Deck Fill

Wilcox Crittenden -- stamped with 1 1/4 on inside of cap. The O-ring is 1" ID x 3/32" thick. Talking with them, they know nothing about these older deck fills, i.e., why do my o-rings get chewed up in six months, why the o-ring thickness changed to a thicker o-ring (wider groove in cap), etc.


Galley Faucet

Phoenix P5432A. Uses P82 washerless cartridge. O-ring for spout is a #11 (3/4" x 9/16" x 3/32").


Head Compartment

Faucet

Scandvik model 10443. Chrome flex hose (Scandvik 10286) is 6' long. I modified the sprayer holder by adding a small set screw threaded through the faucet body into a groove I cut on the sprayer. This setup eliminates the sprayer moving around from side to side while underway yet it's still easily removed for showering.

Do not keep the sprayer under pressure. The flex chrome hose will explode.

The connection to the faucet is via rigid supply tubes (copper) using a compression fitting. I had the rubber compression fitting blow off (10/2010). Replaced them with brass compression fittings.

Holding Tank

Holding tank -- triangular height (22" high, 21" base, 25" hypotenuse, 15" long). Volume is about 2 cubic ft. (~15.75 gallons). Vent hose is 5/8" x 8ft. (hose & through hull new, 8/1999)

Toilet (Head)

Raritan PH head (old design with multi-turn inlet valve). I removed the LWS spring on the input (9/98), which allowed more water into the head. I replaced the pump unit with the PHII pump assembly (3/1999). Rebuild kit: PHRKIIC.

Inlet pipe: 3/4" ID barb
Outlet pipe: 1 1/2" ID barb

According to Raritan, each pump stroke (i.e., up and down) of the PHII moves approximately 1 pint (approximately 1 gallon in 10 seconds). With 1" ID hose, 1 pint is 16" length of hose.

For PVC adapters to hose, see Sealand Technology. A 90 bend kit  for 1" hose is part number 307-230311.


Lectra/San

Raritan Lectra/San MC (installed 5/2001), serial number MC 004281 0900. Rebuilt 6/2009 -- electrode pack, motor seals.

Seawater -- 4.3 oz. salt per gallon of water (~4% salinity). Solar salt dissolves more readily than table salt and is cheaper! Add  cup salt per flush in brackish water.

10-12 pump strokes delivers about 1 to 1 1/4 gallons.

According to Raritan, use the Raritan Concentrate to deodorize and lube the system. Either use the metered system (TWK Kit) or add the concentrate to the salt tank.

Every six months, use muriatic acid (31% HCl) to clean the system per the instruction sheet.

The salt tank should be above the water line with a valve on the output to regulate the salt flow into the toilet. Too much salt will burn out the electrode pack!

To test the electrode pack, measure the voltage drop across the shunt on the control module (1" x 3" metal on forward side of tank). During the treatment cycle, the voltage should be between 16 and 26 millivolts. If the reading is noticeably less than 16 millivolts, the electrode pack is probably bad. You can buy Raritan Lectra/San parts from www.holtmarinesystems.com in Chester, MD.

I replaced the electrode pack on 8/8/02. The voltage reading was 11 mV. I replaced it again in 6/2009. The reading was 9.8 mV.

Replaced the macerator motor in 9/2012. The motor failed by effluent leaking into the shaft seal. The replacement part is 32-101AW ($240), which includes the motor, shaft seals, and shaft bushings. Raritan said that there's no reason to replace the cover gasket. I also replaced all the cover screws with Philips screws to make assembly/disassembly easier.

Maintenance

  1. Flush out system with three complete cycles and flushes of plain seawater.
  2. Flush toilet dry.
  3. Add one pint of Muriatic acid to two gallons of fresh water.
  4. Pour solution in head and flush dry without using Lectra/San
  5. Pour one gallon fresh water into bowl, but don't flush.
  6. Let it all sit for 45 minutes.
  7. Pump head 120 times with seawater (minimum of 10 gallons of water).
  8. Run a Lectra/San cycle.

Galley

Fresh water pump: Shurflo Model 8050-204-033. 1.6 GPM @ 30 PSI


A small air leak at the input to the pump will cause poor flow and pressure out of the pump. You can hear this leak when the pump turns off — it sounds like "fizzing" inside the pump.

Accumulator Tank: Shurflo Model 181-203 (24 oz.). Installed 4/01. Charge it to 20 PSI. Fittings 1/2"-14F-NPT.

Seawater pump -- Shared with washdown pump to a Scandvik tap (103100-RC). Ports 1/2-14 NPSM-Male

Foot pump : Whale Gusher MkIII Galley Foot Pump. Service kit AK0553. Piston & operating spring kit AS0556.

Whale Flipper Pump - Service kit AK0405

Washdown

Johnson AquaJet WD5.2  12V


Washdown Fitting

Installed flush-mount deck fitting to port of the windlass (6/2010). I bought the fitting from New Found Metals (www.newfoundmetals.com).

Apparently, but not confirmed, this is the same unit as the Jabsco 31911-0000.

Water Filter

Drinking water filter is plumbed into the cold tap at the galley sink. The filter housing is a GE SmartWater GX1S01C. Housing o-ring W3OSX10001 (3-5/16" ID X3-9/16" OD) or Culligan OR-38.

PENTEK CBC-10 CARBON BLOCK FILTER CARTRIDGE

Description Spec
Size 9-3/4" x 2-7/8"
Micron rating 0.5 micron
Flow rate 1 gpm @ 3.7 psi
Replacement 2,000 gallons
Purchased from www.waterfilters.net

Note; The GE filter (FXULC) has a restrictor that seriously slows down the water flow (0.6gpm). Don't use.


Water Heater

Heat Transfer Products SuperStor SS6M, 6 gallons (new 2005)

14" diameter x 16" high.

Pressure relief valve: Robertshaw Tempstat Model TP1100-1 Size 3/4"     75psi @ 210.

I plumbed the water heater from the fitting near the thermostat housing as the coolant source to the water heater. For the return, I put a T-fitting on the coolant return line from the heat exchanger to the block.


Water Tanks

Forward Tank - 64 gallons (measured, standard, not imperial). Clorox 2 TBSP.

Aft Tank - 25 gallons (measured, standard, not imperial). Clorox 1 TBSP

Recommended Clorox addition from Clorox web site -- 1 teaspoon (1/6 oz or 5 ml) per five gallons (however, increase this to per 10 gallons of water for better taste). One cap full is one tablespoon (TBSP).

With the family on board and showers everyday, we average 2 gallons per person per day.
