hi Guy's
Under my last post (just put a Tank into my Trailer) Neil100 came up with a post asking me how I have vented my Tank?

I took the lid off the tank to have a look and there is no vent in it, not even a tiny hole, and no pressure release valve

Apart from unscrewing the lid slightly to allow air in, is there any other way of venting the tank, I know I could drill a small hole in the lid, but was wondering if anyone had any good ideas?

Thanks Guy's

Hi Jeff,

I would of shown you a pic of my sons Tank lid but hes out with his girlfreind somewhere, so I cannot at the momment take a photo of it, but if he comes home soon I will duly oblige and snap the inside and outside to show you.

On my own 800ltr tank, Facelift put 4 tiny holes in the top of the screw cap, They are not big holes, Tiny, I would guess they did them with a pin because they are that small. The problem being that when I have my tank completly full, water can drip out of the top, which means I have to put a scrim over it for half an hour till the water level drops. Not to big a problem as my tank stands quite high, and I only fill it up to the top if my son works with me from my van.

I did not want to use the same method on His tank lid as its a 400 ltr low flat tank which would cause it to leak constantly when filled over half full.

I therefore drilled a piolt hole at the highest point on the tank lid, Then I widened the hole with a slightly bigger drill bit. I then pushed one of these plastic pipe inserts that you have to use with the plastic tubeing with the John guest type of fittings.

I put a drop of silicone around the Plastic Insert and pushed it through the lid, Its a very tight fit. I then fitted a length of about 12cm of some 6mm ID tubeing that I fit on my poles, the clear reinforced type. I used an O clamp to fix it to the pipe insert, Just to prevent the insert from ever falling into the tank.

I inserted a  T connector into the  Breather tube to prevent any dirt from entering the tank. The Lid does not leak at all and the breather Tube allows air to escape from the tank preventing the vacuum effect.

Hope that explains it well enough jeff.

thats what i would do

you can get threaded tank fittings that haeva  thread on 1 end and on the other 6mm push fit, just fit that and have a bit of pipe long enough to go above the hightest tank point

job done

Many Thanks Nel and for pointing it out in the first place, I would love to see a picture when and if you get a chance over the next couple of day's.

I really can't make out, why the manufactures don't automatically fit a pressure relief valve, I checked my backpack to see how it was designed and they are so simple if you had the right fittings or knew were we could get them.

I know if I go down the route of just unscrewing the lid to let the pressure out, I'll forget to screw it back up again :
Thanks again Nel

I have a couple of fittings that might do the Job, off an old sureflow pump, were they screwed  into the pump.

Jeff,here`s an idea im going to try it myself,fit a small flip lid/cap at the top then all you need to do is flip it open when needed,something like this

or one off a shampoo bottle or even a small one off a fairy liquid bottle,

Many thanks nel, So simple but affective, I did answer your first picture post, and I do like the idea, so this weekend I'll do the same.
I already have all the parts in the workshop.
Many thanks nel you have been a great help.
Kind regards.

Took Your advice Nel  the piece I fitted was salvaged  from an old Karcher carpet cleaner, I used a cone cutter to drill the hole, I made it just big enough to start the thread and because the hole is like a v shape it sealed it very good, but I put some upvc glue just to be sure.
I put mine below the handle level, so that it sits below the insulation on my tank.

That looks nice and neat Jeff
