Default Water pump PSI

Anyone know the output pressure from our fresh water pump?

I want to install a under sink filter, and it requires at least 25psi. Does not seem like a lot, but wondering if anyone knew if that filter would work with our pump?

Highly unlikely you have the original fresh water tank pump. There are different options for replacement, but the one mentioned most frequently is the gowesty.com Comet one for about $30. If you enlarge the photo, it looks like it says 1,1 bar??? which converts to 16 psi.

There are other Comet fresh water pumps available in Europe which may have higher psi. Whale is another brand.

For example,

Thanks OldWest.

Looks like Whale makes one up to 1.4bar (20psi). Might be as good as possible with these submersible pumps....

I do believe we have the Comet pump in our van, but don't think 16psi will push through a 25psi filter.... As I make some progress will pass along the results.

If you can't find a replacement submersible pump and really want that water filter, can switch to a non-submersible pump like Discus:

Less work:

I use the Camco Taste Pure 2-pack water filters at Walmart when filling fresh water tank.

On sale right now for $17.64: https://www.walmart.com/ip/TastePURE...arbon/14504322

Then I buy the gallon drinking water for convenience and extra safety.

Other Westy owners use the water filtration bottles like Brita. One poster mounted his on the wall next to kitchen cabinet.

I second OldWest's idea about the Camco filters and drinking water. I do the same thing, but buy the 2.5 gallon drinking water. They are the just the right size for sticking in the storage under the rear bench seat. I add or remove the water as needed for space, but it is a perfect fit with five in there.

I have bought a lot products from Camco that turned out to be junk, but everything they make for fresh water is great. In addition to the Camco filters, I also use their drinking water hose and tank products. The water is so clear and odorless, it almost makes me want to drink it.

I always filter the water going into the tank, ebay has lots of inline filters that fit onto a water hose, I also use food grade hose.

There is a difference between the inline hose filters bringing water into the tank, and a filter at the tap for drinking purposes. I understand that for shorter trips, using gallon jugs for drinking is fine (and what we do currently). But we have long term plans to be in the camper full time in S. America, and utilizing storage space for water jugs is not ideal. We would prefer to be able to drink the water from the tap, and have it be OK.

Certainly appreciate the ideas, and for short term, I agree there are much less complicated solutions. We may end up having to replace the pump. and find a different filter cartridge that will handle 20psi. Probably add up to about $100 for the parts.

I tried to find the owner that mounted a Brita somewhere. That might be an interesting idea....
