  1. Parts for an Aloha 32

    Gear & Maintenance
    I am purchasing an Aloha 32. BTW, thanks for all those who comment on an earlier thread about the boats. This one in particular is missing it's holding tank. Does anyone know where to find one?
  2. Toilets, Y valve or not Y valve

    Gear & Maintenance
    In process of rebuilding plumbing system on my 31’ sailboat. Present system has a Y valve between the head and holding tank, which also allows the possibility to discharge overboard via vented loop-macerator pump depending on position of Y valve. The hose from the head is connected at top of...
  3. Cockpit Draining - Below waterline?

    General Discussion (sailing related)
    I have an Irwin 41 that I'm gradually figuring out, but my most recent finding is that the plumbing from my center cockpit drain goes down into a seacock/thru-hull fitting uneder the waterline at the bottom of my boat. I don't quite understand this configuration. The cockpit sits high out of...
  4. Water Pump/Hot Water Heater/Breaker Trips

    Gear & Maintenance
    Two weeks ago, Sunday night my water pump started to run as it normally does. Then I heard a "click" sound from somewhere else. At that point two things happened. Hot water started to drain from the hot water tank via the pressure relief valve and the pump continued to run in a "slower mode"...

  6. Replacing Head Plumbing

    Gear & Maintenance
    I have a 12 year old Bene 331 and I'm looking to replace all the head hoses over the winter. Wondering who has had experience with this and more specifically: - Has anyone done a system with rigid PVC/ABS and flexible couplers? - Is there any downside to completely removing the Y-valve for...
  7. Software for wiring and plumbing diagrams

    Gear & Maintenance
    I have a couple of mid-sized sailboats to renovate and want to plan wiring and plumbing before I start. Also, when I sell one of these boats, I want to turn a set of diagrams over to the new owner. Any recommendations for free or reasonably-priced software (Windows 7 operating system)? The...
  8. Valving for overboard by macerator OR gravity

    Introduce Yourself
    I am replacing the holding tank on my new old boat and the new tank's bottom will be a couple of inches above the water line. I want to be able to discharge by gravity but there is a perfectly good macerator pump teed off of the pump out line about even with the top of the tank. There is a Y...
