Three years ago I ran some plastic tubing (which I believe was
polypropylene) from my water softener in the garage, through the brick
exterior wall and into my subsurface drainage system. The tubing
cracked at the outside of the wall and before I replace it, I'd like
some advice if polypropylene is the best material to use for this
I would be more inclined to "Tygon," which is the clear flexible
stuff. Use some silicon caulk for a seal where you go through the
wall. It has a LOT more "give" to it. My local Ace hardware carries it
in all sorts of diameters with "jag" fittings, etc.
Thanks for the tip. I need to make a tight turn to keep the tubing
out of the way. I wonder if Tygon's flexibility will make it likely
to close off like a bent water hose.
Also, whatever tubing material I use, can't I completely eliminate UV
degradation by wrapping the exposed section with electrical tape, duct
tape, or both?
Just the other day I saw these spring like things to put on "universal"
automotive coolant hoses to make them bend where you want and to keep
them from collapsing. Personally I'd probably just use some PVC.
I'm curious about your drainage system. My softener was regurgitating
down into a hollow, (a hollar here), and it killed 3 large oak trees.
The salt got to the largest roots and even though they appeared healthy,
strong winds knocked them down one by one. The largest roots where dead
and black, others looked fine
For the last few years I've been letting it drain into the gravel in the
pump house which is surrounded by a paved drive and the slab the house
it on. No problems yet but I'd hate for it to reach a giant oak in
front of the house.
Thinking of watering it down by draining it into the septic, but one of
the leach fields goes close to the large oak I'm worried about.
Yes, the salt water discharge from a water softener is definitely
harmful to plants. I only discovered that my line broke after it
killed off half of my wife's flower bed.
Before I bought the house, the previous owner installed a drainage
system because the back yard tends to flood. It all works by
gravity. There are five cement wells, perhaps a cubic foot each,
connected by 4" thin-wall PVC. Water flows into the wells through a
screened grate, through the pipe, and out into the street where it
goes down the storm sewer. Although it wasn't my design, if you have
any more questions I'll do my best to answer them.
Also, if I were inclined to re-install the discharge line, I'd
definitely use PVC this time rather than flexible tubing.
