Carver Owners Forum

I need to replace some fittings in the red and blue pex lines going to my sinks. Lots of leaks on a boat that sat for a few years. Regular 1/2 in fittings seem too big (shark bite and such). Any suggestions?

Having similar issues, replacing old faucets. Trying to get connections right. I have the gray plastic lines that need to be connected to normal faucets. Finding the right connector is difficult.

I replaced all my faucets. Have no idea what I bought, but I bought fittings that worked on the the grey plastic lines at Ace Hardware.

Trying Flair-it next. I read somewhere those fittings work for Carver. We'll see. Open to suggestions!

Gee I don't know, I replaced some in my 1998 355 AC/MY with the plastic style shark bites (Watts) and shark bites too? The line was the clear style pex I think. These Watts and Shark bite fittings should work. The grey tubing was Quest I do believe. But then again when pex first came out I do believe they had to use a crimping type tool on the connections. Those flair it next fitting are in my boat too. The Watts style fitting require an insert so the tubing doesn't collapse, where shark bites have the insert already in the units. Even though they seem to big I do believe they should all work.

If you have the same lines as I do, this has worked for me.......if there is some slack (extra length) you can snip a 1/4" of the ends with one of those pex tubing cutters and reattach....gets to a new spot on the line......

To any of you that have that grey lines for your potable water system. Think about replacing it all with PEX or something else. Mine started with nuisance failings about 10 years ago when I would one or two little leaks each year... some fitting somewhere had cracked. Did that for a few years then replaced it all. No more leaks!

When I was researching, all that grey tubing had recalls because of leaks. They used it in a lot of homes and mobile homes and it caused a lot of damage from leaks. There was a class action lawsuit and you could get reimbursed for replacing it, but it had to be "inaccessible". On a boat with all the hatches and various access points, I didn't qualify. If you had a home and had to cut drywall to replace, you did qualify.

The fittings themselves rarely fail. What does cause problems after a while, especially with areas that get removed a lot like those at hot water heaters is the contact surface of the tubing. As mentioned above, if you cut some back, it provides a new surface for a good seal. If that doesn't work, then the cut isn't straight, there is stress on the fitting, or the fitting is bad.

I wouldn't stress too much about the Qest plumbing. Every type of plumbing will leak eventually. The key here is don't leave your pump on or the dock side water on when you're away from the boat.
