I had a similar footpump on my Catalina 36 and the water discharged from the fridge to the galley sink drain. I suspect that it is something that Catalina is trying on the newer 42 models because obviously the "Rube Goldberg" contraption on my boat is causing great confusion to some owners including myself. You are lucky with your simplefied system - it worked well on my Ca 36 (Hull #2152 - 2003 Model). It is obviously not draining into the bilge because as you said the bilge pump is not recycling.

The hose from the foot pump leads into the shower sump in the aft head. From there is is pumped out by the electric shower sump pump. You may be sending the refrigerator drain water to the sump without realizing it. Regards, Gene Fuller Yorkshire Rose, C42 #870

Both the head and the fridge drain hoses meet at a manifold just above the bilge. This manifold has two valves, one for each line. In the past I've left both open,... but I'll end that practice now and use only one at a time. I found the filter clogs quickly, especially if anyone uses the aft head for a shower or just tracks in too much sand or dirt from shoreside activities. To empty the fridge, I need to open only the fridge valve and through hull, then turn on the aft shower sump switch in the aft head. Same for using the shower except use the other valve. This should solve the problem I had of mystery water running under the floor board of the aft shower. (it came from the fridge) Jim Lee s/v Pure Joy #508 - 3 Cabin Pullman Tacoma

The outlet of the manifold is connected to a diaphragm pump located behind the medicine cabinet in the aft head and (I believe) connected to the same thru hull as the aft head inlet. It works fine. I have had no problem with the location of the antisyphon valve. I recently added a tee, an additional valve and a suction line into the bilge and use this pump to pump the bilge drier than the bilge pump. When I did this installation I also installed a strainer downstream of all the manifold valves. As reported by others, a lot of installation debris (e.g., dust from cutting holes in fibreglass, etc.) finds it way into the bilge over time. I've had to clean out the strainer on a yearly basis since installing and using this system to dry out the water that remains in the bilge below the bilge pump float switch level.

The pumps are the type that have the motor on top, and a crank and connecting rod to the diaphram portion of the pump. Rodney Kidd, C-42 #567 Sashay, 2 Cabin Fin, Marina Village, Alameda, CA

This system seems to be the least complicated and most user friendly They also e-mailed me a diagram for the 2 cabin pullman model-that drain goes from the fridge and icebox directly to the galley sink via the foot pump. Previous to this model year they have several different set ups with different types of pumps. They all seem to work, some more complicated (my system) than necessary and extremely productive to bacteria growth. that is why some owners have circumvented the drain system and simply routed the hoses to the bilge - which I hesitate to do. At my next haul out I will change my set up to the footpump system. It also means that there will one less thru - hull on my boat. That is in itself is a good thing. Since the drains are not used as frequently (because they are not easy to use) they have a tendency to encourage nasty growth, which equates nasty smells and bacteria. Bacteria so close to food storage is not good. So in conclusion; from now on I will flush the drain system at least once a month - vinegar has been recommended and will be used on the C'est la Vie. Thanks again for all the input/suggestions - I really appreciate it. Peter C'est la Vie Hull #746

When installing a new system I made the bottom the deep freeze and use a thermostatically controlled fan as a pump up for the cold air. Before the installation I added 2" of blue board foam covered with fiberglass to the bottom after glassing over the drain. It's been 2+ years and I haven't missed the drain at all. When defrosting the system I let it melt then use a big sponge to soak up the 1/2 liter of water that has accumulated. Nick Wigen Ursa Minor #178 FK, 3-Cabin Portland, Oregon
