I have a jayco stirling poptop. Whenever I connect the water hose there seems to be a build up if pressure and the hose comes flying off. When bought van I was told just connect to van and I don't need to have pumps unless using tank water as there is a main line . If there something I should be doing that I'm not. We free camp a lot so don't often connect hose to van but whenever we do the same thing happens .

Comes flying off which end.
Check that one of the little pieces in the connector hasnt broken Usual reason for hoses flying around

If it is the usual garden hose snap-type connector, this is not unusual. It may be worn or a miss-match.
Replace both connector parts, male & female, and ensure the new ones are from the same brand. These things are not identical between brands and a miss-match often makes them unreliable at pressure. Have often had the same problem in the garden.

Me thinks Allen is on the money. Fittings must be matched from the same manufacturer

My first thought was that a clamp or something was missing. Then you may be right Allan. Those quick link type that have been around seem to have a standard for each manufacturer.

This is why we changed over to the Hoselink fittings all around the house. They don't leak or pop off.

It comes flying off from the caravan attachment not the tap end

What sort of attachment is it? If a 'click' fitting see above. If it is a screw on, where is it flying off.

Hoselink make a very good attachment that does not fly off nor pull apart.

I've had the same problem in a few places but generally just reduce amount that mains tap is turned on to what is a useable amount flowing from inside taps. Also saves undue pressure on the internal piping joints and tubing as they don't use particularly high quality pipe.

Phil, that is a furphy. Turning the supply tat on just a little will reduce the flow of water available to the van when when you turn a van tap on. However when you cease drawing water and the flow stops then the pressure will build up to the mains pressure in your hose. Just think about it, it does not matter how small the hole is between the mains supply and the hole, the pressure will build up through that little hole until equilibrium is reached both sides of the tap.

If a simple constriction in the pipe would suffice as a pressure regulator then you would not have to pay $126 for something like this


Years ago Coast to Coast used to sell pressure regulators that fitted onto the park hose taps. I purchased mine for $40. They ceased stocking them when the price rose above $90. You could try some of the plumbing shops for one. You may have to purchase one without fittings and add the hose fittings to it..

I sometimes have the same problem if the water pump is still turned on, maybe your pump is on also. Ours is a Jaco also

If the hose connectors are the problem then get some good quality brass ones and fit them to the hose. This perhaps could rectify the problem for you.

I have bought some good brass ones, as a kit for a hose, from Aldi from time to time at a reasonable price.

Another thing worth adding is that you can get a pressure reducer from nearly all plumbers suppliers. They are usually brass and are a reasonably small size.

The 1/2" variety are all that is needed for the average caravan. Get the lowest pressure on offer.

Also the shore pressure inlet for the van supply enters the system after the pump in the pressure side of the water service in the van so having the pump on or off should make no difference if it is set up correctly.

I guess you missed the earlier question. What type of fitting is it? A photo would help.

Not turning a tap fully on reduces the flow NOT THE PRESSURE. You need a proper pressure reducing valve for that.

Is a popular misconception.

So where do I get a pressure reducing valve from snd is it a hose attachment or something that. Needs fitting in the van

You may be able to get one at a plumbing supplier. however they will come without tap/hose fittings.

Matching hose fittings was mentioned above. This may solve your problem. However if the fittings have been OK for some months and then start blowing apart I have found that all you need to do is to change the 'O ' ring on the male fitting. Works for me most times.

Back in the dim-darks when trickle irrigation was starting to be used in domestic situations there was a hard plastic pressure reducer available to stop the trickle lines from waving around everywhere when mains pressure went onto the lines. They were not that dear (around $20 in them days) but did the job quite well.
A look at an irrigation supplier may turn up other options.

Don't forget to cut an inch of the end of the hose or the same thing may happen. I would tend to agree that a pressure valve is not required when turning the tap does the same thing and you'll have less joins in the line for water to leak from. If all else fails I would also highly recommend Hose Links fittings I have them at home and their great they also have an adaptor so you can still connect to regular hose fittings.

Turning the tap less is NOT the same as a pressure reducing valve

It doesnt matter if you turn the tap 1/4 turn or all the way the pressure is still the same regardless.

The FLOW is altered only.

This is an urban myth and easily proved to be incorrect.

We had high pressure problems in a house we owned and got a plumber to put a gauge on the outside tap.
It did not make the slightest difference how many turns the tap was it remained at the same pressure..
Had too install a reducing valve to stop the kitchen mixer leaking constantly.

I know all about the pressure equalising from the tap to the nozzle but Urban myth or not I must be the luckiest or the only person in the whole world this has worked for in the past. I've used garden hoses that blew the nozzle off at full pressure then if I reduced the pressure significantly the it stayed on go figure.

Batts the reason may be that by reducing the flow rate you do not get the big shockwave ( water hammer) that is created when you turn the tap on and off and that is what is blowing the fitting off
It is true that turning the tap down will only reduce flow, pressure is different and will remain the same
So you problem is caused by flow rate not pressure and so may the OP for that matter.
They are two different things and potentially two different problems for users
