Is this brodex system worth asking price.

Wow cheers spruce great info mate.
I pay 4p a litre from Courtney. I have a 350 tank so

0.4 x 350 = £14 per fill.

I cleaned 10 houses the other day via back pack all first cleans aswell

5 x fronts only = 2 bay windows and front door on each.

5 x full house cleans = 2 huge houses, 3 terraced 3 bedroom houses.

I used the 350 on this lot. So I'm not sure wit regular cleans how much less ill use. But if I'm averaging 1 full up per day then £56 a month on water. So 9 months tge systems bought itself on water alone. Let alone time saved.

How long do you think my filters, membrane and resin would last doing 350 litres a week.

If you are going to process water once a week then the r/o won't be working hard enough IMHO. It needs to work regularly to work efficiently. (This comment isn't from personal experience, its what I have picked up from what others have said. There maybe some who would say that there isn't a problem.) Hence the reason for saying that 1 day a week its probably better to buy in your water and write it off as a business expense. (Its not a tax free expense - its just that your expenses are taken away from your turnover so you don't pay tax on that amount.)

@doug atkinson visits this forum so maybe he could advise you better with regard to usage as he deals with a wide spectrum of cleaners. Tagging him will hopefully bring his attention to this. /emoticons/smile.png

Rather than buying a second hand unit, www.daqua.co.uk have a 4021 system on sale for £400 including VAT and delivery. You already have a 350 liter tank which is better for a day's work than a 250 liter tank. Into the future you will probably ditch the backpack in favour of a hose reel and pump. If you do then you will need more water.

Lets say you did 7.5 full houses as per your example. You used 46 liters a house. (I'm surprised it was that little tbh, but then we live on the North East coast so we use more water washing and rinsing due to the salt on the windows.) I would guess (assumption) that you would use about 1/2 that or even a little less on a maintenance clean every 6 weeks or so. That's roughly what my son uses when we work away from the direct influence of the sea.

I don't know your circumstances but I seem to remember somewhere you stated you weren't on a water meter. If your tap water is a high tds then your membranes may will not last as long as ours do. Again if the membrane is working at 98% efficiency then the remaining tds the resin is required to polish off will be higher. Eg. If your water is 300ppm then at 98% the tds will be 6ppm. So your resin will last a third of the time mine does.

If you live in a complex of flats then processing water could become an issue as most likely the complex is on a water meter. So this has to be considered as well. You could buy all this stuff and a little later the body corporate could ban you from filling up.

If you are in a hard water area then you will need to have a higher waste to pure ratio. It could even be as high as 3 waste to 1 pure.

The price you are currently paying at the moment a 4021 and di vessel with resin would be paid in 36 fills.

What I always say to customers is think ahead and not present. Bit like doing a business plan for the future.

Small R/O's will do the job if you have a static tank but you end up buying that then need more water as business grows.

4021 system will be sufficient for a 350 litre tank but as you progress you then will be looking for a 400/500 litre tank.

Hi doug

Thanks for reply. So would you say that the brodex system is not a good buy?

I will only do 1 day a week max. So will only filter maybe 350 a week. Will it work well of better off buying still?

How long would I expect my resin, filters and membrane to last. I'm in London don't know exact tds but would hint at 350_450.

The system itself will be a mornings work then to fill it up depending on pressure you will be looking at 2 hours so it is not efficient to do a days work. You could carry a couple of 25 litres drums filled which may help.

If the system is 3 years old you can tell from the date on the pump.

If he has changed the membrane ask to see the receipt, if he has the worth probably £500.

Brodex systems are going next to nothing, chap locally was selling two for £50 ea.

Had one customer turn up with one he found in the scrap yard.

The problem with the 250 is the position of the pump and pc board which are positioned wrongly. The pumps and boards always go on this model. The 500 ones are better.

The filter you would change every 10,000 litres and make sure it is a carbon. The membrane as he has just changed it has lasted him 2 years. Resin depending on input ppm you would change that around 4k+ litres.

It will do the job but what may find you will need to change it within a year.

Interesting about the pump and pc boards. Any 250 liter tank is too small for a days work IMHO. Even that 350 liter will stiffle any future growth, especially during the longer summer days when he needs to put a little in the kitty to weather the winter storms.

So in your experience Doug, would @Reach For The Glass find he wouldn't have an issue if he only used his r/o one day a week and it was 'standing' (full of water of course) for the other 6 days?

My old 450gpd has been standing for 3 years. I ran it the other day so I could refresh my memory of how slow it was. Believe it or not, the rejection rate on those old membranes was similar to what it was 3 years ago - 90%. So maybe an r/o standing isn't an issue.
