    I'll let you know if I notice any niffyness :#
    In any case better a smelly butt than dead plants :D

    Good to experiment!

    I was umming and arghing over putting in some copper pipe for a more permanent install, but it's quite pricey to buy the bits and I only need it for a few months a year, so I'll just keep using the hose.
    Certainly going to continue to do this for the years ahead.

    I'd been considering putting something permanent up too but using plastic piping and leaving connectors to then attach / disconnect the hose to the bottom at ground level and a connection at the top near the bathroom window to attach the hose when needed.

    I'm glad to hear that people are designing ways to make grey water work for them.
  • Yeah, I looked at plastic too for a cheaper install. Just thought could make a neater job with copper.
    Also didn't look into the fittings to get to hose from plastic, did you find some?

    Copper, you can get 15mm compression to 3/4 male thread and whack a hoselock straight on it.

    Currently just chucking the hose on the garage roof. I tie wrapped it to the gutter and along a downpipe to my hose reel.
    I do have a bit much gathered hose, it reaches the pump with a but less.

    Does the hose run inside the gutter?
  • We have a car port to throw the pipe out beyond, which is a bit difficult each time. I ordered 10m of some inexpensive clear reinforced 10mm hose, which just arrived, so will give that a go over the weekend. A push fit reducer should come next week to allow the hosepipe and then hozelock fittings too. The hosepipe we have is 30m long - it's heavy duty and heavy and difficult (and dirty) to lug about and throw out.

    I see what you mean that a permanent fitting would look better for yours as well. 

    10mm rigid plastic pipe is available (1/2" probably too) and so are clips for wall mounting, I was thinking I could fit this down from the window, out along the wall and down again, then just connect the hose to it when needed since the difficult part is getting it down to ground level past the carport for me. There's loads of connectors on eBay, screw fit to barbed push fit and barbed push fit reducers. Some were metric to imperial as well and standard British pipe sizes so they should take hoselock connectors and providing they don't have a one way valve in them then I figured they should work in the opposite direction they were probably designed for too. Whether a hosepipe would fit into a screw fit connection designed for the rigid pipe I'm not sure, I didn't look into that part - but would depend on the thickness of the hose (internal and external diameters being the same as the rigid pipe) because I think they have to go inside the connector - but a barbed push fit of the right size to connect a pipe and a hose or a pipe to a hozelock screw fit, like you'd have on a tap, should work. There's quite a few things available once you start looking into irrigation fittings. A three-way or two-way connector with a valve (tap) would also allow me to syphon to either the front or the back gardens and just connect the hose outdoors at ground level to whichever is needed.

    It's certainly easiest if you can leave the arrangements up - perhaps for six months over the summer. Mine is permanent and the loop of hose lives on a hook outside the bathroom window. But I happily have the architecture for it, with a handy metal soil pipe right out the window and the window by the bath. The green hose then runs behind wood stores in the side return, so you can't really see it until it turns up in the garden. The hose is not a beautifying permanent element of the garden. but it's not too hard to hide it in the shrubs.

    To water the whole of the small garden, I could add a connector and add another section of hose. Right now I can reach most of it, which works ok. It's nice to have it 'out of the way' and pretty hidden.

    Sometimes I leave the hose end under a plant like a clematis. Then I just need to use the siphon to get the flow going and leave the plant to be watered without having to go outside. I move the hose around during the week so thirsty plants get a bathload each. I have well (oddly) drained soil  so I could leave the hose under any plant and give it week's worth  of bathwater and none would bat an eyelid.

    I can water pots too, but to do that I have to set the siphon going and the run downstairs. The passive way is easier.
  • These type of connectors could work for plastic pipe and hoses, they come in different sizes:


    Yeah when you think it could be used for half the year it does make it feel more worthwhile.

    Inside, but along the top. Drilled a few tiny holes and tie wrapped it
