Fire Sprinkler Systems

Fire pumps are used to aid water supply where there is little or no water by helping to boost water pressure. Fire pumps are also vulnerable to external factors such as corrosive environments, tampering, accidental damage and careless use. Because they are used infrequently, fire pumps must also be routinely inspected to determine their condition, operability and need for routine maintenance. Weekly testing is a good idea, but pumps must be tested at least once a month. Annual testing is conducted at minimum, rated, and peak load to ensure that the fire pumps will work optimally under all of these conditions. Every three years, demand must be placed on the suction supply to test the hose streams and flow meter systems. Trust LVC’s experts to perform these complex and necessary inspections.

Wet pipe systems are the most common fire sprinkler system. They offer a simple system that is highly reliable. Generally, they are economical to install, modify and maintain. A wet pipe system is one in which water is constant­ly maintained within the sprinkler piping. When a sprinkler activates, water is immediately discharged onto the fire.

A dry pipe sprinkler system has pipes that are filled with pressurized air or nitrogen, rather than water. Dry pipe sprinkler sys­tems provide automatic protection in spaces where freezing is possible. Typical dry pipe installations include unheated warehouses and attics, outside exposed loading docks and commercial freezers.

Pre-action fire sprin­kler systems use automatic sprinklers attached to a piping system containing air – which may or may not be under pressure. The basic concept of a dry pipe system is that water is not normally contained in the pipes. The difference, however, is that water is withheld from piping by an electrically operated valve, known as a pre-action valve. Valve operation is controlled by independent flame, heat, or smoke detection.

A deluge fire sprinkler system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pres­surized with air. Deluge systems differ from conven­tional sprinklers and are generally used for industrial type hazards that require the application of water over a large area.

Since 5-year fire sprinkler inspections happen infrequently, it’s easy to forget about them. With all of the other expenses that come up on a regular basis, a not-so-regular inspection can fall through the cracks. The simple fact is that every commercial building with a fire sprinkler system is required by NFPA 25 to carry out a 5-year inspection.

Every five years an inspection must be performed while the sprinkler system is shut down for the purpose of internal valve investigation.  At the same time, your pipes are investigated for any kind of internal or external obstruction.  If certain conditions exist, a more comprehensive inspection might be needed.  Trust LVC’s experts to help you navigate NFPA code to determine which kind of obstruction investigation is needed for your facility. 

Whether we find needed repairs as part of our inspection process, or you find something and it’s an emergency, call LVC for 24-hour service. Trust our experts to help quickly find problems with your sprinkler system and repair the problem and its source with limited downtime or business interruption. We also help to maintain your systems, helping you avoid emergency situations.

LVC installs tenant improvement sprinklers in every type of building and occupancy – from executive offices and prison cells to government approved clean rooms. We design and install pre-action fire sprinkler systems designed to address the specific needs of a space being remodeled.

Upon completion of inspections, LVC provides a detailed inspection report which summarizes our findings, including detailed documentation of any deficient findings with recommended solutions and repairs. As repairs are completed, we provide additional documentation of corrective actions to keep your system documentation current.

Regularly scheduled fire sprinkler system inspections provide opportunities to consider updates, provide greater long term protection and ultimately, save you money. LVC’s inspection programs meet national fire codes, manufacturers’ requirements and your needs. We inspect new and existing systems ensuring fire code and insurance compliance. LVC performs inspections on all kinds of systems include wet, dry, pre-action and deluge.

Trust LVC to do your required monthly, quarterly and annual inspections.  Using electronic documentation, we provide you with detailed information on the areas of your system tested and related results.  Electronic documentation not only helps you stay organized, it keeps information in an easy to store, easy to search and easy to find format.  We can also provide you with training in the proper use and maintenance of your system. Inspections are performed by LVC technicians—with no sub-contracting; this gives us better control over the quality of service we are able to provide.

Since fire pumps are infrequently used and deteriorate over time, it is important to have them inspected regularly to determine their condition, operability and need for routine maintenance. Annual testing should be conducted for rating and peak load to ensure that your fire pumps will work optimally as needed.
