Hi folks, I'm a university student doing some research, hopefully some of you can help!

I'm simply intrested in the gardener's opinion of a pressurised water butt? The idea is that any collected water could easily be put under pressure, allowing use with a hose, much like the output from a garden tap.

How much pressure do you want? You get almost 1/2 psi per foot of
elevation for free. 1 or 2 psi is enough to deliver the water thru a
hose at low volume for flooding an area.

Don't forget about the possibility of using a booster pump if you want
to supply a sprinkler.

Pressurizing a large container that wasn't designed to hold pressure
usually doesn't work very well unless you can keep the pressure down to,
say, 5 psi.

Daft. Why would you go to the trouble for (at most) a few hundred litres of
water? Gravity feed is the simple solution for such a piffling amount.

Easily? How on earth are going to have a water butt that is filled from
some natural source (like roof runoff) that is at the same time presurised?
Oh I see it's not available to be filled and pressurised at the same time.
You switch modes when you want to use it. And this is going to hold
pressure and be simple and cheap? How will it be powered, hand cranked?

What about the excessive pressure if you don't use it much? You would need
an automatic pressure relief valve.

So next time you have visitors and they ask what is hissing in the garden
you reply "oh that is just the relief valve on my butt"

For me, gravity is free and does the job. No overhead, nothing to fix or
maintain in the plumbing. Firm believer in "if it ain't broke, don't fix
it".

If it looks like fish, smells like fish, its not
a cantaloupe.

It's a design project, so the whole thing is open to change. The idea was that pressure is only applied when you'd want to use it with a sprinkler or hose, it would be relieved for filling. And no, it wouldn't be hand cranked.

I appreciate that you may think it's daft; after all I'm on here asking for opinion, but theres no need for the cynicism...

So you will run electricity to it to power it? How do you seal off the
inlet when you want to pressurise it? A valve? Many such containers don't
have a lid that seals or any lid at all and often the downpipe from the roof
drops water into it from a height in a fairly rough and ready way.

This is starting to get complex and expensive for enough water for a few
tubs or a tiny roof garden.

Don't take it personally, it wasn't intended that way, I just lack control
when the possibility of a silly pun comes my way. I would think that a
design report that says an idea is not cost-effective is just as useful (or
more) than one that has to jump through hoops to make it work.

Hi, this is probably way too late for you, but seems as i've just joined i'll add my thoughts anyway!!! isn't there any reason why you couldn't pressurise a water butt in the same manner that you pressurise a fence sprayer? clearly the water butt would have to be fully sealed to allow for the pressure to remain locked in? just a thought.
