I`ve had this set up over a year now,,filters,housings and bits from Gaps Water,better give June a plug,she really was most helpful. The hf5 membrane i got from Ionics and i think they remain by far the cheapest due to bulk purchases etc.
Anyway,its running right now and the input pressure,normally about 50 psi is down to 38 today. Its been going about an hour and tds in or out hasn`t changed and nor has the 38 psi,well alright its now 39 psi.
287 tds in, 005 out. I will admit to not checking as often as i should so i just checked the tds of what was in the storage 1000 ibc and the 500litre tank i have in tandem and thats 005 fluctuating to 004 and they are both looking a bit green and slimy inside now with a strange collection of debris on the bottom of both as they are outside and i am always leaving the lids off.
So of course i am well happy and have bothered posting because of the low psi this is performing at and thought it might be useful current info for anyone trying to make up their mind on an RO.
In case of a winter freeze,the RO set up is mounted on marine ply and portable so as last year(when i didn`t have any storage),it comes in on a night after i have used it to refill directly into the van tank.The van will have an oil filled radiator on a frost setting and a 3KW immersion kicking in at 5.30 am whilst about 9.30 to 10 am.Total electric cost per day is no more than £3.00 and i can live with that even when the van sits outside full of warm water all day due to me finding an excuse not to go out! I`m actually thinking i should spend the reserve fund i have set aside or its going to make it far too easy to stay at home.Though like most things there is a balance to be struck and i generally get there.
