Freshwater System - PEX fittings

dtfeld said:
Thanks guys. I was hoping color was indicative, but looks like that wont work.

Part manual does in fact show 15mm. The complication is I don't think this is original Sea Ray, the water tempering valve is gone, and some PO has some weird connection between the fresh water and AC raw water systems. It's all coming out. This could be either 1/2" or 15mm depending on who did the job. I'm headed to the boat with a section of 1/2" PEX tubing and hoping these are 1/2" If not, I'll have to come up with plan B.

The fittings have the size embossed right on the side. My OEM's are white and say 15mm. The replacements I bought at our marina chandlery are black, are 15mm and otherwise look exactly the same. The marina also has 1/2 fittings the same. Black and marked 1/2".
 
Thanks guys! Mine were 15mm and there were enough fitting and pipe to make the connections I needed. I’ll probably add a few fitting, o-rings and some pipe to my spares kit.

I removed the old Jabasco accumulator that was leaking, and I replaced that with a Sea Choice that I plumbed in near the pump up front. I also removed a bunch of lines that may have been plumbed to a water maker, but that system was not present when I bought the boat.

And I’m back to a dry bilge!!!!!
 
Clean job. Well done. I had that same crappy accumulator until it split completely in half at the seam. Pumps were pumping the water tank dry when I found it. Glad I don't ever use dock water connection. I ended up just replacing the accumulator with a water pressure gauge. I have pumps that dont need an accumulator.

Just Curious...what pump doesnt need an accumulator? The accumulator I have is very small, maybe .75 l, so it doesn't do much, but all my faucets run smooth even at a trickle.
