WC vented loop and sea water filter We always close the sea cocks when we leave the boat, but once in a while friends are using it. In order to avoid accidents I have now fitted a vented loop on the intake side, which solves the issue. Also, the sea water filter for the engine is right next to the seacock. Modern boats tend to have it above the waterline. This is not straightforward to achieve on our 411. The only benefit I see of having it above the waterline is that it is easier to clean the filter, since it is not necessary to close the seacock. Any views? Christian IF 411/028 |

Chris, I had the same problem but fitted the new locking pump on the Jabsco toilet which fixed the problem. If you have the time and energy fitting an anti syphon on the shower sump discharge is worth considering.

Thank you John - strum box verification is now on the todo list. I watched Robert Redford in All Is Lost pump for one day at the helm with what looked like the same Whale Gusher that we have. That he first needed to prepare a wooden stick as replacement for the metal lever he had lost was to show that he like many sailors had started to rely completely on electric power. Christian |

Chris. We have a Vetus water strainer fitted to the engine cooling water intake, on our 411. the strainer is located in the locker above the engine compartment, in the aft cabin. it fits neatly in the lower part of the locker and is above the waterline so can be cleaned without closing the seacock, as designed. this has a much greater capacity than the older type strainers fitted adjacent to the seacock. It can also be checked much more easily. Paul . Hierro 411 042 |

Daniel. Yes, the intake hose run is longer than the original. The hose runs from the seacock, following the original route through ther engine compartment bulkhead, then down the starboard side of the engine, to a position at the stbd, aft end of the box. It then rises into the locker. The return follows a simlar route back to the pump inlet. The strainer was fitted when the original Perkins was in installed. I have replaced it with a Beta 50 and kept the same arrangement. It obviously takes up some space at the bottom of the locker however I think it is woth the loss for the improved filtration.

Phillippe. You are correct there must be more resistance on the pump suction due to the longer hoses. However the Vetus is sealed, unless you remove the lid for cleaning, so there is little air to be drawn into the pump. If you watch the water flow through the transparent lid, there seems to be no delay to the flow, on starting the engine. I have always changed the impellor as a precaution every year. There seems no additional wear with the Vetus unit. Regards Paul |
