WaterMate Mini pump : installation – Harvst

The WaterMate “Mini” version is supplied with a submersible pump which is placed into your water tank or water butt.

It’s designed to remain underwater throughout the season (but remove in winter)

The mini pump comes fitted with a 1.5m cable, designed for water tanks kept within the greenhouse.

Pump extension cables are available for tanks outside the greenhouse. Note that the mini pump doesn't have the same pressure capabilities as the pro pump, so you should keep the water tank as close as possible to the watered zones.

Installation process

Place a larger jubilee clip over the garden hose and then attach the hose to the barb on the pump.
Tighten the jubilee clip once the hose has been fully pushed onto the mini pump barb end.
Drop the pump into your water tank.
Route the hose from your pump to the inline water filter. Cut the hose in a suitable place to fit the inline water filter.
Place the larger jubilee clips over the hose and then secure the hose ends to the filter ensuring the correct orientation of the filter. There are arrows on the filter to show the flow of water.
Route the hose from the filter to the input side of the water valves.
Cut the hose to the correct length.
Fit a snap-on female garden hose attachment.
Connect to the water valves.

Maximum capacity

Maximum capacity is a guideline only, and can be affected by the length of inlet hose, the height that the pump has to bring water up from a tank, the state of filters, and the battery level (for solar units).

We recommend no more than 4m of inlet hose between the pump and the water valves. Ensure you have no kinks in the hose (also consider that on a hot day the hose will get soft, and any weight on a bent hose may cause a blockage).

The pump will supply enough flow rate and pressure for up to 6 sprayers per zone (12 in total, i.e. 12m2 coverage).

Alternatively, up to 40 drippers (20 per zone).
