Sprinkler System Checkup Norman.

Lots of things can be done to make sure your Sprinkler System is ready to go.  All the Sprinkler Zones should be checked one by one.  The sprinkler heads and valves need to be checked to see if anything needs to be adjusted or replaced.

Sprinkler System Checkup is a Service Provided by Oklahoma Drainage since 1993.

Today we did a sprinkler repair in Norman.  The sprinkler system needed a checkup.

We went through each sprinkler zone and identified several different problems.

Zone 2 had a cracked sprinkler pipe in a flower bed.

A broken Rotor Sprinkler head was found immediately.

Next, zone five look good with no problems.

Zone 6 and 7 each had a couple of pop-up spray heads that were worn out and would not pop-up.  The diagnosis and the repair took less than two hours.  Now their sprinkler system is running great!

What is a Back-Flow-Valve?

A Back-Flow-Valve is a part of a Lawn Sprinkler System.  Water passes through it from the water source which can be a Water Meter or a Well Pump.  It forces water to travel in only one direction from the source to the sprinkler system.  It can’t travel backward back to the water source which again is a water meter or well pump.

A Back-Flow-Valve provides protection to the water source from back pressure and chemical contamination from lawn fertilizer.

Most Cities require a Back-Flow-Valve as “Code” for Sprinkler Installation.

Emergency Shut off

Back-Flow-Valves usually have an Emergency Shutoff valve on them that can shut off the water to the lawn sprinkler system but keep the water turned on to the home. Most Back-Flow-Valves have two Emergency Shut off Handles.  Either one will work.  Many times, they are hard to turn, however.

If there is a leak or water is shooting up in the air just turn the valve handle and give us a call.

Norman Sprinkler Checkup is a Central Focus for Oklahoma Drainage.  We Performed or first Sprinkler Repair in Norman in 1993.  It was in Brookhaven on the West side of Norman.

Recently we had a customer in Oklahoma City who wanted to move his Sprinkler Valves.  They were in a bad place in his flower bed.  He wanted to plant a tree where the valves were located.

We moved 4 Sprinkler Valves about feet out into the yard.  All the Sprinkler Pipes had to be redesigned and installed matching the new location and maintaining full functionality.

 

Now is a good time to have a Sprinkler System Checkup provided by Oklahoma Drainage.

Sprinkler Systems need to be checked before winter to prevent pipes from freezing.  Sprinkler Design determines whether sprinkler lines need to be bled.  Emergency shut off valves also need to be checked and turned off for the winter.

In the Spring, all the water needs to be turned back on and all sprinkler zones and heads need to be tested.

First Step

First, we dug up a good working area surrounding the broken Sprinkler Valves.  Next, we cut out the broken valves and crushed PVC pipes.  Finally, PVC pipe was cut and glued with new Sprinkler Valves following the original design and configuration.  In this case the three original sprinkler valves were connected to each other inside one Valve Box.

We aren’t done yet though; two sprinkler wires must be connected to each Valve.  One sprinkler wire is the “Common Ground.”  The other wire is the power wire.  All the sprinkler wiring is connected with water-proof wire connections.

The Common Ground wire and the Individual Power Wires all come from the Sprinkler Controller.  Each Sprinkler Valve has its own power wire coming from the Controller.  All the Sprinkler Valves are Connected to the Same Common Ground Wire.

Before We Finish

Before dirt can be put back around the new valves, testing must be done.  Each valve must be turned on, “one-at-a-time,” at the Controller to ensure good wire connection and functionality.  Also, the Sprinkler Valves must be checked for leaks in the PVC Pipe.

Sprinkler Controller Repair is a service provided by Oklahoma Drainage.  A Sprinkler Controller is the “Brain,” of a Sprinkler System.  They can wear out or stop working.  Power surges in the home can cause damage to a controller.

Programming can be difficult for homeowners.  We can help with programming or replace a Sprinkler Module if it is defective.

Start Time Programming

“Start Time” programing many times is confusing for homeowners.  The definition of a Start Time is a time that is chosen for the sprinkler system to start watering.  It causes zone 1 to start running.  When zone 1 is finished it automatically stops and zone 2 begins.  When Zone 2 is complete it stops and zone 3 begins.  Simple enough Right!  This continues until the last zone programed available runs.

The confusion begins when people think that a time needs to be set to start zone 2 and 3 and so on.  This is not the case.  They follow zone 1 which has the only Start Time programmed into the controller.

Be Careful with Multiple Start Times, just use One at first.

Sprinkler Controllers have a feature providing multiple start times, up to 4 Start Times are usually available.  These additional start times are only used when a person wants to run the entire system more than once in a 24-hour period.

For Example, the first Start Time is set at 9Am.  Zone 1 begins to run at 9am.  When Zone 1 is done, say 10 minutes later, Zone 2 begins and runs for 10 minutes, then zone 3 follows and so on.  By 10 am let’s say all the zones have run.  Let’s say 8 hours later you have a second start time at 6 Pm.  Zone 1 comes on and runs and by 7pm all the zones have run again.  So, the controller has 2 start times which have caused the Sprinkler System to run start to finish twice in a 24-hour period.

Here is the big problem!  Some Homeowners believe the second start time is to start zone 2 running.  They also think that the 3rd start time is to start zone 3 and the 4-start time is to run zone 4.  No!!

So, this is how they program the controller.  At 9am they have a start time and zone 1 starts.  The homeowner programs a second start time at 9:10 am to mistakenly start zone 2.  Nope!  It starts zone 1 all over again.  At 9:2o they have a 3rd start time for zone 3.  Nope!  It starts zone 1 for a third time.  Now the controller is stuck in a loop and zone 1 runs constantly and won’t shut off.

If Sprinkler Controller Programming is confusing?  Make sure you only have One Start Time!

“Run Time,” is completed Next.  It determines how long each zone runs.  Zone One 10 Minutes,     Zone Two, 15 Minutes, Zone Three 8 Minutes.  You can set how long you want each zone to run.
