Ten minute job: Renault van is set up as a camper, attached to the passenger side rear door is a shower head. Open out the rear door and have a hot shower, nice.
This takes water from a pump, pumping hot water from a tank under the van, which is heated via a heat exchanger, connected to the vans heating. I set the temp to 28c, the water pump recirculating the hot water turns off at set temp and cuts back in at 24c.
But, the switch for the shower head pump has been inside the side door for a couple of years.
Fine in summer, finish showering and close valve, walk back to side door and turn off the pump. But in winter, you need to be partially dressed to go to the switch, rather inconvenient.
All I needed to do is run a two core flex from switch near door, wire it to another switch and hey presto; turn of water valve and then the pump from a switch mounted near the valve.
Work on that started at about 10am and I’ve just finished, almost 3:30pm
Wiring went fine, simple. But, on starting the pump saw no water at the shower head FFS.
Tank was empty, filled the 50lt tank and FFS, dripping water from the outlet barb!
1.5 inch outlet sleeved down to a 13mm barb, about 4 reduction sleeves.
I couldn’t be sure, where the water leak was, so redid every threaded join with plumbers tape.
Finally, back together, refilled ….. drip drip drip FFS
Heading north to see Shajota and then a Ducati mate

further up, this weekend, needed it sorted. Another two attempts, same outcome.
I’m laying underneath the van watching the drips, wiping dry as I watch
Thats when I spied the water drip coming from the inside of the tanks insulated outer.
The van was parked on my slopping driveway and the tank so full, the inlet pipe breather was dripping water into the insulation, down onto the outlet fittings, and onto the ground
