Water Systems
The filtration system is fairly easy to install and can be added after the fitting out is complete. The fresh water system starts with a large tank, in our case some 2500 litres, that has a manhole in front and in which, at some point one has to climb in and spread a cement paint substance over every square centimeter of the interior. This keeps the water fresh, and is a process that must be repeated about every three years. You will need access to the manhole through a removable section of wall.
A pipe with a shut-off tap leads from the tank to a pressure tank and pump. The pressure tank maintains a reserve of air so the pump does not start every time a small quantity of water is used. We installed the filtration system after the pressure tank so the water is diverted to the forepeak for a quick cleanup before heading to the heater at the other end of the boat. The water heater is combined with the radiator heater system so we will report half the cost, 1,400 Euros, for hot water and half under Heating and Air Conditioning. The pressure tank and pump cost 600 Euros.
All the piping was instaled under the floor so it is an early consideration. The cold water system goes directly to the various taps from the presure pump while the hot water goes to the heater before distribution. We used Hep2O pipe and fittings for the fresh water because it needs no soldering or welding. The press-fit connections have not leaked a drop in our first year and we are well pleased with the product.
We included a bathtub with hand-held shower, two bathroom sinks, and a kitchen sink as the plumbing facilities. These cost a total of 3,200 Euros but we did chose some very nice fittings. A cost of a third of this amount would not be unreasonable.
In total we spent 10,500 Euros on the fresh water system. Above we have identified 8,700 Euros in costs to which we can add a further 500 Euros for the plumber's assistance and the balance of 1,300 Euros covers the costs of Hep2O fittings and pipes.
