Re-using grey water with a hose and a siphon - bath system.

    I was doing the maths  today of how much bath water I have re-used over eight years and it's somewhere around 25 000 litres. It doesn't have to be reprocessed by companies and has a second life and helps my roses grow. Though it may feel like a drop in the ocean it does count for something.

    Our bath is lower than the flowerbeds unfortunately. I did traipse dripping buckets through the house and filled the water butt, but I'm loathe to keep doing that. 😥

    Would this method fall foul of the hosepipe been? I know it shouldn't but I don't know how the rules are written

    I think it might depend on the region. It's not turning up much, as far as I can see.

    This week the Guardian and Telegraph recommended siphoning, if that makes any odds.

    I have my hose pipe hooked up. Not using a pump, I can get the siphon started by running the tap through it briefly.

    I wouldn't worry about whether this technically falls foul of the hosepipe ban. Nobody is going to arrest you for reusing bathwater.

    I agree.

    You can also slightly suck on the pipe out flow to get the flow physics moving in the pipe.

    Grey water not, perhaps, great growing items you might eat as the water contains pathogens.

    I need to put the plug in and save the shower water, then use it for the garden. 
    Something to setup this weekend!

    We did this in the 70’s.

    We'd been talking about doing this over the last few days then read this post today. We've been taking the water downstairs in buckets from the bath lately then pouring into a watering can but very heavy and very time consuming. I've got the same syphon in the picture for using with the fish tank, but i cover the open end while pumping the bulb to get the flow started. Carrying all that water down recently had made me think why we just don't use more grey water or have something built into (maybe newer) houses because even without a hosepipe ban we're still on a water meter and so pay for whatever is used.

    But it did occur to me that a tap / valve fitted to the garden end of a pipe attached to the wall out of the window would allow you to fill buckets / watering cans to then carry to wherever needed even if the pipe from the bath just went straight down from the bathroom window and stopped there instead of running the length of a garden. The buckets down the stairs was much more of a struggle than using the can to water for us.
