Hot water heats up on gas and electricity to proper temp, tested by relief valve.
By the time it gets to the outlets, it's luke warm. This happens on both mains water and caravan tanks. The taps are running for a while and still Luke warm. Pressure is down a bit but has improved since I moved the sludge out of the tank and checked the anode.
Highly frustrated and starting to smell, it's cold down here. Thanks in advance.

Phil,I had this problem 5 years ago when I purchased a new van.I resolved it by removing the tempering valve from the water circuit.These valves are required to be fitted by law to all new vans to prevent hot water scalding the unwary.It is situated somewhere under the van,has two inlets ,one straight from the tank,the other from the cold supply,thus providing a lukewarm mixture out the third orifice to the hot tap. There is an adjustment screw under the plastic cap but it makes little difference. The unit is easily removed and certainly within your capability.It is great to have piping hot water in the sink and in the shower,so get out the groundsheet and have a poke around under the van.follow the hot line from the heater and you will come across the brass valve. Hope this solves your problem. Ian

Hi
99.9 % it will be the tempering valve problem
You can take it apart and clean

Found the tempering valve and have (as a first step) blocked the cold feed. We are getting a bit more than a dribble from the taps. I may have to join the hot hoses together. Thanks guys, great advice. Will keep you posted.
Cheers

Have you checked the temp on the valve, my valve was at the max and very hot in the shower so turned it down a bit so now have the tap fully open and water temp just right

In my old van I cleaned the tempering valve when i had your problem - only problem when I fixed it my wife used too much cold water to cool the hot water down - next time I had a problem I told her it could not be fixed and our water supply lasted much longer when freedom camping!!!!!

BINGO!!!!
The offender (tempering valve) has been relegated to the dustbin, the pipes joined (just a bit heath robinson, but it works) and I have just enjoyed a nice hot shower. I will be doing some final fixes when I can find the proper bits (eg copper tube and john guest fittings.
Thank you so much for your sage advice folks. I had no clue as to what a tempering valve was but you guys did the trick.
This is one very powerful and useful forum.
Thanks again folks, very much appreciated.

Three John guest joiners should do the job Phil.Follow the cold feed back to where it comes off the main cold line ,remove the T piece and rejoin with a new joiner.Use the piece of pipe you take from the T piece and the other two joiners to complete the joining of the hot line.You might have some pipe left over and keep the T piece for a handy spare. Ian. Happy showering

As I said -now your showers are going to get longer ("I have just enjoyed a nice hot shower.") - Then the water will run out - put in bigger fresh water tanks or reconnect the faulty tempering valve LOL. Glad your water is ok - but on most tempering valves you can clean them and they will work as intended

Another trap for the unwary, when i received my new Jayco i found that the hot water temperature as measured from the Hot water heater pressure relief valve was about 60 c but from the hot tap only a trickle of luke warm water. Two problems: 1) Tempering valve as discussed (if you remove the cap you can then adjust the valve) Leaving the cap on just freewheels and it on has no effect. 2) My outlet pressure when I got home and connected mains pressure was woeful, it wasn't the water low pressure at Narooma that was to fault as first suspected it was the restrictor valve that drops line pressure down to a manageable levels when connected to mains. So if pressure is OK with pump but poor with mains replace the valve. (its not adjustable and Jayco kicked the can for the new one) Last note with Jayco vans there is a valve that controls the line pressure from the water pump, this may need adjusting. Really pleased that the forum continues to solve lifes mysteries for many of us. I would like to remove tempering valve but worry the grandkids may end up scalding themselves.

Gday Brian,
Im pretty sure thats why the tempering valve is installed. I spoke to a caravan repairer yesterday when I bought the connection bits to neaten up and finish this job. He claimed the standards and lawmakers installed these critters in houses to do just that, but in caravans a whole new can of worms.
Appreciate your comments re the pump pressure adjustment, will set up when I have finished my crawl under the van.... AGAIN!!! lol
Cheers

Just an aside to this conversation, we had the beautiful hot water starting to surge and cause a few problems. The valve you mention needed to be turned down oddly enough to bring surge in line. Now constant hot water 100% agree Brian D this is what this forum is all about.
hi all
This little problem is driving me nuts.
3 year old caravan we live in 24/7.
Hot water heats up on gas and electricity to proper temp, tested by relief valve.
By the time it gets to the outlets, it's luke warm. This happens on both mains water and caravan tanks. The taps are running for a while and still Luke warm.
