you need a set of velocity valves. these valves, installed in the manifold, replace the regular hose connection fittings, and will eliminate that drastic dropped feeling.
just detach the hoses, and replace the standard fittings.
one at a time, so the hoses don't get crossed.
the jacks are self bleeding, so just run them down and up a couple of times and you are good to go.
these valves do not restrict the flow when extending. only when retracting.
when a hwh system is stored, the front jacks retract first. then, after five seconds, or so, the rear start retracting.
that original drop is surprising, and upsetting to some, including my wife. these parts will eliminate that complaint. part number is RAP90280
