Care & maintenance
Looking after your Boost pump
A modern pressure pump doesn’t ask for much, but the few things it does ask for make the difference between one that runs quietly for a decade and one that fails early. None of this takes long.
The golden rule: never run it dry
Running a pump without water is the single biggest cause of early failure, it overheats the seal in seconds. Always make sure the pump and its suction line are full of water (primed) before starting, keep your tank from running empty, and don’t leave it switched on drawing from a dry source.
Keep it dry, ventilated and frost-free
House the pump somewhere waterproof, well-ventilated and out of frost. Water sitting around the motor or in the electrical connections is a problem; so is a pump baking with no airflow, or freezing solid in winter. A simple cover or housing that still lets air move is ideal, and keep insects and debris out of any vents.
Catch the small things early
- A new grinding or rumbling noise (usually bearings).
- A drip from underneath the pump (usually the seal).
- The pump cycling on and off more than it used to (a leak or a tired pressure tank).
- A change in pressure. Each of these has its own guide, and catching it early is far cheaper than a failure.
A quick seasonal check
- Look for weeping fittings and tighten anything that has worked loose.
- Clear leaves and debris from around the unit.
- Check the pump is still bolted down firmly on its base.
- If you have a pressure tank, check it still has its air charge.
When to have it serviced
Wear parts like the seal and bearings have a life. If the pump is noisy, weeping, or not holding pressure and the basics check out, it’s due for a service by a pump technician. On a smart pump the app history is genuinely useful here, it can show a technician exactly how the pump has been behaving.
Safety: Always switch off and unplug the pump at the power point before cleaning around it or touching a fitting. Any electrical work must be done by a licensed electrician.
The app does the watching for you
The nice thing about a Grewa pump is you don’t have to remember to check it. It watches its own pressure, power and running pattern, flags a fault the moment it appears, and even picks up the quiet signs of a slow leak. Most of the maintenance above is just calmly responding to what the app tells you, before it becomes a problem.
Common questions
How often does a pressure pump need servicing?
With good conditions and no dry running, a quality pump can go years without a service. Have it looked at when it starts telling you something is off, noise, a weep, or not holding pressure, rather than on a fixed schedule.
Do I need to do anything in winter?
Keep it from freezing. Water expanding as it freezes can crack a pump or its fittings. If it’s somewhere exposed, insulate or house it before the first hard frost.
