can i fill it up from customers taps as i need it?
because i only need it for a few jobs, im trad in all aspects and will continue to be until i get enough 3 story work to finance a wfp trolley.
i mean on some houses there is one window on from at 3rd story and on back 2 velux on 3rd story.
what this about the tank. where do you store it
can i not get a resin filter thing on the trolley?
Alex.
We live in a hard water area. It would be possible to use a trolley with a resin container on it (I do actually have one of those) but it would work out very expensive with resin. To give you an idea, the TDS (impurity level) of water around our way is about 200 - 250 parts per million. Basically this means that a 25 kilo bag of resin (costing maybe £70 with VAT and postage) could have about 2,000 litres of tap water through it before it expires. Bearing in mind the fact that my trolley only has a 1 litre resin container attached, if I were using tap water in the trolley, I would have to mess around changing the resin quite frequently (every 2,000/25 litres = 80 litres). So changing the resin every 80 litres would be about every 1 and a half trolley loads. Personally, I feel that although this is quite possible, it would be impractical.
I only have a resin container on my trolley because my water purity (after the RO) was anything up to about 15 TDS at one time so I wanted the resin on board to polish it off. These days, I have a refillable resin container attached to the RO so I produce pure water into the tank - making the resin container on the trolley mostly redundant.
Water usage on the first cleans is usually very high. It needs to be in order to give yourself a reasonable chance of doing a decent job. With higher water usage, obviously the resin usage goes up.
If it's only the odd window here and there that you need to do, then using tap water in a trolley with a resin vessel could work.
Another option could be to get pure water from someone who already has some. If you only need a bit once in a while, you could get yourself some containers and I could give you some. If you store it for more than a week or so though, be aware that it should be stored at somewhere under 20 degrees C due to legionella forming.
Although a trolley can be heavy to lift, I just use a board as a ramp - much easier !!
Another alternative for the first cleans :- It's definitely easier with a van mount due to water usage. I could do the third storey bits for you meaning that you would need to only follow up with the easier, less water intensive cleans afterwards so that your water would last a lot longer.
The trolley I have is called the Omnitrolley "Classic" with DI - see:-
http://www.omnipole.com/omnitrolley2002300dpi.jpgThe one I have has a 1 litre DI vessel seated just above the handle. The handle is detachable if you need more room. It has served me well but I wouldn't use it to "make" pure water though due to the hardness of water in our area. I just fill it with purified water (no more than 004 TDS) and use it on the odd job as needed.
Alternatively, there is this one:-
http://www.omnipole.com/Omnitrolley_files/New%2050%20Trolley.jpgI did try one of these briefly at the seller's yard. It is cheaper than the "Classic" and, it has a 30 metre hosereel on it which can be VERY useful. It has no DI on it but if you were filling with purified water that wouldn't matter anyway. The only reason I didn't buy was my bank balance.
They are both Omnipole trolleys. They are the only ones I've used. You may find that there is a trolley more suitable for your needs but I am only able to tell you about the ones I've tried myself.
You can get an Omnipole trolley which is a bit cheaper and rely on getting your pure water from someone (bearing in mind that I might not always be available when you need water), or you can stick a DI on the trolley meaning frequent resin changes and purchases, or you can pay rather more for your trolley and get an RO with it to produce your own pure water such as with the Freedom trolley (never tried that one but others seem to recommend it highly).
Also, I don't think it's a good idea to rely on customers' external taps anyway. You can't rely on them - especially in Winter when many people isolate them to avoid freeze ups.
