Title: Sealing Jerry Can when hose is inserted
Post by: corbijn on April 19, 2017, 02:59:29 PM
Hi There,

I have a Proquip Jerry can (http://www.proquip.com.au/products/water-cans.html (http://www.proquip.com.au/products/water-cans.html)) and we drop the hose from the drifta tap into it to get water out. I am wondering if anyone has created any kind of seal to go around the hose to stop debris blowing into the drinking water through the wider opening? I suppose I could just buy another lid and drill a hole through it? Any genius ideas?

Thanks in advance.

Find your self another lid / cap drill hole in it and fit a screw together through panel type brass or poly barb fitting to suit your hose size ... and a drop tube to the bottom of the container or a piece of PVC conduit   fitted with an over size washer  to cover the opening in the jerry .

Thanks EDZ - Sounds much more "sealed"!

Or you can find another lid, cut/drill a hole and insert a caravan manual sink pump in the lid.

A simple pump and you have water.

Holy crap.
A question with only good answers, gotta fix that.
The simple fix would be to turn the jerry can upside down, that way no additional sealing required, no holes being drilled and absolutely no debris could fall into the opening.
Just have to manage some way of stopping the water falling out.

If you do manage to make a seal for it, don't forget your breather hole, to let air back in.

Your breather would be a piece of bundy tubing, Like steel brake line, inside the spout and extending to within 50mm. of the bottom of the Jerry can.
The tubing inside the filler helps evacuate the air from the tank your pouring into and speeds the transfer of liquid from the Jerry can to the tank.
I have used similar devices in the past , for fuel as well as water.
Bigger the breather the quicker the transfer.

Or use a jiggle valve and hose to syphon from one to the other and wait considerably longer.

I'm talking about a breather that will let air back into the container that is being emptied. If no air can get back into the container (due to sealing the opening around the tube), to replace the volume of water that's coming out, you end up with a vacuum. Once the negative pressure is greater than the pump pressure, you get no flow of water. Unless of course you have a really strong pump, and you exceed the crush-ability index of the container...  ;D

Same principle on your boat fuel tank, and we all know what happens when you forget to open the tank breather... You spend the next 10 mins trying to work out why the engine stopped...

You OK, it might have been closer to 20 mins...  :-[

No need for extra breather tubes or snorkels,  just leave the cap 1 or 2  turns loose .   ;D

Thanks all for the great responses.

I think I will try turning it upside down ;)

The Jerry can has a breather hole already so that aspect is sorted, so now just to get a spare lid, drill it out then get the hose bits to build a seal. Where is the best place to the connectors and adaptors for hoses?

Cheers

Hey Edz, I don't think he's into single use and throw it away.
