coke bottle thread adaptor
I'd like to experiment with using a 2L coke bottle as a pressure vessel but
I haven't worked out how best to make a leakproof plumbed connection to the bottle. Does anyone know of an adaptor that would let me connect some flexible pipe (10mm ID say) to the neck of the bottle? The thread seems to be common for lots of bottles now but I haven't found a suitable adaptor yet. Tim |

I'd prefer a readymolded device if such a thing exists. A bit like this. http://www.amazon.com/Soda-Carbonato.../dp/B003V5EY44 A bolt in tyre valve would fit but then I'd have to find a way of making a water-tight seal to the tyre valve. Ideally I'd want something that I can just push a tube onto and secure with a jubilee clip. Tim |

I want it to act as a pressure reservoir to prevent rapid pump cycling in a motorhome pumped water system. Have a look here - a range of horsetails and adapters. http://www.gspen.co.uk/hose-adaptors-connectors.html I would use a 1/4" BSP tail through the cap. A reducer or back nut on the inside to secure it and appropriate reducers/tails to connect to your existing. -- €¢DarWin| _/ _/ |

I want it to act as a pressure reservoir to prevent rapid pump cycling in a motorhome pumped water system. The exisiting system uses a pressure switch which was okay with the old pump but a new uprated pump is causing problems and the recommended solution it to fit a pressure accumulator Of course I could just spend lots of dosh and buy the recommended one but it's more fun to try and do it on the cheap. ;-) http://www.ebay.co.uk/itm/SHURFLO-Ac...item27d2223cd7 Firstly, a 2 litre pop bottle is pretty flimsy, whilst it will handle the couple of bar pressure in a motorhomes water system, can it handle the vibrations and movement from driving down the road... basically if it fails, you will pump the contents of the water tank into the living area, secondly, the 'proper' accumulator has a diaphragm inside it, water on one side, air on the other, it's the compressible air the other side of the diaphragm that acts as the buffer, Last one i bought for the cold side of the water system in my motorhome was fiamma branded, and cost me about £14, looked similar to the one you showed, but blue, Problem with that one you linked to, they have mentioned 'boat' in the listing, and as soon as you try and sell something to the boaty types you double or tripple the price, and get away with it, motorhome part prices are expensive enough, but boat parts... whilst often the exact same thing, are just a **** take. When i fitted the eberspacher based central heating and hot water tank, i fitted a 7 litre hot water accumulator to the hot pipework (the 20 litre calorifier needed it to stop the hot water being pushed back down the cold pipework when the tank was heated) The 7 litre expansion vessle was only 20 quid, Not sure where you live, but have you heard of places like magnums, O'leary's etc, they are based in grimsby and hull, but there are a couple of similar places down south... cant remember the names now... franks caravans is one i'm sure, they sell motorhome parts at more realistic prices, and sell the stuff for home builders of motorhomes, and they also buy up last seasons stock from manufacturers when they change things in their builds, so you can get things a lot cheaper from them. |

Scratch them and you'll be in trouble but as long as the hose connector isn't rigidly fixed to the van so it can vibrate with the bottle it'll probably survive quite a lot. The lid will probably fail before the bottle. Last one i bought for the cold side of the water system in my motorhome was fiamma branded, and cost me about £14, looked similar to the one you showed, but blue, OTOH for 14 quid I might well go with the proper solution :-) |

They are incredibly strong. Yes, they can get pierced but that's easy to prevent. secondly, the 'proper' accumulator has a diaphragm inside it, water on one side, air on the other, it's the compressible air the other side of the diaphragm that acts as the buffer, I guess that the diaphragm stops the loss of the air cushion caused by the air getting dissolved in the water but it would be easy to "recharge" periodically.

Hardly rocket science to drill through the cap and mount up a gas tight fitment to one. Indeed - one bottle with a hole drilled through the cap and a car tyre valve pulled into it, full of compressed air; connected by a double ended car pump hose to another bottle with a valve in the base, full of water and a hose connected to the cap end; with a valve on the end of the hose makes a very good water pistol, with excellent range and continuous flow. Not that I'm admitting to taking such devices to Run To The Sun many moons ago! SteveW |

TBH if you must use a pop bottle, try to get hold of a 1.5 litre reuseable bottle from Germany, they use the deposit system and re-use the plastic bottles many times over there, thus the bottles are much much thicker than the flimsy disposable ones we get over here....i still get reminded of the time i braked hard after taking my mum shopping in her fiat panda, a bottle of pop rolled forwards and hit the rear seat runner, which are stupidly exposed in that car, 'ppppppiiiiiiiissssssssssshhhhhhhhhhhh' went the contents all over the boot. |

Since I mentioned a commercial product which is on widespread sale I must assume that there is relatively little likelihood of injury. Perhaps one should consider that a party balloon is an air reservoir and is prone to rupture, especially in aid of fun using a pin. Or, for that matter, a paper bag. For Millennials, it used to be fun to inflate a brown paper bag by blowing through the opening, close off the opening with one hand, and then hit the bag with the other hand. Bang! Any injuries were generally self inflicted by using too much force. Nothing to do with dangerous compressed air. Ah, well.
