Re: Greenhouse problems/PVC

A minor but important part of my drip irrigation set-up in Florida was sked-40. It was exposed to all the elements for at least 10 years and no worse for it.

We used sched 40. It's great when it isn't exposed to strong sun. And
there
are a few pieces that are still hanging in after a few years, but most
got
brittle fairly quickly.

There are two types of white PVC.  There is the cheaper thinner one,

and
then Schedule 40 which is rated for outdoor use, and is much stronger, 
and

lasts
a long time.  We use the schedule 40 on our water garden

installations

and
other applications.

I've had  trouble with white PVC here in GA. It lasts for a year or

two,

then  fails, presumably because of the effects of strong sunlight.

And

the
gray PVC will sag when it gets hot, even though it doesn't get

brittle

like

the white stuff.
