Water leak next to the pump

Dear All,

Help!  Our family are loving our motorhome experience, three full seasons now completed.  It is fair to say that my complete lack of technical ability has lead to a few bumps in the road - but I am learning!  I decided to do the correct thing today and drive my motorhome, bring it back home (we store it elsewhere) run the heating and generally make sure things were OK.  Once I had put some water into the tank I went inside to make sure the hot water tank was filled prior to putting on the heating.  After a while I heard a dripping sound and then noted a fairly significant flood on the floor.

Please see photo, the thing to the right of the pump was spraying water out of its top.  I think I now know it to be a surge damper, although I cannot find the exact part online.  What I am confused about, is how this supposedly hollow cylinder is full of water?  The system had been drained prior to storage and there is no obvious exterior damage to the part.  Could there be some frozen water somewhere in the system?  Now that it's full of water is it broken and do I require a new one?  Any thoughts from the collective knowledge out there would be very gratefully received!

Thanks

    • Yes , it is a surge damper and probably a Truma part. You are also probably right that is has cracked due to frost damage and will have to be replaced. I had a similar hairline crack on an inlet which was not easy to see. Looking online it seems that Truma have changed the design and are now charging around £125.00 for the new model. I could not find any of the model on your photo in stock anywhere. The Whale equivalent is only about £25.00 but  its probably not compatible with the flowjet pump and Truma system.

    You could try ringing Truma at Burton on Trent for information on availability of the model you have installed.

    Thanks for taking the time to reply, I very much appreciate it.  I'll do some phoning around tomorrow, particularly as the Whale one seems much cheaper...

    Agree with 'BB', the expensive Truma damper has incorporated pressure switch control which you do not want. The Whale is just a buffer reservoir as is your existing Truma unit, go for that.

    Water filters can also be prone to cracking in extreme cold. I had that problem on one of my yachts.

    To be on the safe side I'd also change the connecting T piece joint, as that too could be cracked.

    As a temporary measure , remove the surge damper and use a short length of pipe and joiner / end stop.

    Maybe just slowly turn taps on and off until the part arrives ;-)

    The surge damper will always contain some water and unfortunately this doesn't empty automatically when you drain down. I always remove it and shake the water out after draining.

    Don't forget unless you have blown through the pipes there will still be quite a lot of water trapped in the pipework.
