David,
the pex installation with the simple pex insert fittings and band clamps
are no more expensive that any other hosed connection. It can be more
expensive if you make it that way by using shark bite fittings and
such. The banded clamps are really cheap and it you're not adding
valves or distribution blocks it is just as inexpensive, maybe even
more-so, than reinforced hose with quality hose clamps. I made home
runs of everything because I'm just out of my mind... You can just run
mains and tee off, locally, to various fixtures just as they did in the
factory. the pex system would be faster too, because you would not
need to be tightening up all those hose clamps, the pex bands are also
way less bulky.
you can see for yourself on Sunday.

Josh, Bob (and others),
Thank you. I was thinking simple plastic barbed fittings with
reinforced hose and hose clamps are simple and effective. My only
concern, from reading, is the hose not being opaque enough to
eliminate any growth in the lines. But then, these water hoses are
all hidden and out of the sun so no issue there (I believe).
The PEX and Sharkbite systems all seem to be an expensive,
over-engineered solution for this simple application. Which is why I
asked the question to begin with.
Thanks again.

Shark bite is one popular manufacturer. They are typically metal
fittings and considerably higher cost compared to the plastic
alternative made by Watts. Both are significantly more expensive than
the barbed fittings and crimp.
In residential settings one of the significant cost advantages is the
"home run" topology. Since the tubing is flexible, elbows and tees
are no longer needed like they would be on a copper installation.
Similarly the time associated with assembly is reduced considerably.
One continuous pipe from source to destination. The bend radius and
methods of securing the tube/pipe in place makes the "home run" a bit
more challenging on board a boat.
A home run using a flexible drinking water hose product like that made
by Shields or Trident is my choice. The flexibility coupled with the
freeze protection and durability all and up to a quality and lasting
solution. Use barbed brass fittings and clamps. It sounds like this
was Bob Boyer's solution.

This is the lowest price per foot I could quickly find... And it is
more expensive than PEX.

I’ve done a couple of plumbing and landscaping projects using PEX
tubing. Lowes and probably Home Depot sell a fitting for PEX
tubing that uses small teeth where the fitting engages the tubing
and requires no special tool. You simply push the fitting into the
tube. I’ve not had any leaks I know of. I can’t recall the brand
name.

I am sure this has been gone over before...so please indulge me.
Replacing, re-designing, water lines in 1981 40-2. Pex is the
obvious choice. Are there less obvious (and have cheaper tools
required to install) choices?
Has anyone improved on the original design? I am thinking of
adding easier accessible manifolds and an additional line for
antifreeze and blowing out water.
Thanks in advance.
