ThisÂ "shallow-suction device", can be mounted on both the DOC3 and DOC7 models. It ensures complete drainage of flooded floors (to 3mm from floor).
Please note that automatic pumps will not pump down to the level of the device. The pump will require manual operation or another form of control to pump down this low.
This "shallow-suction device", can be mounted on both the DOC3 and DOC7 models. You need to start with enough water to prime the pump (aproximately the pump ring) but then it can drain down to only 3mm of water!
If you have a manual Doc One or Doc 7 then we highly recommend this great accessory.
