The pump uses two leather cups back-to-back, attached to the plunger handle, to move material into the pump and out through the hose. When wet, these cups will seat in the barrel of the pump. When first using your pump, placing the leather cups in water for a few minutes will allow them to conform to the diameter of the pump barrel and work more effectively.

The check valves have white marks on the “top” side. For the system to work most effectively, these marks should be pointed upwards. The flappers in the pumps hang on hinges which work best when the hinges are at the apex of the flow.

Clamps are not necessary unless you plan to use the system in strong current and want to be extra cautious. For users in deeper water or stronger current, I have seen people wrap a leash around the lid and tie it off at their waist in order to prevent the bucket from breaking away.

Try to avoid moving overburden with the pump. Cut into the heavy sand with a shovel, then use the X-Stream hand pump to remove the target material from the bottom of the area. Don’t press down into heavy sand, but rather just hover the nozzle at the top layer so it can get sand and water, and the experience will be smoother. Keep the bucket as low as possible so you’re not pushing material uphill to get to the bucket.

The plastic valves can freeze and break if freezing occurs while they are still filled with water. Keep the pump inside warm and dry areas while not using.
