Wow, we have a new twist on sprinkler repair. Broken sprinkler pipes occur for all kinds of reasons. Sprinkler Pipes break because: 1. They freeze (usually due to poor installation) 2. Cars or trucks drive up in yards and break them. 3. They blow apart under pressure (usually because primer was not used when the pipes were glued together).
This year we have had a lot of calls to fix leaking or broken sprinkler pipesdue to Earth Quake Damage. I would expect that in California, but Oklahoma? Since 1993 CMG has fixed sprinkler systems for all kinds of reasons. Earthquake damage is something new.
Over the years through trial and error, we have adopted many practices and procedures that insure the quality and longevity of the sprinkler systems that we install. These “extras” that are put into each Sprinkler System ensure that it will last and perform for years to come. Just a few examples are: Installing a master valve so the sprinkler pipes can drain underground automatically when the sprinklers aren’t running, Using “hot glue, ” not clear pvc cement so the sprinkler pipes won’t leak 5 years down the road, and finally using a ” compression T” to connect into your water line. This ensures that the connection wont break or leak.
My name is Blane Callen. I have owned and operated CMG Sprinklers and Drainssince 1993. I take great pride in my work. The Letters “CMG” stand for the first letter of the first name of each of my children. ( Chance, Melissa, Garrett ) = CMG
I have amassed a great deal of experience designing and installing Sprinkler Systems, Repairing Sprinkler Systems, and designing and installing Drainage Systems. In the past 19 years, I have made mistakes, but I have learned from them. As a result I get calls, from time to time, from other Sprinkler and Drainage companies that have run into a problem that they can’t handle. I am always glad to help.
I usually don’t take money up front for Sprinkler Installation, Sprinkler Repair, or Drain Installation. I prefer that the customer pay me when the job is complete and they are happy with the work. In a few cases on very large jobs I request a draw or outlay for parts. The parts are delivered from my supplier to the address where the job is being done and equal the amount of the draw. The parts stay on the premises until they are installed.

Just what is a “French Drain?” Many times people incorrectly
use the phrase, “French Drain,” to apply to many different types of Drains that could be used in a Drainage System. The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”
A Surface Drain has a grate that sits on top of a basin. The basin is underground. A Drain Pipe is connected underground to an outlet on the Drain Basin. Storm-Water Drains through the grate into the Drain Basin. Once in the Drain Basin, water travels out of the basin through a Drain Pipe. The Storm-Water continues downhill in an underground Drain Pipe to an exit point.
THIS IS NOT A FRENCH DRAIN!
- Surface Drain and Drain Pipe
A French Drain is completely different from a Surface Drain. A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench. The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe. This is to ensure that the Drain Pipe does not become clogged.
The dirt that was taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drainabout 20% of the time. Most of the time a liner in not needed.
