Water in ensuite cupboard

In the last day or so we have discovered that water has been leaking into our lower "waterproof" cupboard in the ensuite. This is the one at floor level and under the hand basin.

There is no obvious leak in the plumbing and we are still trying to work out where this water is coming from. High on the list of possible sources is the outlet for the Dometic diesel heater ..... our van is about 14 months old and has the heated towel rail type outlet here. The large lower vent could allow water to enter and the flex air supply pipe is not sealed into the back end of this outlet so this water could trickle through and into the bottom of the cupboard.

Our original towel rail heated outlet had seized up and was replaced by Bushtracker ( under warranty ) in September. Maybe the original flex air supply pipe / ensuite outlet join was sealed but was left unsealed on replacement.

Can other owners throw any light on possible source of the water leak OR check if their flex air supply pipe is sealed or loose fitted to the back of the towel rail vent.

Thanks for any assistance you can give.

Hi Brian & Dianne
We did have a water leak at the backing plate for the shower flickmixer. It's almost impossible to get a good view (my head wouldn't fit in the door space!), but I used my old dental skills and viewed it indirectly with a mirror. There was a slow leak at the joining thread with the telltale water stains on the plyboard. It was just a matter of replacing the sealer tape and resecuring the thread - no more leaks in 4 1/2 years.
Good luck.
Enjoy Tassie- a great time of year to be going!

I don't think it will be a problem with the heater. The heater uses internal van air and heats it up before delivery via vents etc. The heating of the air should allow it to carry more moisture. Cooling the air could cause condensation but not heating.

I would be checking for water pipe joins.

G'Day Brian & Diane,
We did have water appearing on the floor in the ensuite cupboard. Could not find the source for ages. Only happened when it rained and then not always. We have an external shower ( That we've never used in 5 years ), finally found that water was seaping in the top of the unit. Wayne at BT fitted a piece of angle just across the top and we haven't had a problem since. He said that because of the material the shower unit is made of,they have trouble getting it to seal to the aluminium.

Thanks for the info guys. We have checked out all suggestions ...... and a few others but we are still none the wiser as to where this water is coming from.

BobH ..... can't find any leaks in plumbing / fittings etc but will keep looking. I think this has to be the problem in the end .... maybe when the pipes are hot ? Big head does not help in these tight spots ..... led torch on head helps. Have been to Tassie before but had to miss so much as 8 - 10 days only ...... hope to see it all this time.

Alan .... I was concerned about excess shower water splashing into the lower heater vent in bathroom and entering the cabinet that way ...... have checked this out further and probably not. As you say I think plumbing may be cause.

Lawrie ...... We also have the external shower ( not yet used ). It looks to be sealed OK with plenty of sikaflex there but will keep an eye on this.

Will post again when we find the problem.

Tip for all,

Check to see if you have the same hose our van did from T piece to Ex shower.

If so replace it with the correct high pressure / high temp type, not a fun job ;-)

Hi Brian and Diane

You made have a later version, however if you have a town water inlet (the old style-screw hose fitting onto van) which comes through the side of the van into the space under the vanity then it will be the fitting on the back. There are 4 screws on the back which require tightening regularly. Even when not connected to town water they tend to drip from that fitting.

Also check the tightness of your connections.

I can now see water accumulating on the HWS timber tray/shelf ....... at the back of the HWS very near to the bottom connections. Not sure if it is the screw in connection to the bottom of HWS or the hose connections to this fitting. This is looking down thru the top waterproof cupboard with removable shelves out.

Strangely this water only accumulates here whilst the water / shower is running and not at other times. Immediately after a shower it is quite wet but then quickly dries our due to heat generated by HWS and remains dry til next shower. Some excess water drips thru the gas pipe hole and to the floor of the cupboard where the dampness remains.

We have the new type red & blue water pipes and the white click type fittings ...... all these appear to be secure and as yet am unable to find the actual leak. Our layout will not allow such easy access as Mick has enjoyed so we may have to get Bustracker to remove HWS to tighten / check fittings. We are not that far away presently. Is this still under warranty at 14 months ???

Once again .... thanks for all info .... will keep you informed.

Contact Wayne at BT and explain problem and I am sure he will fix it under warranty.

A bit of tissue or toilet paper wrapped around any suspect leak areas will reveal the source of leaks that only happen when you are not watching.

Thanks for further info Alan & Bob.

We now realise that this leak is occuring when the HWS water is being heated. The pressure buildup is being released at the leak point ..... the lower screw in fitting at the rear of the HWS which does not leak at any other time.

It appears that the HWS pressure release valve is no longer operating normally. This valve has been working in the past as was evidenced by dripping water at the overflow point. Even now, when operated manually, it allows water to flow freely from the overflow pipe.

We have been in the habit of leaving the HWS to reheat as required but will now use this to heat on demand until we have the problem fixed.

We intend to refer the problem to Bushtracker and see if they will repair it under warranty as van is only 14 months old and, judging by cupboard and contents damage, the leak has gone unnoticed for the past few months.
