Water pump psi

[Trailerlivin777]

Hi all!

New here. My water pump died (it was an old sureflo) my dad has a brand new freshwater diaphragm water pump but it’s rated for 160PSI. (Which is obviously too high)
I do have a brand new water pressure regulator still in the box...

My question is:
Can I hook up his 160psi water pump and use my pressure regulator to dial it in to 40psi? Or do I HAVE to buy a new water pump?

Funds are tight these days.

Thanks!!

I agree that the flow rate seems very low. I don't think I would use it but would get one like the one you already have.

Right and I understand this. But as I stated in my OP money is tight and I won’t have money to buy a new one for at least 2 weeks when my next check comes and I don’t currently have running water.

My shower head now runs at 1.5gpm max anyway.

The rated flow is 1.8 gpm vs the 3 gpm of the Sureflow pump that I have. So water flow will be low, you might have a problem with your shower flow. That sureflow is a diaphram pump too but it has a built in bypass. That pump you have seems to be designed as a sprayer pump, notice that it is not in the automotive area of amazon where the RV equipment is found.

It may work try piping it up outside the RV to the regulator and see if it works. If you are on city water do you even need a water pump?

My shower head is rated at 1.5gpm low flow if that helps.
No I have a rain/snow catchment system that runs to IBC water totes. I’m several hundred yards from my dads house I’ve got 12v solar that use for anything low power draw. And I have a 100A power pole that my dad had to run custom for me a while back.

Ok I’ll give that a try

Does your old water pump still run but does not pump water? If so it's an easy fix with ***Link Removed*** new pump head.

Pressure sure it’s completely fried or something (it was really old) it makes no noise or click or any signs of life at all.

What is the amperage draw on that 160 psi pump and is it 12V. And can that diaphragm pump deal with a cut off head, meaning it is pumping against a closed valve. Positive displacement pumps can have problems in that case.

Amperage draw is 0.8-1.5 it’s actually a 120v (I’m stationary I don’t travel at all with this trailer and regularly use a power pole next to my trailer)

I’m not sure about the other questions you asked (he bought it a few months ago for another project) I looked it up on amazon here’s the link to the exact one he has. I just need running water again until I have the money to spare on a new one.
