Sealand Marine Traveler with a secondary holding tank
We have an old Sealand 911-M28 and are going to "upgrade" it to the
711-M28. Through reading this group, I understand that one can install an inline pump to a secondary (larger) holding tank and have the pumpout rerouted to the secondary tank. Does anyone know how I can get more information on doing this? We have a 1988 Trojan F32 that my husband and I use it for cruising the Chesapeake and are tired of pumping out every 3 days. Also, the solution needs to be an economical one. The secondary holding tank in the V-berth seems perfect. Any feedback from those who have done this would be welcome! Thanks - Geri |

If you're going to put in a new tank, why not install a big enough one and remove the old one? KISS. You'll eliminate many possible sources of leaks & smell, as well.

Through reading this group, I understand that one can install an inline pump to a secondary (larger) holding tank and have the pumpout rerouted to the secondary tank. Does anyone know how I can get more information on doing this? It's simple: reroute the pumpout line to the larger tank...install a macerator in that line to transfer the waste. The 711-M28 Marine Traveler tank holds 9.5 gallons...a macerator pump moves 12 gal/minute. So I strongly recomend that the second tank be 20 gallons, which would hold two Traveler tankfuls. If it's smaller than 20 gals, you risk overflowing it...any larger (unless you go for 30 gallons, you either lose the additional capacity or risk overflowing it.

The secondary holding tank in the V-berth seems perfect. Any feedback from those who have done this would be welcome! My last boat was a 1980 F32 that bought from an estate and restored...they're wonderful boats! The v-berth is the ONLY good location on that boat. Any other location that has room for it is too far from the head. Route the hose from the Traveler to the tank under the portside hanging locker (the sole in the locker comes out by just removing some screws)--which is also a great place to put the macerater--and then behind the drawers. Run the vent off the tank to a new vent fitting near the bow...don't bring it back to the existing one behind the vanity in the head. And make the vent 1". Your best source for a tank is Ronco Plastics http://www.ronco-plastics.com They make TOP quality tanks for a very reasonable price, and have more than 400 shapes and sizes. And they install fittings in the sizes and locations specified by the customer when they make the tank.

Can you put a tee in instead of rerouting?

Thanks for the reply, Peggie. I appreciate your time! I sent an email
to you privately, but maybe it didn't come across... You said: "The v-berth is the ONLY good location on that boat. Any other location that has room for it is too far from the head. Route the hose from the Traveler to the tank under the portside hanging locker (the sole in the locker comes out by just removing some screws)--which is also a great place to put the macerator--and then behind the drawers. Run the vent off the tank to a new vent fitting near the bow...don't bring it back to the existing one behind the vanity in the head. And make the vent 1". Do you mean that the hose gets routed through the bottom of the locker past the v-berth drawer to the tank located in the v-berth? And...that the pump would be located in the bottom of the locker with the hose? Someone has been there befo Currently the hoses are routed directly through the locker (in the back) to a macerator in the v-berth. The hose from the macerator goes into the bilge and out through a thru-hull. The macerator (Jabsco 18950) is wired shut - we don't even know if it works. Looks like we need to: 1. install vents 2. reroute the hose from the macerator to the new tank after verifying the Jabsco works 3. route the hose from the tank to the pumpout valve. Does that sound right? Lastly - why shouldn't we use the existing vent? Thanks again! Geri |

Do you mean that the hose gets routed through the bottom of the locker past the v-berth drawer to the tank located in the v-berth? Yes. And...that the pump would be located in the bottom of the locker with the hose? Yes...or it can go in the v-berth if there's room. Someone has been there befo Currently the hoses are routed directly through the locker (in the back) to a macerator in the v-berth. The hose from the macerator goes into the bilge and out through a thru-hull. The macerator (Jabsco 18950) is wired shut - we don't even know if it works. Apparently the boat had a different toilet and a tank in the v-berth (which is where Trojan put 'em. A PO apparently replaced the toilet with the system you have now, and pulled out the tank. That macerator had to have been used to dump the tank. If it hasn't been used in at least 5 years, I'd replace it. Looks like we need to: 1. install vents Just one new one...your existing system already has one. 2. reroute the hose from the macerator to the new tank after verifying the Jabsco works Not quite. I'd replace all the hoses AND the macerator and start over to route them as I described earlier. There's no reason to have a macerator to dump the tank, 'cuz you can't legally use it in your waters. 3. route the hose from the tank to the pumpout valve. Does that sound right? Close. :) Lastly - why shouldn't we use the existing vent? Because it's in the wrong location--too far from the tank--to provide the exhange of air needed to keep the tank aerobic...which is the key to odor elimination. I tried emailing you to the address you post here, btw. Maybe that'll work. -- Peggie ---------- Peggie Hall Specializing in marine sanitation since 1987 Author "Get Rid of Boat Odors - A Guide To Marine Sanitation Systems and Other Sources of Aggravation and Odor" http://shop.sailboatowners.com/books...ku=90&cat=1304 |
