Needs a better pump

This is a decent enough set but I find the pump is not sufficient for a decent current or return flow. Unless your pond doesn't have any depth it struggles with the vertical aspect from pump location to return. Went with this as the specs were far more than needed for my small pond but if buying again would go for a bigger one. By the time I had realised it was too late otherwise I'd have returned it

Great little kit

I only have a small pond so I didn't want anything too big and bulky spoiling the garden. I spoke with one of the guys on the phone and they pointed me in the direct of this kit. I have to say it's wonderful.

Questions and Answers (1)
Glenn Watson Asked:

Does the Oase Biopress 4000 set have sufficient pressure for a fountain or spout to return the water to the pond?

We Replied:

Dear Glenn Thank you for your question. The pump in this kit will not be able to run a fountain as it draws in larger debris and this will block a fountain head. It will be able to supply enough to return the water to the pond via a small water fall or spouting from the end of hose. Should you wish to contact us further or to place an order, please call us on 0121 355 7701. Thank you for using our online Q&A system. Kind regards Paul Ilsley
