Pressure wash-down connect

[ebb]

New found Metals has their 'Wash Down Quick Connect" on a 30 day fall special:
List $69.95.
On sale at $39.95.
Engages and disengages under full pressure with no back spray.

Have an anchor wash for the foredeck using both fresh water from the boat's tank and/or environmental water. Knock the mud off the chain coming aboard with salt water, rinse with fresh to stow below. Often see the hose as self-coiling housed in a canister or in the deck under an access plate.

Imagine a quick connect in the cockpit. Again it's possible to have a single pump dual water setup for showering and laundry: wash with salt, rinse with fresh. I have a DIY download from a guy who shares his switching method. Maybe there is a way to flush the OB with fresh, or maybe even the inboard's cooling system.

This quick connect will allow you to connect or disconnect to a bulkhead or deck fitting with water under pressure coming from either direction - into or out of the fitting. That is the fitting can be used for a shower or foredeck spray - water out. Or used for water in, tank filling, engine flushing, from the dock.

A demo video shows the on/off control at the quick connect in the form of a small ball valve - while the business end has the nozzle. On the NFM site there is a YouTube info-video starring the owner of NFM and his Quick Connect. Gotta check it out.

I would like to see how a single pump salt and fresh water washdown would be plumbed? Anybody?
On the Ariel it might be possible to install a single flush mount halfway between the cockpit and the foredeck. Two stations seem more sensible. But could have the same single pump system but with a distinct valve separating the foredeck from the cockpit water. Seldom will you be showering while hauling in the anchor!
Anybody have some ideas?
Heard good things about Shurflo pumps.

Salt water.
corrodes boat finishes, gel coat, stainless, window glass and OB's.
Dry crystals are hydroscopic and attract moisture,
they condense water out of the atmosphere,
and when dew forms on dried salt it becomes.... salt water.
Salt water damp is always clammy.
Dry crystals are abrasive

NFM fitting has a 2 7/8"D polished top with 'washdown' incised into it.
It a substantial all stainless two piece casting with the valve body 1 3/4"D. Impressive clean casting - unmarked as to alloy.
Prominent patent number on the neck and a female 1/2" NPT opening in the bottom. About 3 3/8" deep under the flange.

The hose connect side appears to be a dense blue filled nylon with two O rings that engages a blue counterpart inside the stainless fitting. Has a 1 1/16" male hose thread end.

Inside the connector there is an anti backflow device in three small pieces including a spring. You have to have these pieces captured with the small ball valve fitting - that you see in the NFM YouTube video - otherwise they will fall right out. Behind the valve you'd have the hose. Awkward and a bit of a problem - NFM should have supplied a keeper (if you don't want a ball valve there) or the ball valve as an option - so that if the hose is removed you don't have little pieces popping out to get lost.

When disconnected from the flange fitting the O-rings ion the blue connect will be exposed, but are deeply seated in grooves.

There is an almost after-thought cover that swings over the exposed hole in the flange top. While the flange itself seems not to be a toe stubber, the exposed cover could be. The cover won't keep mud or sand out. And it will be very difficult if not impossible to get the opening clean to insert the hose piece if mounted horizontally.

Imco this washdown fitting has to be mounted on a bulkhead, on a vertical surface only. I would NOT put this fitting into a deck. That limits its versatility some.

BUT the fitting is worth $40, fer sure!

Mr no-it-all here is wondering if the current sale is an attempt to clear the shelves for an upgraded model.
The 3-piece backflow device needs to be kept inside the throat of the connector perhaps with a simple turn-in washer. Something that will keep the pieces available to be removed but simply held in.
The after-thought cover could be merely a different material like a soft rubber plug that would positively keep stuff out of the fitting when deck mounted.
