Our customer, Sennen Property Management, needed to perform an annual static pressure test of Dry Risers for a new block of flats in London. British Standard 9990 requires dry riser systems undergo an annual static pressure test and inspection and a six monthly visual inspection by a competent company.

RES has a dedicated Fire Hydrant and Dry Riser test team and equipment for its inspections. In order to carry out a Dry Riser test, a large bowser is needed along with a water pump to simulate a fire engines pump being connected to the dry riser column.

A dry riser is basically an empty pipe that runs up a building which can be externally connected to a pressurized water source by fire fighters. This vertical pipe can then distribute water to multiple levels of a building when fire fighting hoses are connected to an outlet valve typically located on each level.

A Dry Riser test involves sending pressurised water up the column to ensure that the pressure is maintained, that there are no leaks or faults and that the air release valve (located at the top of the column) is working correctly. The column needs to be able to maintain 8 – 10 bar of pressure for 15 minutes. The water that is sent into the column comes back out of a drain valve and back into the bowser, ensuring that water can be re-used for another test.

“At Sennen Property Management the safety of all our sites and the residents is paramount which is why we use RES as it gives us the peace of mind that all our fire safety systems are maintained to the highest standards.

High quality contractors are key to our business, and with RES we know we use the best in the industry to keep our sites compliant and safe for all our customer”

Tony Collings, Director, Sennen Property Management Ltd

Our customer was transitioning from temporary buildings to new school buildings and asked RES to provide extinguisher sales, installation, servicing and additional fire safety equipment for both the new and old sites.

RES provided a comprehensive proposal to cover all the necessary fire extinguisher equipment for the new school buildings.

RES also provided an audit of existing fire extinguishers from the temporary buildings so that they could be re-instated on the new site.

The Wren School is now a modern Secondary education establishment catering for over 1000 students.
It comprises of a sports hall and two L shaped buildings containing classrooms, laboratories, offices, restaurant/cafe and a theatre.

In total, over 50 new extinguishers were commissioned around the site as well as fire action signs, extinguisher stands, fire blankets and fire evacuation chairs on the stairwells.

RES has provided a competitive, comprehensive and compliant extinguisher equipment service for this new school and will continue to ensure total fire protection is provided by carrying out annual fire extinguisher servicing.

“RES helped us to stay safe whilst the development was underway and then continued to provide excellent service in our new home”

Cary Stubbs, Senior Caretaker, The Wren School

RES provides schools and businesses with a range of fire protection services including fire alarm servicing, servicing of fire extinguishers, fire safety signage services, fire safety training and fire hydrant testing.

As part of our schedule of works, we carry out the periodic inspection of the Fire Hydrants (which must be done every 6 months) in accordance with BS 9990 : 2015 Non-automatic fire-fighting systems in buldings Code of Practice.

By using the “TSI Digital Flowmaster 250”, the latest digital flow testing equipment available, our engineers are able to digitally record a fire hydrants water pressure and the flow rate reading to a 98% accuracy.

The latest equipment we use enables our engineers to provide an efficient and more reliable test environment than that of a traditional hydrant test equipment.

Our investment in this technology is part of our ongoing commitment to customer service and maintaining a high quality of work.
