Our sprinkler tank repair system involves the physical repair of existing tank perforations, followed by a corrosion resistant coating to prevent any further corrosion or leakage. The following procedure is the most frequently used repair system, however other systems are available to suit each individual requirement.
The sprinkler tanks inlet valve is closed and tagged, followed by the isolation and electrical tagging of all pumps and power supplies. The sprinkler tank is then drained over a 24-hour to 36-hour period, depending on the size of the vessel. This avoids any drains backing up and flooding the tank area.
On completion of the draining, confined space and ventilation equipment are positioned at the sprinkler tanks access point, and any permits or method statements are checked and signed. Any remaining water, sediment or silt is removed using submersible pumps and wet vacuums. A mobile scaffold is then erected within the tank to allow surface preparation to commence. The tanks internal surface is prepared using blade scrapers and brushing followed by 3600psi jetting.
