  2. [Amel Yacht Owners] Alternating hot and cold water in showers

Hi Mohammed,

Thank's a lot for your suggestions. The hot water plumbing route is more restricted than the cold water. This can be a understandable case. I have never thought about it. I will have a look tomorrow and on Monday I will ask also the AMEL guys here in La Rochelle.
First I will examine if the pressure decreased during winter pause in the water tubes. If this would be the case, then I think, I should have the same effect also on all other water taps as in galley, sinks in the bathroom and so one.

Many thanks for all these good suggestions which give me a funny Sunday job. Let's hope, that I will find the solution.

Fair winds,

Philipp

Hello Philipp;
 
I'm not familiar with the exact plumbing on a SM. However, since most plumbing should be similar, I can think of two possibilities:
 
  1. The hot water plumbing route is more restricted than the cold. This could be anywhere in the lines, the water heater, etc. Therefore when the pump is running and you have increased pressure in the water system, there is more pressure in the cold water line than the hot. This would result in more cold water pressure at the shower valve, resulting in colder water.
  2. If the shower valve has been changed to an anti- scald one, the anti-scald mechanism may be failing. I believe this to be less likely.
Keep in my mind that I am not familiar with the SM plumbing and systems in any way. These are just a couple of general suggestions.

Hi Philipp

That sounds like you have no pressure on your accumulator tank. Between coldwater pump and hot-water-tank you will find the accumulator tank. You can check the pressure via a valve, like car tires. The recomended pressure you may be find in a tank manual. What cold water pump model do you have?

Hi All owners from "old" Super Maramus,

I have the situation, that on my SM #124 I have alternating hot and warm water in the showers. The cold water is this season in La Rochelle real cold, that I feel it very directly. Each moment, when the pressure pump is working, the cold water arrives and the warm water gets cold with the effect, that you get cold shocking moment for some seconds and afterwards the warm shower water arrives again, till the water pressure pump starts working..

Does anybody have an idea how I can eliminate this strange and uncomfortable effect?


Thanks a lot for any suggestions.


Fair winds,
