    Hi all,

    I have seen some discussion around how one could utilise a ram pump within their AP system.

    I was thinking for me, I am on a very steep slope so the gravity flow from the tanks into the sump could go into the ramp pump and then push back up the hill abou 20% of the inlet water, whilst still having the normal pump running.

    So in the event of a power failure, I was thinking the ram pump would keep working for a period of time as it would be pumping up the hill some of the water that was within the system, how long I do not know. BUt if I also add a small battery backup pump that pumps water only a short distance up the hill, into a pre sump, and use that flow as input to the ram pump as well, it would offset a lot of the loss and hopefully keep the flow running for longer, long enough for the power to come back.

    I hope that makes sense.

    For me I have to move water up hill about an 8M head, so a backup pump either goes in the fish tank at the top of the slope, and if I have 3 fish tanks, I would need 3 of them I guess, or some other fancy plumbing. Anyway... I think this approach may work to keep a flow within the entire system for a while.

    What do you think?
