Twin 600
I have just purchased my Twin 600. I have taken it back to where I purchased it so many times and they are not able to help.
I take the van to a caravan park and the water flows and everything works perfectly. Hot water, sink, toliet. Around 2 pm like clockwork everything stops. No hot water, Toilet shower nothing to do with water is working.
Usually end up just going home in the morning totally frustrated.
Fingers crossed someone out there has a simple answer.
I live in Sydney Australia so frost is not the cause.😀

As a starting point, try setting the clocks on any control panels you have got an hour different and see if the time the pump stops working is an hour different
I once had a problem setting my heating to come on in the morning and it was because the Alde controller was set to the wrong time (it wasn’t displaying ANY time, which is why I didn’t realise)
Not quite the same as your problem, but may help narrow things down?
Sorry, just seen your post which says the pump IS running, so not the above!

If this happens regularly, how are you remedying the issue in between failures? If its by refilling the tank, are you simply using up the limited on board supply?

You say you're attached to the camp water supply - is that a pressurised system that's supposed to bypass the on board tank or refill it? If yes, there will probably be a couple of valves that need setting correctly to facilitate that. If they're not right, you may only be accessing what's in the tank and thus running out of water.

Edit ...... one other thing: check the drain valve is shut.

Hi Michael and welcome to the Fun!
:welcome3:

Does this only happen at this one campsite? If so, could something happen with the site's water supply at 2pm each day (switched off for some reason?) that your van subsequently needs something to be reset as a safety precaution when the water supply comes back on?

Does the system work normally when you use the van away from any fixed water connection, ie just relying on the tank?

I have found the below information about a pressure adjuster on a product review site which may or may not be useful. It relates to caravans rather than motorhomes, but it is Adria and it is Australian! Perhaps someone on here can advise if it has any relevance to your problem.

Welcome to you all the way down under.

I am not aware of anything timer based except usually heating and hot water on vans for this market. However as both hot and cold water are affected,, and you can hear the pump running, it's difficult to think how those timings could affect things. I suggest you check the settings for heat and hot water o see if anything is set to switch on or off at around 14:00. Make sure the clock is set to the right time first though or allow for the offset.

Are there timers for things like air conditioning that are not common here? Again, if so, are there events set for around 2?

Are you going to the same site, or even pitch each time? If so, and you are on a pressurised connection, is that going off? If you have the van at home, does it do the same thing?

What is the dealer doing to put it right? They really should be leading on this as you are new to the game, so you might want to get a little tougher with them.

Sorry, loads of questions and no answers, but unless its just that you have emptied the on-board tank as suggested by Trevor Wbm, it has to be either the incoming supply is off, or something else is triggering the problem. Only way to find out, is to work through things a step at a time.

Good luck and keep us updated. Normally another Funster would come running to your aid, but I don't think we have any active members in Australia, and it's a long way from here.

It sounds like an external issue to me.

Does the water company/campsite drop the pressure at 2pm every day ?
(Which means not enough pressure to run your taps)

I'm guessing when you are plugged into the campsite water, you are bypassing your own water tank.

If you fill your tank, then when the campsite pressure drops you can use your own water ?

I'm also guessing you pay for water usage.
Is it possible the meter cuts out at 2pm unless it gets another payment for the next 12-24hrs

(Shortage of water is not a problem in northern Europe, so we have no campsite water meters,
and people have no issue with dumping half a tank of fresh water to drive to the next place and fill up again)

Could be for example the irrigation sprinklers come on at that time, so the pressure drops enough to make the van system assume it's been cut off.

My take is that once water goes off it does not come back on... as it would if sprinklers, and OP says he gives up and goes home next morning???

So a 2pm you get no water coming out of any outlet, but you can hear the pump still working??

Yes
The hot water is on I can feel the tank hot.The pump is on and is working but nothing is coming out of the water taps.
It has happened the 4 or 5 times I have used the van so it is a regular problem. I asked someone at the caravan park once and they had no idea what could be the issue.

You're upsidedown😭.
Seriously, have you tried regular use of your water system while at home to see if it happens no matter where you are?

I have not tried it at home. I park in a service station and dont have access to water. I will try that next week when staying at a friends place.
Never know.

That's what I wa thinking. Its the only logical explanation.

Just for the record, connecting directly to the water supply in the UK would be an offence as it would not comply with the bylaws. A motorhome does not have approved fittings and a approved check valve would have to be installed .

Does this happen to other people on the campsite? Do they have a similar water system to yours? Most UK motorhomes have a fresh water tank, maybe 100 litres or so, that is filled at intervals by a simple hose sending the water into a filler hole, or by carrying water containers from the water tap and pouring them into the fresh water tank.

A few have a system where the tank is kept topped up by a hose, with a float valve to fill when the tank level drops, and cut off when the tank is full. Others have a direct water mains input, usually with a pressure reducer. This bypasses the fresh water tank and goes direct to the van plumbing, with a switchover valve to use the fresh water tank when mains water is not available.

Is it possible to disconnect the water hose at the campsite connection point, and turn on the tap to see if water comes out of the connection point after 2pm?

Is your pump the type that's submerged in the water tank or located elsewhere in the m/home, e.g. in a locker?

If it's an Adria Twin 600 (as he said) should be a Reich submerged pump(y)
This problem is really weird. What does it mean being attached to the water? (as gpat asked) Don't see a connection with the issue:unsure:

Ah, I'm not familiar with the Adria.
It is a very odd occurrence but I think the 2 o'clock timing is purely coincidental.
The OP says he's very new to it and I have a feeling that the issue is something very simple
