Will do! Once I'm allowed back.

I would think the shore water inlet for that vintage has both a built in check valve and regulator. Hopefully it was winterized properly but even when it is, it's not uncommon for those units to fail come Spring time.

I've been doing the winterization the same way every year, Using small air compressor to blow out the system.

When the boat was winterized, if antifreeze was not pumped through the dock water inlet, the check valve / regulator most likely froze and was damaged. Time for a new one.

When I changed mine out last year I opted for a unit that had no regulator, only a check valve. Reason is those built in regulators are not serviceable not to mention they restrict water to unacceptable pressure IMHO. That being said, it is important to have a regulator due to the unacceptable high water pressure seen at many marinas. I opted for an outboard unit which is permanently attached to my dock hose. I also have one permanently attached to my "travel" hose so when connecting to other marinas I am protected. This way it becomes a serviceable part or maybe I should say replaceable part if something were to go wrong. This is the regulator I use. https://www.amazon.ca/Camco-40055-X-Bra ... 432&sr=8-8

Hans, that's the same spec as most dockside inlets with built-in regulators. Most are anywhere from 45 to 65 psi depending on the model. Some units were actually serviceable, but I don't know if any are still made that way.

I replied and it shows I did... but I don't see a message. if this shows 2 times at some point my apologies...

Most likely the inlet has a check valve / Water pressure reducer either in it or directly behind it. This type is common and they are build in. (https://cdn11.bigcommerce.com/s-6rtev5o ... 60.jpg?c=2) They can get stuck or damaged from freeze if there is still water sitting in them.

I also know someone who installed a water filter directly behind their inlet. It froze and split wide open... I assume you don't hear water or bilge alarms?

I had a Shurflo brand from the factory so I swapped it out for the same unit. Pressure was once again inadequate, same as before. Threw out an $80 new part and replaced with outboard regulator and non regulated inlet, problem solved. My best guess it the pressure I got out of the Shurflo unit was less than 35psi on a good day. https://www.westmarine.com/buy/shurflo- ... et--183725

Bought a stainless steel regulator thinking go with the best. Plugged it into the hose at the dock and nothing came out but a small trickle. They sure do not make things like they used to!

Yep I also use a external hose type pressure regulator and check only on my water inlet
