape, but I will double check... should this pump be able to pump into a vessel 6 feet above?

yup 6 ft is doable albite slowly as it just about it's max head height



edit: if you have a pump why going so high? a pump enables you to cut a tier out of your system. my pump is on the floor with my hlt and kettle at 6 inches and the mt at 28 inches.

so you use your pump to pull the wort from the mlt to the boil kettle? you basically match the speed of the sparge to the speed of the pump?

That's what I do. I have a three tier and use the pump to vorlouf and after vorloufing I pump from the lauter to the kettle. I have an valve on the outlet of the pump to control the speed.

so MLT and kettle are on the floor and HLT is above so it can gravity drain to MLT for the fly sparge?

HLT on top so it can gravity, MLT in the middle, Kettle on bottom. I just pump, cause I'm too lazy to disconnect the hose after vorloufing.

sorry p ump to fly sparge, i find it easier to match outflow speed to inflow this way. plus with my hlt at waist high it's easy to add in water
