Dry riser testing in Hertfordshire follows BS 9990 like anywhere else in England: a visual inspection every six months and a pressure test once a year, with the riser held at 12 bar for 15 minutes. St Albans and Watford are our regular Hertfordshire stops, 47 and 53 miles from our base on the M1, and dry riser testing elsewhere in the county usually fits the same runs. Sentry Sprinkler Protection does this work across England from its base in Kettering, ISO 9001 certified.

What a test visit covers

  • Every six months: the inlet cabinet, the inlets and caps, each landing valve, the air release valve, the drain and the signage, floor by floor.
  • Once a year: the riser filled and held at 12 bar for 15 minutes, with the landing valves worked under pressure.
  • Seized valves, missing caps and damaged cabinets photographed and listed, each with its own price.
  • A certificate for the building file, naming the riser, the floors and the result.

On the same run as St Albans and Watford

Our Hertfordshire work is planned in runs along the M1, so a building in the county is usually tested alongside visits already booked in St Albans or Watford rather than needing a day of its own. That is also how six-monthly dates stay fixed: the run repeats, and your riser is on it.

Tell us where the building is before anything is booked. If it does not fit a run, we say so plainly rather than promising a date we would struggle to keep.

Flats, offices and conversions

Much of the county's riser stock sits in blocks of flats, office buildings and offices converted into flats. A conversion is worth a closer look: the riser may predate the change of use, and the record often stops at the old layout. We test what is actually installed and note where it no longer matches the drawing.

Where a building also has a BS 9251 sprinkler system or a wet riser, each is tested to its own interval on one schedule, so the managing agent has one date and one record per block.

When a riser fails

A failed test is not left as a line on a report. Each defect is priced separately, repaired on a return visit, and the riser is tested again, so the certificate describes the riser as it actually is.

Switching from another contractor?

It happens often, and mid-year too. You do not have to wait for the old contract to run out to find out where your dry riser stands.

  1. Send what you have

    The last service report, the certificate, or a photo of the valve set. Whatever you have is enough to start.

  2. We survey before we quote

    What is installed, the standard it was designed to, whether the pumps make their duty and what the last reports found. Free, and written down.

  3. A clean record from our first visit

    If the old records are thin we say so and start a clean record, rather than sign off work we did not see.

When is your next visit due?

Pick the system and the month a contractor last came. You will see each routine, the date it falls due and anything that is already late.

Weekly checks are your own team's, logged on site. Our free weekly test log covers them on one page.

Counted from the visit you picked. If that was not the annual service, the annual may fall sooner. Your insurer or fire strategy can ask for more.

  • Lewis W. Sprinkler installation, warehouse

    Had them install a full sprinkler system across one of our warehouses, and couldn't be happier. They were professional from start to finish and the on-site team were genuinely friendly to work with. […] Highly recommend if you would need your building or warehouse properly fire-protected.

  • Mike C. Weekly maintenance, testing and repair

    Sentry Sprinkler Protection have recently taken over the weekly maintenance, testing and repair of the […] sprinkler equipment. They are providing a excellent service, good value and they are also very helpful when on site.

  • Sam E. Sprinkler pipework installation

    Couldn't recommend [Sentry] enough. Their work ethic, consistent efficient install of the pipework and overall approach to a project should be something every sub-contractor strives to mirror. Marius is incredibly approachable and methodical in his work with laydown areas kept very neat and tidy and all work carried out in a safe manner.

Questions about dry riser testing in Hertfordshire

Which parts of Hertfordshire do you test dry risers in?

St Albans and Watford are regular stops, and the rest of the county usually fits the same runs along the M1. Send the address and we will tell you straight away whether it is a normal visit or a planned one.

How long does an annual dry riser test take in a Hertfordshire block?

Usually part of a day for a single riser. The riser is filled, held at 12 bar for 15 minutes and drained, and every landing valve is checked. Access to each floor is the part that sets the timetable, so it is agreed before the day.

Can you take over dry riser testing from our current contractor?

Yes. Send the last certificate if you have it. We test the riser as it stands, note anything the previous record missed, and put it on a fixed six-monthly date from then on.

What happens when you ring

You talk to Marius Bucur, who runs the company and prices the work. Not a call centre.

07927 555475

Mon to Fri, 7am to 5pm. Emergencies any hour.

Rather type?
  1. A few plain questions

    Usually four: what the building is, what system it has, when it was last serviced and the postcode. If you do not know some of it, that is normal.

  2. A straight answer

    Whether it is a job for us. If a building would be better served by someone closer, we will tell you that too.

  3. A free survey, on your dates

    Then a fixed price in writing, line by line. No survey fee, no obligation, nothing added afterwards.
