Shurflow Baitwell Pump

[Cpt Bob]

Hi. I had a friend install a new baitwell pump recently. My bait well pump will not suck water into the baitwell. I can hear the "humming" sound indicating that the pump is working but no water in the hose. The pump also has a hose at the top of the pump that is connected to another pump for salt water washdown and that works. Is it possible that the hoses are reversed? Thanks

The pump has a hose at the top that is connected to another pump that works.

Is this a new installation of a replacement?

Having a hard time envisioning how a centrifugal pump (bait well) would pump water through a positive displacement (wash down) pump.

I have separate intakes for each pump

Good Morning. Thanks for your reply. I am attaching some pics. Hopefully it makes sense and can help.

The left hose goes to baitwell and the top right hose goes thru a filter into the saltwater pump and out to the saltwater hose

Yes. It is a new installation of a replacement.

Ok, I have the same washdown pump on my boat.

If I’m seeing this correctly, the intact (outside water) comes into the live well pump. From there, the outlet of the live well pump is connected to a in-line strainer on the input of the washdown pump. Have to assume the exit of the washdown pump is pumped to washdown hose if that works.

With the output of the live well pump connected to the washdown pump, how is the water supposed to get in the live well?

As it’s plumbed, I don’t see how it ever worked, but check these things:

1. Pumps wired correctly. Pretty easy to wire up a DC pump backwards (reversed)

2. Make sure inlets are inlets and outlets are outlets. Mix them up and they wouldn’t pump water

Good Morning, The intake water comes via the thru hull to the live well pump from which there are 2 hoses connected to the pump. Isn't the bottom hose that is connected to the live well pump going to the live well tank and the top hose that goes to the wash down pump going to the washdown hose? The washdown pump pumps water. I am confused. There are 3 ports on the live well pump. The one at the bottom screws into the thru hull fitting and that leaves 2 ports, one at the bottom and the other at the top of the livewell pump. So you are saying one of this is the intake and the other is the output. How would water get to the live well tank then? Checked the wiring and it is wired correctly. Look forward to hearing from you. Thanks.

What live well pump do you have?

My live well pump is shown below. The bottom (intake) screws into the seacock. The output (top) is plumbed to the live well. The feed to the second pump (lower port with pipe plug) is plugged off since I have a separate intake for the washdown pump

I have a Shurflo 800. See pics. So which port goes to livewell and which goes to the washdown pump? Appreciate u helping. Do I have to replumb?

The male threads on the bottom is the inlet that screws into the seacock.

The molded hose barb at the top of the pump goes to the live well.

The nylon hose fitting on the bottom (side) is the washdown supply.

I thank you very much. I have also ordered a new pump because we tested the pump in a bucket of water this am after disconnecting the hoses and it was not sucking water thru the pump. Once the new pump arrives some time at the end of the week, I will let you know. I am convinced that you have it right that the mechanic had the hoses reversed. Thank You.

Just like indicated above

bottom thread fitting is inlet. top fitting outlet. discharge from washdown pump to the inlet of the pump is the lower hose fitting.

Heads up.....that particular pump requires a flooded intake to prime.
The pump does not "suck" per say. It will not prime sticking the end in the bucket. The pump has to be mounted below the water line or behind a scoop type intake to force water into the pump chamber for it to prime
