New Gas Water Pump, won't pump.

[p_mori7]

Seeking advice please.

Earlier today, I purchased a new gas water pump.

Manufacturer BE Pressure. It has a 210cc PowerEase engine. 2.0" Inlet and outlet.

I filled with oil, filled with gas, installed the fittings for the cam lock hoses. It came with a 12' suction hose and a 50' discharge hose.

It started on the first pull, the engine runs smoothly and operated perfectly.

I filled the pump case with water, started the engine and let it run for about 2 minutes, but it will not pump out the discharge side.

I checked the hoses for obstructions (none), I removed the suction fitting and re-did the Teflon on the threads, checked the drain plug (tight), checked the rubber gasket in the female end of the hose (present and good contact).

I tried it again, not pumping. When I open the filler plug to re-prime, there its lots of foam (sucking air).

I took into the garage, pulled the fittings off, took the male flange plate off (gasket there and good contact), took the pump outer housing off (large o-ring there and good contact), pulled the turbine housing off (small o-ring there and good contact). Reinstalled everything and also added washers to the outer housing bolts and male flange plate because the bolts seemed a wee bit long and may have been bottoming out.

Tried it again...foam and no pumping...GRRRRR

I tried multiple times to restrict the discharge hose in an attempt to build prime...just foam. I don't let it go more than 2 or 3 minutes then stop the engine when it won't pump.

The strainer is only 4' below the pump, in clean pool water.

I've run out of ideas (short of returning it).

Any of you guys have any other ideas I can try tomorrow ?

Leave the priming hole open and keep dumping water in there. once it picks up, plug the hole back. I usually have a water hose and just keep running it in after a while it will take off.
You can elevate the discharge above the pump height and that will help it prime too. Keeps the water from running out and down the drain.

Thanks. I will try to elevate the discharge hose a bit more. it is already somewhat elevated over a section of the patio, but only about 10".

Yeah, you need to keep water in it until it starts its own syphon action.

What we did (when we had to use ours to fill our water tank from our transport tank when we lost our well) was have both ends (the discharge into the tank and the suction from the other tank) have a "drop", so they were both near the ground, then back up to their respective inlets/outlets, then prime the whole shebang... put the plug in THEN fire it up. Usually when the slug of inlet water makes it, it will have enough water momentum to pull water from the tank and keep it running.

Other thing - as the pump broke in, it pulled more vacuum, so it didn't tend to lose it's prime. The first few thousand gallons, tho, what a PITA!!!!

Thanks Lassen. Sounds like I need a bit more elevation on the discharge side. My water supply is below the pump. I will also try to move the pump closer to the pool to have more suction hose in the water. It will be deeper, but there will be less air between the water and the pump inlet.

Be prepared as you will likely get a shower keeping the priming hole open. I usually fill a 5 gallon bucket up and just keep pouring it in slowly until she starts pumping on her own. At which time I usually get a face full of water, but its the only way sometimes.

Well...have tried for 20 minutes again this morning...no go.

- Had elevated the discharge hose about 2'
- Moved the pump to the edge of the pool (it was only 3' further away before)
- Tried pouring water non-stop into the priming hole
- Tried restricting the discharge hose
- Tried leaving the filler plug slightly loose so air would bleed out

If I throttle back, and pull the suction hose out of the pool, I can hear air inrushing into the hose...then I immediately dump it back into the pool and refill the pump chamber.

The ***** just won't **** water.

I've rented and used these before...wanted one of my own since we may get some localized flooding...

This thing is really ******* me off.

Try elevating the discharge hose, and filling the discharge hose with water so it flows into the pump.

Those pumps can be a real pain in the nuts. When I was doing some underground plumbing work with a buddy, he would mostly kink the discharge hose in his hands, while I primed. As soon as you could feel there was a slight amount of pressure building, slowly unkink the hose while keeping pressure in the pump side of the kink. Don't fully release the hose till there is steady flow out the line and constant pressure. That was with a 5HP Honda water pump.

That being said, I have no idea how we would have done it with that pump, and just one guy on the ground.

 

[p_mori7]

Tried again.

Still not sucking.

Suspect incorrectly shimmed impeller. On a new pump.

I am done with it.

It's going back tomorrow.

I used the Briggs and the Hondas and I primed them as gdocktor3 said.
All good advice here.....sounds like u got a bad one out of the gate.
They used to make quick work out of a wet hole when I was doing production work.

The 3 inch was a monster! My Briggs (HF used to sell them) was great too.

Let us know on the new one.

Very strange indeed should easily be self priming unless your sucking up air.

My B&S powered Pacer pump primes very easily even with a long suction hose and high lift. I use it weekly during the season. I also use a foot valve to stop any drainback

Years back I had a little 2 stroke Homelight that wouldn't make a prime unless the suction line was full of water



We also had a old Hale high pressure pump at the farm a long time ago that primed by holding down a lever to close off the discharge port

A foot valve on the end of the suction will help with priming but if your pumping trashy water with it you'll have to clean the valve frequently.

Did you solve the problem? I bought a new petrol pumo and have the same problem.

In addition to priming the pump,
Raise the suction hose elevation so that the prime water can't run out.
Fold over the discharge hose to effectively limit (or stop) the water from leaving the pump.
Keep the engine's rpm low
Add additional prime water

I have some wooden blocks for my pump, so that I can keep the pump side elevated, which helps keep the prime water in the pump housing.

Thank you very much. I have folded over the discharge hore and it helped the pump to prime the water.
