Could someone enlighten a non technical person about what fittings i can get, that will enable a plastic garden water tank to be drained by connecting it (securely and non-leaking) to a 20 metre length of standard (1/2") garden hose please.
The simplest way would be to siphon it. Assuming the bottom is off the ground anyway. And the relative levels in the garden.
Get a short piece of hose with connectors all ready to attach it to the
20 metre hose. Fill the short piece of hose with water, one person holding it the other filling it from a can.When it runs out the bottom put your finger there and keep it tight. (which is why its harder to do this from a tap with the pressure)
Put the other end in the tank but near the top to start with. And position the end with your finger over it lower down on the outside. Water will run out of the tank down the hose which you can then connect to the longer hose.
The end of the longer hose would however need to be lower than the end in the tank at all times. But that could possibly be got round by filling an intermediate container.
Connect a hose to a tap, turn on. Put other end of hose in water barrel. When water comes out of hose, make sure it's immersed in barrel water and turn off tap. Disconnect hose from tap, the syphon is established.
Open the top, stick in hosepipe until it hits the bottom, pull up a little bit, place end of hosepipe lower than the base of your tank, shove hosepipe in your mouth and suck. Spit out shit and drain. Dead easy.
No, no, no. Thread length of wire through hose Use wire to pull string through hose. Tie Tampax to string. Insert Tampax end of hose in barrel Pull string, which pulls Tampax through hose, causing vacuum, liquid follows.
Easier still... place all of the pipe into the tank hanging on to both ends below the surface. When the bubbles stop, stopper the pipe ends with your thumbs. Draw out the discharge end and remove your thumbs when it is lower than that inside.....
Is it the sort of tank with a tap on the bottom? I found these far to soft to attach anything with no leaks. It ended up me using an old kitchen tp ap fitted and then you can use normal hose fittings. Brian
