[Amel Yacht Owners] Re: Replacing AMFA Fresh Water System by Jabsco

Fred,
Did you keep the accumulator tank? Or, does the tank remove the need for one?
With best regards,

Hi,
I can add another piece of
information to this thread. Just a small work to do is to prepare the pipes connection in order to connect with the in and out part of the boat.

Hi Mark,
I didn't keep the accumulator of the AMFA pump, just removed the whole thing and replaced by the Whale. I didn't notice any delay in the arrival of water… Of course the pump feeds as well the hot water tank. As explained above, the green light on the 24V panel helps a lot at viewing possible losses in the water circuits and avoid emptying the water tank without notice - I think it's really useful From our experience, the power of the Whale 24V is enough for fresh and hot water, kitchen or shower use. I'm thinking at replacing the anchor washer Amfa pump by a simple device like this one but I'm still thinking at a more powerful one because washing the chain is really pressure dependant… Did a member already experience the replacement ? and which model or pressure is convenient ?

On the subject of hot water, we have only cold on our 1980 Sharki. Can anyone show me where and how the hot water tank would be set up on a Sharki? It would be great to have a hot shower! Cheers, Warren and Zetta. Manon2 Sharki #15 Phuket

Warren,
I have bought Sharki #80 build in 1982 in April this year and I'm still working on it to make it a little bit better. There are two systems to make warm water and this is not state of the art as for today. I have found a warm water boiler in the engine room to make warm water with the engine cooling system. So it works only when the engine is running. Another heater with 220 Volts connection is below the kitchen sink which works when shore power is available. Modern warm water heaters as of today uses only one device like the boiler shown here from Quick. They get their heat from engine cooling system and/or from shore power as well. I will change this next year. Actually I have changed already the Jabsco WC to the better Lavac Vacuum toilette and next I throw out the old Frigoboat fridge which has two compressors: One with shore power 220 volts and one compressor attached to the engine. I will build in a Coolmatic fridge with 12 volts only. My batteries are strong enough and the Sharki has 3 alternators. |

Hi all, following this discussion and seeing all of the references to the GPM output to the pumps, but no one is talking about the pressure. I don't know how accurate the gauge is on my AMFA pump but it shows a pressure of about 30 psi or 2 bar. Some of the pumps discussed here are delivering 45 or 55 psi. It is the pressure that peels the sunburn off in the shower and blows your hoses when they get old. The GPM rating tells you how many of the faucets and showers you can run wide open before you get too much pressure drop.

I currently, with my old AMFA, don't run my shower full blast and and don't have significant pressure drop when we are running both showers. The pressure accumulator tank of course helps manage the pressure drop with the AMFA. I would like to add to my spare pump inventory and the Whale pump looks attractive to me from a price point. I am intrigued by the thought of the quick disconnects. It looks like it has good flow and I think that one was 45psi. Any other thoughts about the water pressure, or experiences with water line leaks or failure points? Dan Carlson, SM #387, sv BeBe

I use a parallel pair of Marco UPE2 gear pumps as my freshwater pump. They are much more robustly built that the other alternatives to the Amel original pump I have seen, but of course you pay for that. I have a fair amount of experience with Whale, Jabsco, and other diaphragm pumps and most of it has been not good. We have had the Marcos in service for a year of full time service and are very happy.
The pressure is listed as "29 PSI" and that is a maximum. We see pressures of 25psi in real world use. That seems low, but with good fittings (especially shower heads) it is more than satisfactory. The flow volume is more than we can use with two users fully open. Having two pumps in parallel means I have a built-in installed spare in case of problems.
