hi, was hoping someone could help, moving house and require ro system now, have big cellar at new place but could prob only fit small tank through door (like garden water butt at a push) might not even be able to get that in, i can park up right next to back door and kitchen sink is next to door, heard of someone on here having some ro solution using under sink, is this another solution?
any ideas are really appreciated, thanks in advance,
andy

Get another tap put in somewhere closer or run it how it`s supposed to be used under the sink only divert it so it goes into the storage tank.

get some 125L or 250l tanks and join them together then a transfer pump out to van, problem solved.

under the sink ro could be used but the production would be very slow unless you have a 45 inch cupboard min.

thanks guys, it all seems so complicated to get your head around setting it all up etc, is there an easy way to understand the process? website etc? as its hard to even take advice if you cant picture what parts needed and to do what if you know what i mean, thanks agai n

sounds complicated but really it is not, your welcome to call me 08877 732 789 either tomorrow or the tues

Matt has a diy forum, not sure if it is on there or not, but connecting tanks is very easy to do.

thanks very much ian, might just have to take you up on that!

[FREEMANSCLEANING]

under sink........poss a merlin ro..no need for storage tank as long as you have a good pressure from a tap you could fill your van tank/containers direct with a couple of hours polish of with di cylinder .....i have a 450ltr tank from empty will refill within 2 hours no storage needed

[andyatkinson]

that sounds good also, what do you mean when you say a couple of hours polish off?thanks

[matt]

the 250 L tanks are fair narrow ( but they cost 100 quid each )

you can get SLIM LINE rain water butts,

B&Q do them for about 30 quid ( from memory )

but they have them here for 20 quid each ( just so you can see what they look like )

http://waterbuttsdirect.co.uk/spacesaving.htm

100 L each, they are only 35 cm square (14 inches) wide

you can connect then together easy enough, personally i would just connect the taps together ( so run some pipe between them all ), water will allways find its own height, so if you have the taps open and then linked with hosepipe, they will all fill up at the same height

you could get 3 or 4 ( or more if you needed it ) and just buy a cheap sub pump ( something like 10 - 14 L per min , cost about 10 quid ) you could get a sub pump for each barrel and zip tie the hosepipe together and wire them all to the same point, it would take less than 10 mins to drain them rain water butts

i dont know how much water you use ( we will say less than 400 L )

4 X 100 L space saver butts 80 - 100 quid

4 X cheap sub pumps and hose pipes 80 quid

job done, your setup and ready to produce and use 400 L a day

of course if you now only use 300 L you can just do it for the 3 butts and pumps etc etc, you can allways add as you need it

[matt]

only downside to the merlin ro is the cost ( 300 quid ? ? ?  ) and you go though resin quicker

[andyatkinson]

thanks matt, best if i explain my set up, i will use no more on an average day than 250 litres, workin on my own for now and downs trad. I will be using the 125 litre omnitrolley from a trailer so prob comin home at lunchtime to fill up again, so need a quick solution there for refilling unless of course i carry 4 0r 5 25 litre containers.
Not even sure after what ive said is situation for water access in cellar, but is old house and i imagine i could make a hole in floor under sink for hose pipe (only floor boards).
Already have 1 250 lt upright tank and one 250 lt lay flat tank if these fit in on moving day they might be a head start otherwise the slimline garden butt solution
Thanks!!

the merlin idea with your 125 L omintrolley will not work that well, you will be better of use your idea in the cellar and a sub-pump

you can pump your RO unit under the sink and just run the 6mm pipe to the cellar ( as 6mm is really thin, you will either be able to just drill a 7mm hole though the floor, or look for a air-vent for the cellar outside and run the pipe outside and then into the cellar that way

failing that, you could just sit the upright 250 L tank just under your kitchen window ( outside ) and fill that , just box it in the put a planter on top and it will look nice

[andyatkinson]

funnily enough i was just thinkin that  (boxin it in makin it look nice!)
So assuming i went with that option, i have the tank already so i need (shopping list)
RO unit
sub pump
various bits of hose and connectors
inline tds?
i have 3 big DI vessels already.
Do RO units get sold on the basis of how much water its capable of producing a day? like i could get a slightly cheaper one as wont need more than 250 lt a day? and could always upgrade in future when usage and cash flow increases?
how much do you reckon for RO etc?
thanks again for help, im really gratefull

100 GPD fills my 210 L rain water butt in 24 hours

that would cost you just over 100 quid

100 GPD fills my 210 L rain water butt in 24 hours

that would cost you just over 100 quid

also if it has a problem it will cost you a day to refill. you can get a merlin for about £100 or less second hand or a 300/450 gpd I would not go for a 100 gpd as it will cost you more sooner or later,

why

he has 250 L upright tank to fill, what use would a 300 / 450 GPD unit be, so he could fill it in a few hours ? ? ? ? he will get by with a 24 hour refill, he has no reason to fill it in a few hours, he has said he uses 250 L a day and will have that 250 L tank to fill, he could have a few 25 L barrels ( or even a 100 L spacesaver rain water butt )  as a emergency stored in the cellar ( if he has a busy day )

if he does find he is running low at times, then it would be just as easy to have a
few space saver rain water butts in the cellar and they could be filled on the weekend

if the concern is that something goes wrong with the 100 GPD unit, then surely the same concern will be for the 300 / 450 GPD unit  ?? ? wouldnt it ? ? ?

he could buy a spare 100 GPD RO unit and still have money spare over the 300 / 450 GDP

a 300 GPD makes 1135 L ( so i guess real terms that would be 1000 L )

a 450 GPD makes 1703 L ( so anything over 1500 L )

he uses 250 L a day , so what does he do with the rest of it  ? ? ??

[andyatkinson]

thanks again both of you, i dont know enough about it to be certain myself but i did have same thought matt that i could fill over weekend and any days off to build up a supply of spare water, am also really interested in finding out about rain water butts as have roof gutter and extension gutter.
money is tight as moving, and first baby on way in 12 weeks so probably do have to go for the 1oo gpd option , but open to all of your suggestions, thanks both.

[andyatkinson]

i wrot that as you wrote your last post ian, much to ponder...
wasnt life cheaper with my squeegee!!
however i couldnt go back now, i love it,
have a good bank hol

Get a second hand unit m8, water butts are good cheap option to start with

Matt some where along the line you must have gone out if you use a 100gpd unit and there was little no water there for the days work.

To me it would cost me a damsight more in lost money then a new one, my thinking is this:
if you can produce more quick , it saves time, should there be a problem you can fix and fill quick, waiting 24 after fix would cost 2 days work, now doing the maths my end I would have lost quite a bi of money scrimping on what is the key to earning the money in the first place. if he dont have a back up tank which I would recommend if going for a small domestic water purifer then a 100 gpd ro would not (sry should not) be an option for anyone serious about there business.

Easy to say it may not happen but chances are with a unit not designed for use to this degree it will fail and it will cost this guy money, he can get a unit that can produce water quicker... You must see my point on this m8, I wasnt knocking what you was saying, but I do not think a 100 gpd ro is good enough for a window cleaning business, buy that cheap and you will buy more than twice costing more money..

in allmost 7 years i have not had enough water ONCE, i then phoned a local window cleaner and drove to his house a filled up some barrels
