Water leak next to the pump

• 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.

i dont see why the whale one would know which type of pump sent the water.....of ypu dont get any joy from truma, od try the whale one.

Thanks for taking the time to reply, very much appreciated

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.

This was useful .. will replace mine with a whale one .. o
