finding the right replacement fresh water pump

[raingolfer]

We have a Jabsco 31620-0292 fresh water pump in our system with an accumulator tank. I want to get prepared with a spare. This model has these specs:
4.3 gpm
12v
cut in at 10 psi

I'm in the US, and the closest model the local chandlery has is a model 31620-0092
However, it has a cut in at 20 psi
I'm concerned about the difference in the psi between the 2.

Will it be an issue?

I would think that the important figure is the cut out pressure, a higher cut in pressure will only mean that the pump starts a little quicker than the old one but if the cut out pressure is significantly higher on the new one there may be problems appear with the plumbing.
In short, I don't think you will have any problems at all.

My understanding is that the new pump will cycle more often, but you will have a more consistent water pressure.

Thanks everyone for the replies. I found those ones listed on eBay plus another online vendor in the US that has the same pump model I have now.




I'm not keen on upping the psi in my plumbing, so plan to stay with this model.

And I've seen a lot of European online vendors that carry this model. I'm wondering if it's more common for lower psi on Euro built boats.
