If that is the case I believe your pipes down stream are blocked.
Is it possible to trace the pipe and check for tree roots etc that may have worked their way in?

Don't know where you are, but Everflo is a major brand, they have several types. It should be installed where it is protected from the elements. And then all plumbing ought to have a pressure check, because if it's old plumbing, new high pressure might be too much for it.
Otherwise, why not just use a bucket to flush the whole thing? A bucket that holds 11 to 13 quarts ought to do it. You can save a lot of water by peeing into containers and decanting onto compost pile.
