hi is the d-d reverse osmosis system any good as im looking at buying one,and i have read on here in a post which icant find eagle c said something about not letting the filters get dry so you have to use a ball valve and other stuff.. what do i need as in parts to set this up ball valve ect thanks bones
You can get the ball valve kits on ebay about ?20-25 pounds...just a small toilet cistern type thing...dont forget to get some shut off taps/valves and I recommend you get a TDS meter to monitor the filter either side - basically alerts you when to replace media. Best to get some extra length of pipe too I used 3 colours to easily trace waste/inlet and filtered RO.
I have a d-d and happy with it, just remember you wll waste at least 1:1 if not more...I use a water butt to catch the waste and recycle it for floor mopping/toilet flushing etc..as I am on water meters at home.
I have used a small roof tank to collect the RO ad use a small powerhead to pump it into 'caravan' water containers with drinking taps...I use these to top up the tank and slowly flow into buckets with the salt etc which ensures they are room temperature etc and easier to get up to temp with a small heater befoe adding to the tank.
hope that helps...always best to have ball valve anyway otherwise you will undoubtedly have mishaps and wet floors! I did and I know Eagle didtoo :)

The container normally stays connected and you have a pipe (stopped with a ball valve) and a sink top faucet (you don't have to fit the faucet but it allows you to use the RO to fill the kettle which stops it furring up). It will then fill a bucket from the reservoir in about 10 minutes.
I tuck by tank under the drainer with the RO unit and DI canister which uses most of the space.
i havent got the room to have the container inside. i will have to think about putting it outside in an insulated box or something, will i be able to use it with just a ball valve on the end till iget the tank sorted
yes, as it takes a long time to fill a container make sure the pipe is left long enough that you can put the container on the draining board or in the sink while it fills. That way if you forget it and it overflows you don't flood your kitchen.
