Call Before Digging, Grading Or Leveling in Your Yard

!±8± Call Before Digging, Grading Or Leveling in Your Yard

Before digging in your yard, you will want to make sure that you know where all underground pipes or lines are. Your local power, cable, and water companies will come out to your home and mark the lines for free. This is a very important step in preparation before leveling your yard.

In your yard there are underground water lines, sewer lines, power lines, cable TV lines, gas lines, and possibly fiber optic lines. All of these pipes or lines cost a lot of money to fix or repair. You do not want to get stuck having to pay the cost simply because you did not do your due diligence before you started grading or leveling.

The reason companies offered to do this for free is so you don't have to have any of the lines repaired. It takes time and money to repair things. Make sure you call about a week ahead of time before you plan on leveling or grading your yard. Most of these lines or pipes are not very deep in the ground. Before you do any kind of digging or killing even for a garden, you should consult with your local power and water company.

You may also have a septic system or a will in your yard. You will need to get your surveyors map out to see where exactly the water line or the septic tank is. Septic tanks are generally not very deep in the ground. If you were to damage the top of the septic tank or crack it, you would have a big mess on your hands. Not only are they expensive to fix, but you do not want what is inside the septic tank to be in your yard.

It does not take long to do proper preparation before leveling or grading your yard. There are not many services that companies will do for free in today's world. The fact that power and water companies offer this service for free is a great benefit and advantage to you and me. Make sure that you take full advantage of this and prevent any damaging to lines or pipes that come to your home.

Commercial Or Business Fire Sprinkler Choices - Which Suppression System Will Work the Best?

!±8± Commercial Or Business Fire Sprinkler Choices - Which Suppression System Will Work the Best?

Commercial and residential fire sprinkler systems and other fire suppression systems have one goal: extinguish the fire in order to prevent and minimize property loss and lives. To this end, there are approximately 6 different types of fire sprinkler systems used throughout the U.S., wet pipe, dry pipe, deluge and pre-action, foam water, and "water spray systems". The two most commonly installed sprinkler systems in commercial environments and businesses are wet pipe systems and dry pipe systems.

Wet pipe sprinkler systems are the most popular type to have installed for a number of reasons. These systems are the simplest in function and therefore the most reliable. As expected, when the temperature of an area reaches a pre-set level, the glass bulb or link located at the affected sprinkler head releases allowing the flow of water. The cost of a wet pipe system is also usually the most inexpensive to have installed and maintain. Dry pipe systems are similar in operation with one key difference. Portion of lines leading to the fire sprinkler heads are filled with air. When the temperature at each individual head exceeds the pre-set limit, the individual sprinkler head is activated.

The air filling the line is expelled, then replaced with the water supply pushing in behind. The intended purpose of a dry pipe system is to allow for freezing temperatures and greatly lowering the risk of a freezing water line causing a rupture. A system such as this type can be less effective initially in extinguishing a fire due to the delay of water reaching the sprinkler head and dousing the fire. Increased cost of installation and maintenance, as well as complexity, can be a downside to installing this type of fire suppression system. Deluge systems and pre-action systems are similar to one another in that both are activated by some type of fire alarm system.

Deluge systems are common where the risk of fire spreading quickly is a concern. Deluge sprinkler systems, when activated simply spray water from every sprinkler head simultaneously instead of individual sprinkler head activation. Pre-action system can essentially be a combination of wet, dry and deluge systems. The advantage of a pre-action system is that it can send a trouble alarm should some problems occur without activating a sprinkler head. Some of this type of fire sprinkler system can also be set up for operation only when the temperature at a sprinkler head has exceeded the pre-set and a fire alarm is activated as well, essentially serving as a double check.

Foam water and "water spray" systems are usually installed where potentially hazardous materials are located and sensitive equipment. A mixture of foam and water helps to suppress the fire while the latter system sprays water in a particular spray pattern. These last two systems are not necessary for the majority of commercial businesses. Having any of these fire sprinkler setups is not enough.

Proper maintenance, as with any machinery, is necessary for successful operation. Depending upon the individual state or even local city laws, fire sprinkler systems are required to be inspected at least once per year, often more frequently. In order to receive discounts on insurance, insurance companies will sometimes require proof of inspection. Regardless of what type of fire sprinkler system being used, the cost of installation and maintaining the system will be miniscule compared to the loss of property, life and future revenue.
