Thanks, Richard.  Do you eliminate the pressure/accumulator tank(s) when doing this?

We just changed out the pump and tank system on another SM to an on demand pump to halt just on off problems and save battery life as well. It works great. We also replaced the AC salt water pump with a March pump. Smaller and sealed. With water cooled bearings.

Hi, all,
I've been looking at the link Eric sent about our fresh water pumping system. There is a tremendous amount of info on this site and I recommend that you save the link.

I have a short-cycling pump on Kristy (SM 243) now and will be trouble shooting it next time I get back on the boat. I have a couple of questions about our Amel systems:
1. Is the pressure tank at the pump one that has a bladder?
2. How does the additional reservoir/tank above the water heater add to the system?
3. What are the common problems you've found with our systems?
4. Since our pressure tanks are small compared to the ones featured in the site at Eric's link, I'm not sure how long it should be between pump cycles. It's always been 10-12 seconds on my boat until now, but I'm not sure that's what it should be.

The pump that was on my boat when I got it wouldn't turn on at all, so I replaced it with a spare that had been purchased by the original owner. I haven't had any problems for 5 years now until now.

Thanks for your thoughts/advice.

Hi Martin,
There are two adjustment nuts underneath the grey plastic regulator cover.
No 1 is the range nut, No 2 is the differential which should set the flow
pressure. Then adjust the first one to set the "cut in" and "cut out". The
factory setting is around 20PSI .
There is a comprehensive explanation sheet on
Inspectapedia/water/WaterPumpAdjust.htm
If you can't find that I have saved it for you. Email me using my full name

Thank you for your reply which solved the problem. Filling the pump

housing through the vent plug was enough to get the system going.

My delay in replying was due to my wanting to post the identity of the

replacement accumulator tank that AMEL supplied to me.

It is a SHURFLO tank and appears in the USA in the West Marine catalogue

for 2013 on page 482 as Model 492739 with a price of $324.99.

It has a female fitting unlike our original which was a male fittign but

standard adaptors bridged the difference. The top plate requires drilling
for the Reya pump. I also had to replace the rubber mountings and the ones
supplied by AMEL had a larger thread so the mounting plates required
drilling and tapping to take the replacements.

The new tank works well except that the pressure has to drop right off

before the pumop cuts in. Any advice on how to adjust the pressure cutout?

Martin,
I forgot to mention that if you have a Reja pump, you most likely will

have to prime it. Take off the hose from the fresh water reservoir and fill
it with water, there used to be a bleed bolt on the top of the pump that you
need to loosen until the water is free flowing from the reservoir.

Good luck.

I have searched the postings and not been able to find an answer so

sorry if this is a repeat request.

After leaving the boat in Norfolk, Virginia, USA for 6 months we are

up to our ears in antifopuling, polishing etc prior to relaunch. I have in
the midst of this fitted a replacement accumulator tank to the system. The
original had rusted and was leaking air.

Note for fellow travellers, the replacement supplied by AMEL comes in

Shurflo packaging. Made in Italy, shipped to the USA, back to France and
then sent to us in the USA. If anyone is interested I will post the Shurflo
model number, just do not have it to hand whilst writing this. Also note
that the original (Amel 54 no 56) had a male fitting and the replacement has
a female fitting so adapters are required.

I have now put the whole thing back together and am not sure how to

bleed the air out of the system. We also have an empty hot water tank as the
boat had been winterised before I carried this out so there is a lot of air
in the syatem.

Grateful for any advice please.
