Avoid too common
pitfalls...
We encounter a lot of unusual
"custom installations" while doing repairs.
Some are done by well
intentioned homeowners, some by their gardeners or others whom the
contractors license
board calls
"unlicensed operators". We are often
called out after someone else gets it wrong.
Some are simple correctable
mistakes; others are serious code violations. Most are attempts
to get a job done quickly or cheaply by cutting corners.
According to Rain
Bird's website....
"You Get What You Pay For"
"When choosing a contractor, you should
be wary of those who offer to charge you significantly less than
other contractors. Low bidders may not be licensed or insured and
often use cost-cutting techniques that can jeopardize your lawn
and shorten the life of your system.
Watch out for these commonly
used tricks of the trade:
-
Not
including a backflow preventer, which is
required by local codes to protect your drinking water
supply.
- Installing sprinklers too far
apart, which makes it impossible for certain
areas to receive enough water and causes brown spots during the
hot summer months.
- Mixing
sprinklers with different application rates on
the same line, which causes one area to be overwatered in order
to sufficiently water another.
- Not
using special watertight connectors and a
protective valve box to safeguard the electrical elements, guard
against short circuits and prevent
corrosion."
Here are a
few common "corner-cutting"
mistakes we've encountered when we're
called out to fix a job that someone else
installed:
-
Forgetting to install filters in
spray heads.
- Bad glue
connections and fittings that aren't fully
inserted.
- Using
thin wall pipe, either Class 200 or Class 125.
We find that neither really holds up as well as Schedule 40 PVC
in the sizes (3/4" through 2") that we normally use in
residential irrigation.
- Forgetting to install shut-off
valves to isolate the sprinklers from the house
water supply so that a repair requires turning
off water to the house
- Not
regulating water pressure. Water pressure in some local foothill areas can be
as high as 160 PSI. Spray heads operate best at less than 50
PSI. An adjustable regulator on your mainline solves the
problem.
- Using
too many heads on a line often exceeds
manufacturer's specifications for water velocity, resulting in
"water hammer" which can damage your pipe and crack or loosen
fittings in sever cases.
- Connecting copper to galvanized (iron)
pipe. Not only is this a code violation, but it
shortens the life of your plumbing. The reaction between
the two metals causes each to corrode faster. We've
seen galvanized fittings threaded to copper that fill up more
than half way with rust, severely restricting water flow. The
common scenario: someone doesn't have a brass fitting on the
truck, and instead of running to the hardware store he uses a
galvanized tee instead, costing the homeowner
later.
Irrigation Hall of Shame
nominees:
Internal corrosion of galvanized pipe
that was connected to copper.

Anti-siphon valves installed below grade (a
code violation).
And, it might even work, but ask
yourself...
