Re: The sump [Rog]

To the get dimensional details, I'll have to consult with the Engine's Mate who designed it, but here's the general idea. We have two "automatic" Rules. We use rigid PVC pipe as risers, which come up to threaded couplings (to make assembly and disassembly possible - it's a real jigsaw puzzle down in there). These then connect to manual shut-off valves - so that the individual runs can be isolate - then to a PVC manifold. The manifold then connects to reinforced hose that runs to the mushroom fitting on the stern. Another PVC pipe leads to the intake of the manual pump (which is located under the starboard quarterberth. Bad location, I know, and eventually we'll move it to one of the cockpit lockers, but that's a low-priority project.) We have check valves between the pumps and the rizers. They are bronze, and large (don't know the dimensions), and probably purchased at Home Depot or some similar non-marine source. One pump is mounted about a foot about the other, held in place by the riser. If everything worked as it should, we would leave both pumps on all the time. One of the pumps never turned off correctly, so it became the "high" pump, as the backup, to be turned on if needed. The bottom pump was left on and would cycle on and off as needed until it too stopped turning off, and we now have to turn it on and off manually. We'll probably replace one or both of the pumps this winter, and maybe see about getting a separate float switch. Not that I expect a separate switch to be more reliable, but it just may be easier and cheaper to replace when it inevitably craps out. Alfred Poor 1969 Cal 29 #132, "Pentaquod" What is the size of the output line from the Rule bilge pumps and what brand or type of check valve did you put on there? I've had the "won't shut off all the time" problem with my Rules too. Can you give us more details in how you set it all up? Thanks, Alfred. \Rog
