    Hi, newbie here.

    Just made a Harris pole, got a decent brush head, put two jets in and run a copper pipe along side. Will get photos when completed.

    Got an RO unit, a 1000l tank and a 350l tank for the car.

    Now, I have an issue, we are on metered water.

    How can I save money here? Water board say that we will have to go on a business tarrif and pay VAT on the whole lot. Someone on the web said they are legally obliged to put in another meter.

    We got a 5 stage RO plus a DI stage.

    We read my TDS and it is 157.

    Rain water off the roof, through the dirty gutters in an ancient water butt is 15 TDS. We are thinking of doing this.

    Is it viable to use rainwater?

    How long would straight DI last at 160 TDS and 15 TDS?

    Also, if I have used rain water and then stored the waste, could I put this back through as it would still be a low TDS?

    Cheers for this guys! Can't wait to get it sorted but it's being a tough journey!

    You don't need a ro for rainwater so there's no waste.

    You will also need some serious amount of storage if you're going 100% wfp.

    Yes though I've posted this somewhere before (cos am saddo) average 3 bed semi can harvest approx 85000 litres per year. But as I said you need to store it somewhere, do you have a swimming pool lol.

    If you cleaned/replaced the guttering and washed the roof that tds reading would drop through the floor.

    I'm no expert by the way but at 157 I think two di vessels might be better as theres no waste, Mark M and some other lads round here will be able to answer that one better though.

    OK cheers mate.

    Have got a pool as it happens, plus it's empty. :p

    May not go 100% pole at first but we might just!

    The RO unit we got a super bargain on and it's 200 GPD so if we did sell it we'd make money.

    Obviously just need to know what resin will cost etc and how long it will last. Obviously I think we probably will need an RO for the tap water when there is no rain.

    Cheers tho, will look at a huge tank.

    I'm doing similar but not really much wfp at all, have 1x200lt butt and store 300 in shed, luckily we've had a lot of rain so it's filling as I use it but think about having at least a 1000 lt ibc or something cos if it don't rain you'll run out quickly.

    Also 25lt resin vessel would only need changing every 9-10 months at 15 tds.

    The copper pipe is on standoffs and carries water up the pole. It's hard to explain without photos but works very well. Basically a copper pipe runs alongside the main bit of the pole. Attatched to this right at the top above the clamps is a coil hose. When extended the coil extends. The copper pipe keeps the coil away from your hands. It also has the advantage of being fixed at the bottom with a connector. There is also an ON/OFF flow switch and the pump has a pressure switch so will switch itself off.

    OK thanks.

    I'm thinking maybe get another one or two 1000l tanks and have one for waste, one for rain water and the one I have now for pure water.

    It's a hard one. Do I keep the RO for the draught seasons?

    I can't keep too many tanks as my mum is complaining at one! Haha. Will have to try and fence them in so it looks nicer.

    Rain water does seem an awesome way of doing it though, wouldn't even RO it, just a straight DI into the tank.
