We have completed a number of projects on our plumbing which should make our voyage more comfortable and trouble free.
We installed a Pur Powersurvivor 40E watermaker. It produces up to 40 gallons of water per day. Watermakers in general require considerable maintenance and this one is no exception. We have installed it so it is well isolated from our fresh water tanks and we can flush and pickle the Pur from a separate water tank. This is important we plan to use it only when it is needed. We had difficulty firing up this system because we had some small leaks in the saltwater feed line. Any air that gets in the system will cause the watermaker to make air instead of fresh water. This is apparently a common mistake of amateur installers so be careful. There is a new watermaker from a company in Sausalito, CA. The name escapes me but it will produce 200 gallons a day drawing 8 amps an hour. This is very impressive performance so look into it if you are shopping for watermakers. 40 gallons a day is only 1.4 gallons an hour. Our experience so far is that we can get by on 5 gallons a day but we still need to run our watermaker over 3 hours a day to keep up. Something in the 200 gallon a day range makes more sense to me in retrospect.
We have re-plumbed our head discharges. The forward head had a hose running back to the holding tank by the aft head and this line was bad. We have replumbed the forward head straight out which is a very reliable set up but we will be required to close it when we are in waters that require a holding tank. The aft head still runs to the holding tank but we have plumbed a macerator pump which allows us to empty the holding tank when we are under way in open waters.
We have installed a salt water washdown pump. It is a Par-Max 4 pump like our fresh water pump so it also represents a set of spares. We also cleaned up some plumbing left over from an air-conditioner we removed.
We installed a foot-pump in the galley to reduce our water usage. It also provide an alternate method of getting fresh water from the tank if there is a pump or power failure.
We have a Seagull IV water filter in the galley. The Seagull is very good at filtering harmful contaminants and chlorine from the water. Water tanks can become contaminated no matter how hard you try so this is a good extra precaution and it was already on the boat.
We have a filter system for taking on water that consists of a pre-filter that is a 5 micron filter followed by a ceramic filter with an activated charcoal core which claims to filter very small particles including bacteria. We will still treat the water with Microdyne after we put it in the tank. We only have 1 water tank which isn't the safest set-up so we have to be very careful.
