How To Fix & Replace John Guest RV fittings

[@man.i.literally.failed6772]

Best thing I did was put 1.5 laps of tape on the sink mixer connections, they say not to use tape but when I got my new van everything was leaking, now it's not, and I'm also not a fan of connecting main hose to the van. I carry about 3m of each hose color, and have a emergency kit ( cost me $160) with all types of clamps and fittings.

Thanks Barry. They are prone to crack and fail even without the tape. We have toilet paper secured around all fittings and pipework so one can readily identify a failed fitting as we nolonger leave the pump turned on when not using.water and we nolonger use direct from tap water supply that won't stop if there is a failure. We listen carefully to the water pump when we turn it on to see if it let's us know there is air in the line and hence a water leak. All our plumbing is between the two floors or in the cupboards or walls and so the leak can't escape to ground, rather it wets the timber construction should we not notice. So we have become somewhat cautious after a couple of failed fittings.

Our first one was the hot water outlet from the Truma HWS. We’d been travelling and stopped for afternoon tea, only to find water running out from under a bed , where the HWS was. No warning - so it’s off with the 12v water pump when travelling. Not a big fan either of hooking the mH up to mains water.
