hi i have about 300 regular domestic customers and not many comercial.i won't be loocking to do very big jobs at the moment just trying to extend on the comercial bit ,day nurseries ,schools ,3 storey houses for the start so that's why i was thinking to start with the trolley first and in the future maybe to upgrade to something bigger.also i'll do atrial for my existing customers to convice them why i'm changing ,to show them the benefits of wfp.thanks
Personally I would change the bulk of your work over to wfp as once you start this will be more than likely what you will do, you can get a van and a wfp system off ebay for a couple of grand, if you want to go after commercial then a back back imo will not be sustainable and will cost you in time.
but if you are set on getting a trolley it will depend on your wallet, you can either buy one around £500 or make one about £250 all in, but you will then need a means of making the water, that will depend on the tds of your water, where you live if you say I would be able to say either ro and di, or di only.
ro can be bought second hand if you want to test the water say a 300gpd and a di about £40
all in about around £700 maybe less if you can get good dals would get you set up with what you want,
your welcome to give me a call and have a chat, my numbers are on my home page.
