Any plumbers who know the IRC here?

On my final inspection today I got gigged for not having shut off valves at
each fixture (bath vanity sink and toilet).

This is plumbed with PEX, with a MANIBLOK.

"Fixtures shall be connected to drain and water lines. Shut off valves shall
be installed for all plumbing fixtures [IRC P2903 & P2903.8.6]
Comments: Need shut offs at each fixture."

That's what a maniblok does--provides a shut off for each supply line.

In my home county only the maniblok shut offs are required. The plumbing
supply house doesn't even have 3/8" x 3/8" PEX shut off valves. But in the
county where I am building, I failed.

Someone is right per IRC and someone is wrong. What do you think?

What comes to mind is that if your kids are at home alone and the kitchen
tap gives out and starts spraying water all over the place, the most obvious
place for a shut off is, well, under the sink. Codes like this are usually
designed so that even the most ignorant person could, in a pinch, have a
hope in hell of turning off the water, gas, electricity and so forth in case
of an emergency. Considering the cost of a plain-jane shut off valve, and
in particular the ease with PEX installations, I don't see why you wouldn't
put a shut off at each fixture.

Not to mention, it's just plain good sense to have the valve right under the
fixture.

IMO you are probably correct per the IRC...........

Yes, a PEX system with a valved manifold satisfies the requirement for
a fixture shutoff.

But is "situation" would you rather reach under the sink & flip a 1/4
turn angle stop or run to the manifold (if you know where it is) ?

Once at the manifold which valve to do you flip? Or (if installed)
just cut off all water (hot & cold) to the manifolds?

I've done a couple PEX systems & I love the valved manifold (kinda
spendy, though)

yeah, I toyed with the idea of no angle stops on my first
installation......cleaner, easier, cheaper installation

but I still chose to install angle stops......just made better sense.

While you might regret NOT having an angle stop, you'll never regret
having one. :)



cheers

When one of the someones is the inspector, he is by definition always
right! <g>

As others mention valves at the fixture are a really good idea.
