My main reservation about DIY would be about what happens to the tank in a crash.  Apart from the tank fitting, I could do the rest safely by DIY - though I would need to do a quick bit of research if I wanted to fit a split charge relay.

Bulk head? If not then just have a smaller tank laid flat

Its so easy. Strap a tank in, put pump on a board. Connect pipes. wire controller once you find some where to mount it. You don't have to put DI in van. Fill from garden hose, into top of tank

Exactly,

Although try to make it look a tad neater than Duncan's 

LMAO
NO it works perfect. If I need to remove it, its so easy. That picture was when I first installed it. I said I would make it better at a latter date......1 year later

Looks like a bomba gone off Duncan! The system is good, it's the land fill site in the rest of the van that's the problem!

Bulk head?

Are you seriously suggesting the bulk head would stop a tank full of 350ltrs or more of water in a crash at 40mph + if you are then you're nuts

Instead of getting crushed in one place at least you get crushes evenly lol.

[Smudger]

Has any of the 'professionals' done a crash test of a loose tank with van bulk head ?

Factory bulkheads are supposed to be shaped for maximum strength, but I don't know if they have any tests/ratings etc..  My theory is that the water although heavy and solid would deform and burst thr plastic tank before it had chance to totally demolish a bulkhead.

I have a 400 l upright tank strapped snug against bulk head.
I have added additional baffling - 80mm diameter perforated land drainage hose, 25 m cut to lengths and stuffed in vertically.
I consider it safe. In the event of heavy braking or a crash the water would need to gather forward momentum in order to breach the bulkhead. Drive sensibly, allow for braking distances.

As you can gather my system is diy.
With a basic di system as the op has mentioned I think diy is still the way to go.
The only thing a supplied system has going for it is sometimes its appearance, they can look tidy, but then is that important ? its not going to make you any more money, only cost you more.

[Matt.]

Am sticking with above, no way is the tank going through the bulk head, it would need forward movement.

Bulkhead behind seats is made to take impacts, no way would it burst through.

Yes I am about to change my tank from 350 with straps to 500 bolted, behind bulk head just touching it, this is nothing to do the fact I think it's not safe coz it is, I just want a shelf welding on either side, 1 for battery and other for Merlin, will have bracket under Merlin for di bottle, I am going to run a hose from Merlin along bulk head through 2 x salt bottles but will fill with resin so my main di bottle will only be used as back up and can easy change 2 small ones.
Am then looking to fit another tank ( eBay item  390534818207 ) above 500 facing out of side door and attach to roof using bolts and brackets, am looking for a small hose reel that I can use 50m pole hose for this tank to apply chemicals

I already have 1 hose reel attached to roof so will add another to make 2 man set up


Hopefully after all this is done around the top end of the van and very compact I can use the rear end of the van to sort my pressure washing venture.......but that's for another day, let's just get the wfp all set up perfect first.

I don't really think I would ever go and buy a new system at a cost of 2700 like says above 700 is plenty and I have seen Jakey boys setup a while back and it's propa tidy.

.............. Do you think Jakey boy might let me put my name on his system for 2k 😄👍

[duncan h]

My Transit bulkhead is solid. Really thick. It was till I removed it and strapped tank to seats lol. Only 250ltr. If a tank is up to a bulkhead without a gap, all should be ok

[slap bash]

Dont you fellas know if you don`t spend a fortune then you will be a crap windy with a system that will take you life at the first turn. We are a very developed industry with all the levels of snobbery. Some even speak in capital letters. And some are not spoken to at all due to them using dated methods or heavy poles. What is a professional system? Its one, putting the same parts as you can buy and telling you its better because it has a Designer sticker.

Of course, remember the tank is baffled, plus if it's a flat tank then of course it'll be safe, my bulk head is solid as a rock, thick solid metal, stop being a turd and go and work for health and safety. Drive safe allow for stopping distances, and all will be well.

Bulk heads are designed to embrace impact. A water tank will not go through a bulk head unless it had a lot of space to fly and smash through it. Even so it would only dent it. A flat tank would not have the force to even remotely bother a bulk head.

[cgh window cleaning]

Every body has different needs or reasons for choosing the system they have.

For me I wanted it to be as safe as possible and I hate d.i.y and I'm no good at it.

That's why I went for grippa there tanks and system are designed and manufactured by them and gardiners and crash tested as well as fitted by people who no what there doing.

With it being crash tested I have some idea and confidence in how it will preform in a crash.

Personally, I wouldn't want to rely on a bulkhead.  There is something that you don't seem to have considered.  Supposing you collide with another vehicle or run someone over.  The police would be all over you like a rash.  They could easily allege that you didn't break as hard as you would have if the tank had been fitted professionally.  They might just about be able to swing that in a courtroom too.  If death occurred, it could go as far as a manslaughter rap (worst case scenario admittedly).  So it's not just about whether the bulkhead would protect you.  It's also about whether you would hurt someone else by not applying the brakes as fully as possible.
Yes, we can all drive carefully.  I always have respect for any load I'm carrying.  But it only takes one idiot out there or even another good driver having a bad day...

"I looked at pure h2o systems before fitting my own, I just couldn't justify the money for what you get, it's cheap stuff mate"

Not pure h2o, never heard of them. Pure2o is where I got mine from ( www.pure2o.co.uk ) the value brand of ionics.

The safety aspect is another thing I didn't mention in my earlier post. Pure2o systems are crash tested, which was good for piece of mind.

There will always be people who want to build it themselves, and good luck to them. Just saying, that faff was definately not for me and I've never regretted getting a properly manufactured system.

[Mike #1]

Fitted mine for a lot less diy my God have I sworn , My set up is different to most as I have an Mitsubishi L200 with a 400ltr flat tank strapped in Load-bed with pump-box cost less than a grand with hose reel and fittings

Double bulkhead and their ain't an inch for the tank to move in any direction .

I really didn't want to get into the pro-fit v DIY but...

How would a crash tested system fare any differently to a DIY one in a collision for someone outside (ie not the driver or passenger)

Same weight on.
Same brakes.
Same reaction time.
Same breaking distance.
Same stopping distance.

Not a   post-a genuine question.
I've had both DIY & Pro-fit systems so no axe to grind either.

Wrong. Its works the other way round. Anything in the back of a closed can be left sat on its own. You are responsible to make it secure (strap down) A tank bolted to the floor can be considered fitted in correctly and weakened the van floor. The van floor isn't designed to have bolts drilled in it. It works both ways
