4 to 5 PSI is usually enough. In windy weather, raise it to around 7 PSI. In hot weather, keep it at the lower end, because the air expands as it warms up.
Recommended pressure
Normal conditions: 4 to 5 PSI.
Windy: up to about 7 PSI.
Hot weather: stay at the lower end of the range.
Which pump?
We supply a manual pump.
You can use a high-volume, low-pressure electric pump, such as a tent or paddleboard pump. You may need extra valve fittings.
Don't use a high-pressure, low-volume pump such as a car tyre pump.
Three valves give you a choice of inflation point, which helps if your electric pump has a short lead.
