The Sentry™ Sump System
 The Sentry Sump System has been designed to complement the Oldroyd Xv Clear studded membrane system and the Aquadrain perimeter drainage system when they are used to waterproof basements and underground structures. It was developed by Safeguard in conjunction with pumping solutions specialists, Edincare.
When it is known or anticipated that free water will be present behind the Oldroyd Xv membrane, the installation design should incorporate adequate provision for its disposal. This will normally require the installation of one or more sump pumps.
The Sentry Sump System comprises of three standard models, each contained within a tough, purpose designed 100-litre capacity sump chamber. The choice of model will be based on two major considerations:
- Anticipated water ingress
- Potential consequences of the basement flooding (risk vs cost)
The Sentry Sump Range
 |
Sentry Single - Entry level system with single Ama-Draimer 303 sump pump and dual power alarm.
|
 |
Sentry Twin - Includes two Ama-Drainer 303 pumps and a dual power alarm. Designed for use in situations where a higher level of water ingress is anticipated or where additional backup is required. Dual outlet pipes allow both pumps to operate at full capacity. |
 |
Sentry BB - Provides the same benefits and efficiency as the Sentry Single system but with the added reassurance of a battery backup pump that is able to operate for a period of time in the event of a failure such as a power cut. |
Where particularly high levels of water ingress are anticipated, several sumps and pumps may be required. Your basement waterproofing contractor will be able to suggest the most appropriate solution for your basement.

 All models in the Sentry range feature dual-power alarms (pictured) as standard. These alarms run on mains power, but switch to battery power in the event of a power-cut or other mains failure. The battery is trickle-charged and will last for several years before it needs replacing. On the Sentry BB system the alarm is incorporated into the battery backup control panel.
High-Capacity Pumps
 All Sentry Sump Systems utilise the same Ama-Drainer 303 high-capacity pumps. These can provide high pumping capacity even where water needs to be discharged several metres above pump level (a common requirement in basement situations).
The pumps are built to high engineering standards and feature built-in non-return valves.
Maintenance
Pumps are mechanical items and, as such, require regular servicing if they are to continue to perform to their optimum capabilities. Professional basement waterproofing companies offer pump service contracts and are able to advise on an appropriate service interval.
