Seems as though every season, I find a leak in the boat's pvc plumbing under the cockpit, under the gunnels and into the boat. Temperature swings, vibration and previous joint repairs are the most cause of my leaks.

This spring I'm gonna haul the boat for a couple weeks, remove the cockpit decking for some other maintenance... and run new lines with the more flexible Pex system. It'll connect to the exsisting pvc inside the boat. From the engine room forward, I have no plumbing issues but this will give me a chance to run and secure the new lines correctly where I wouldn't have the access with the deck on...

Anyone use this system before? They use it mostly in new home construction.

Hey Buddy, I've used it around the house ,when we remodeled the kitchen, 2 yrs and no leaks. Replaced some old gray quest on the boat with the white flex stuff the sale at HD last spring and so far so good.

Pex is commonly use is new boat construction it is easy to use and the fitting are a snap literally. I have used it to make repairs on my boat and I highly recommend it.

Used it for years on my F32 ... doesn't wear well and can crack under stress, but easy to use, and will hold well if protected (and drained prior t cold).

Ross you sure that wasn't the 1st gen stuff ? It did suck have it in my boat. The 2nd and 3rd gen stuff works well.

I've had both.

Both will freeze if you leave it full of water.

And both will crush if your don't protect it.

Overalll - its the best.

I don't care what you use if you live in an area that freezes then you need to winterize to avoid problems.

It's a good system. A good clean straight cut without any burrs, and proper support helps prevent leaks later. I highly recommend the use of the adapters they make to couple to other types of plumbing rather than rigging up something yourself or you'll be revisiting the issue.

Freeze, crush and hey I bet it'll melt to if you lay it on something hot. I'm missing you point on this one Ross.

Simply stating that it will crack if frozen.

If you leave it unprotected and it gets bumped (especially after several years of hardening), it will crack & leak.

Still easier/better than copper or PVC - just drain it, and protect it.

It seems that you are dealing with some problems in PEX pipes' temperature and pressure. You may check the seals for every connection and junction. Those parts of plumbing are prone for leaks.

and we use it all the time.It is great If used and installed correctly. Dont use the plastic fittings use brass if you can. For a total redo get the manibloc Its like a breaker box for water.
