Fresh Water Plumbing

I have a 2001 Mainship 390.
Can someone tell me what the fresh water plumbing is made of and where to buy connectors ? It is clear hose/pipe. I have a cracked 90 degree fitting where one would connect a hose from shore to the fresh water system. I want to have the replacement in hand when I start to try to access it.

Thanks,

Hawk

Doesn't sound like a factory plumbing job. Try a big box store.

i was told they were PEX but i'm not sure that is true. i did buy a bunch of the end fittings but i don't remember/have any record of where. they are a type of flare. i don't find them easy to work with compared to whale.

take a look at this. may not be exact but i think it's close.

You will need to know the size tubing and then Shark Bite will most likely have something that will work.

My 2005 34T has 9mm PEX; all push fit connections. Impossible to find in the US except ebay/amazon. Get a 1/2" PEX push fit fitting from a big box. If it won't quite fit, then you know...

Sounds like pex tubing. You need to know the size of the tubing. Then check out Watts-Aqua Lock fittings. Good website with lots of options. Other option would be Whale. If it's standard CTS sizing, Shark-Bite will have fittings too.

Here you go...

Just be sure to order the correct size. Should be marked on the tubing and I'll bet it is 15mm. PEX fittings will work but you will only find them in English sizes not metric... same w/ Sharkbite. I doubt very much it is a flare ftg.

Best guess attached pic from the MS parts file

Order a couple spares as that one especially is prone to leaking - the nut that screws onto 1/2" MPT cracks from over tightening... replaced several myself.

[EDIT] SeaTech is now Agualock

This seems to come up a lot. Just to prevent confusion, PEX is a material, not a brand name. It comes in standard CTS sizes as well as metric (and probably a bunch of others). Shark-bite comes in standard CTS sizes. The Whale is metric. The Watts-Aqua Lock (formerly Sea Tech) comes in both. But all are suitable for PEX as well as other materials in the correct size.

Like the OP, my tubing is translucent PEX. Mine is 3/8 CTS. Key is to find your proper tubing size (mine is not printed on the tubing). Once you know your size you can find your options.

prospective, great explanation.

tubing on our pilot is smaller than 15mm. we have that on another boat. 3/8" sounds more like it. you jogged my memory, sea-tech was where i got extra fittings.

the fittings on our pilot had a collar and a threaded flare that was inserted into the tubing and then the collar was screwed down. they are definitely not the whale press on type fittings, at least not on our boat. going forward, i'll convert as needed.

I've spent enough time on this to make my eyes bleed. The name of that old style fitting with the collar and flare escapes me. It's exactly what I have on my boat. Mine are gray and come in multiple sizes. I did figure out what they were at some point and confirmed that they're not made any more. Once I determined my tubing size was 3/8, I've had success with Watts, John Guest, and Shark-bite. There are not as many types of fittings in 3/8 as 1/2. But there's a great selection if you go to the Watts-Aqua Lock web page. Pretty easy to search.

Sorry I wasn't clearer... what I really meant was you are not likely to find PEX tube or ftgs in metric sizes in any local / big box stores. I have always had to get them from a marine store of online.

I found the fitting on my 2005 Pilot II to be SeaTech, and I was able to buy fittings under that name two years ago. Good to know the name change to Aqualock. My PEX tubing is 15 mm.

My 1999 350 is 3/8" ID using the older style compression fittings. These seem impossible to find. They measure 1/2"OD, but it's not exact, so standard 1/2" push on fittings will not seal properly.

The size should be printed somewhere on the water line itself. It might be tricky to locate.

That's exactly what happened. The nut/cap broke where it attaches to the pressure regulator.
I traced the piping this morning. It's FLEXPEX 1/2 IN SDR9 PEX-a

The spec sheet for the regulator states the regulator has 1/2 " MPT (Male Pipe Thread) so maybe I have get a shark bite that will work. Luck my wife's had will fit in the hole!

Mine was the same style and is 3/8 ID as well. I've been able to find shark-bites in that size at lowes and home depot in limited styles, ie.. elbow, straight, tee. Watts/Aqua Lock has a huge assortment of 3/8 fittings including adapters and shut-offs as well.

I think Mainship must have made frequent production and supply changes. Mine is all 1/2 Pex. I don't have any red or blue pipe. I wish it did.

cartouche,

i don't think marlowe has anything to do with this. our 2003 pilot has the exact same semi-clear tubing. i think mainship was always looking for the lowest cost supplier and they shifted back and forth.
