Re: water pressure regulator adjustment

The original amfa 66b inox is still available. I just remplaced the Marco pump I bought earlier and was not satisfied with, again with the original Alfa pump. So no worries.

Onderwerp: Re: [AmelYachtOwners] water pressure regulator adjustment
I gave the screw 1.5 turns in the "+" direction and our water pressure is now better than ever.

We still have the original AMFA pump, so the regulator probably makes a big difference.  When the pump dies, I'll probably replace a bunch of the fresh water system, but I'm going to keep it Amel-original as long as possible.

That's original. I don't have any info. I think I would eliminate it, although it would be convenient to keep the pressure gauge. I think modern pumps regulate pressure good enough.

Hi all,

Our boat has a device in the fresh water system just after the pump (photos attached) that I think is a pressure regulator.  It reads "Caleffi Mod Dep Cartridge With Filter".  I can't find an exact match online.  There's one old thread on this list that mentions it, and the owner thought it was an aftermarket addition.  It looks like it's original on at least some hulls!

Our water pressure has been slowly dropping for a couple months.  I suspect this regulator needs adjustment, or its integrated filter needs cleaning.  Do these things go out of calibration after a while?  Does anyone know how to open it to clean the filter?  I'd rather not twist the adjustment screw until I know more about it.
