Toilet emptying
Just returned from Rookesbury Park. I empty my toilet daily. I started by using the CCEP point on the lower toilet block. The rubber hose was very short and as a result I damaged my Thetford casette. Luckily at a cost of £45 I was able to rectify the problem. I then looked at all the other CCEP emptying points and found the rubber hoses were of various lengths. I used the one by the upper toilet block after that.
I spoke to a warden about my problems and was promptly told that the length of rubber hose was specifically determined according to a manual set out by the water authority. Likewise the attachment on the taps which invariably spray water everywhere when used are also a statutory requirement.
I do not believe that the length of hose is a statutory requirement. I think it is rubbish and I'm being fobbed off.
Also if the strange device which apparently prevents 'blow back', whatever that may be, wastes so much precious water as well as being inconvenient why is the club not taking action as the water we use is on a metered supply and therefore water spraying out costs us money as well as wetting us through?
Anybody got any explanations or thoughts?

Sorry, my thoughts would not pass the moderator.
Did you have a good holiday?

Morning
The explanation by the warden was correct. The installation of the "nabic" valves on our sites, although slightly wasteful on the water side is a legal requirement so I'm told. The length of hose will vary. Strangely, we seem to be the only company that uses them!
How did a hose do £45 damage to your cassette? CCEP's get used thousands of times but I've never heard that before.

The standards for hose length must be for a minimum length as all the hoses at chemical emptying points I have used recently have all been of a different length and different type of hose. Given that the fact that these hoses are usually put into the actual cassette you can understand the need for an anti syphon device! I think we are a bit curious as to how you damaged your cassette by using a Club emptying point?

I've just returned from Rosedale Abbey and the hose and reducer valve on the cdp was ridiculous. The hose was so long and water pressure so low that as soon as the flow hit resistance of going 'up hill' the reducer valve kicked in and you got wet feet. There was water all over the ground running through the area because of a slight slope. I think this is mainly because the existing taps will now be to low to allow the system to work effectively. It really needs sorting out. The reducer on the waste water tap didn't pose the same problem because it was of a short length. According to the warden their hands are tied as this is now a necessary requirement under new regs. The only way I can see it working is for each tap to be put at such a height that doesn't allow the rinse hose to bend. I dread to think what the ground will be like in frosty weather.
This system must has cost a fortune of our money to implement and even more money to put right the water loss.

No idea about the legal requirements but if you buy an outside tap they've to have a none return valve built in, not the silly 'nabic' things you only find on a CC site. The CL we used last week just had a standard tap on a post with no hose at all .... perhaps some legal requirements are more legally required than others

The 'anti syphon' valves recently fitted to CCEP taps on CMC sites are fine where water pressure is high, but where it is low, it is causing water to leak and spray everywhere. Meathop Fell is not known for high water pressure, that combined with large bore pipe.. means a trickle at best and wet feet and trousers from the anti syphon valve.
Definitely dont like the things, no different from a leaky pipe...same results anyway.
Water all over ground and toilet emptier.
Ice rink come winter.

Looking at the data sheets for this interrupters it says
" Reductions in diameter, angles and bends in
the connecting pipe on the discharge side
should be avoided."So not designed for a hosepipe on the outlet side.
"A straight section of pipe at least 10 x DN
should be allowed before and after the device
to allow conditioning of the flow."So even on a 15mm pipe that would be 150mm. The examples i have seen have been coupled directly to the tap!

From their website
PIPE INTERRUPTER
The NABIC .....incorporates ventilation ports that are totally unrestricted and permanent, water is guided past these air vents using a venturi type nozzle. Since they are constantly open to atmosphere this stops siphonage and allows the escape of water in the event of backflow.

thanks, often wondered what they were and why they were there.

Since the introduction of pipe interruptors to service points because of "some " water companies latest "regulations?"as we have noted on our numerous site visits, are not country wide and it is obviose that those that are fitted with them it is not now possible to wash down the ccep after use, it now needs the taps to be resited at a higher level to overcome the interruptor doing its job because of the need to "bend" the flexible pipe to rinse the cassettes and the ccep walls, and if also as noted on some sites ,when fitted to the fresh and waste taps it is also difficult to fill the fresh water and rinse the waste containers,

Just back from a week's stay at Meathop , where I had to advise a young woman NOT to empty the toilet cassette down the grey water drain /grid.
Are these people totally unaware of how things are done , do they not ask or even try to find out before using a caravan & a touring site regardless of it being a club site or independent.
I know we all had to start at some time , but If I don't understand anything I ask..... or YouTube it.

Would It not be a better solution to fit a non-return valve in the line, either before or after the tap. Then there could be no siphoning, any back pressure would be very low I cannot see how it could be generated in this situation. Also, in domestic kitchens new taps are now fitted with NRVs.

It is neither new or just some water companies, at least in England and Wales. It is a requirement within the "The Water Supply (Water Fittings) Regulations 1999". Plus way before that it is what we did anyway to avoid ever being hauled up on a negligence charge.
Here the issue is the fact there is a hose, so it could backflow up that.
I expect the introduction of an air break interrupt valve is simply because the "penny dropped" that a directly connected hose contravenes those regulations, and that is one solution.
A 5 van site, not one of ours, I used this past weekend had a plastic water butt, and a watering can. The owner here clearly was switched on, providing a compliant system that also worked well in rinsing out the cassette and the sump funnel.

It's probably part of a "cunning plan" to get us all on to fully serviced pitches including black waste. For an appropriate fee, of course.

The reason i posted"some" water companies is that on some cc sites the interuptor was not fitted? as it was easy to rinse the ccep and cassette without getting wet legs from the taps as happened on some sites although the tap was in the usual place

As Cunning as a Fox Who's Just Been Appointed Professor of Cunning at Oxford University?
while I would love to agree with you, I just don't see the club being that cunning?

It has still not been described how the £45 worth of damage came to be caused by the fairly weak flow of water.
