Pumps to empty cylinders etc

[wrecked_24_7]

my friend gave me a pump that you attach to the end of your drill and where you attach a piece of hose to either end. Its supposed to suck water in through one end and churn it out the other. this one doesnt seem to work, not sure whether its just broken etc. But can anyone reccomend a specific one please. Its just after iv siphoned out a HW cylinder there is always a 3rd of water left in it. Please any help

When I syphon a cylinder I put a short length of 15m/m copper on the hose to reach the bottom of the cylinder, job done.

A short run of 15mm? How does that get all the water out, as the hose reaches to the bottom of the tank anyways? Just wondering thats all. Thanks for the advice

Not if it leaves 1/3 of the water in the cylinder.

As said if you have hose in correcty all water will syphon out
However when I have a problem with 1/3 of the water left in,I have rigged up a suction pump on the back of an old exercise bike,I found down the local dump,amazing how much hardly used exercise equiptment is down there
Anyway,have worked out if you cycle 4.3 miles on it,the cylinder will be empty,thats 6.9201792 km for you whiper snapers

Hi Dont go there. Get a bit of 15 mm copper pipe 200 mm longer than the depth of the cylinder, pull a 90 degree bend on one end. This with help as when you put it in th cylinder via the uppermost connection (hot draw off) the 90 degree bend may help the hose from kinking. Push the hose on the copper pipe and suck the other end. You can get clever and fill the hose with water first and then cap of the lower end. Once fitted to the copper pipe and lower end outside building remove plug. Good Luck

Ive got a wet vac , its become a very useful bit of kit that I dont know how i managed before without it, eg use it to suck out the annoying bit of water in the pipe that wont solder, drain down rads, empty the last 1" of water thats left in the wc cistern when you cvhange the syphon etc etc, you can get pond vacs that have a second hose on them to dump the water straight out to an outside drain, perfect for emptying cylinders in under 10 mins.

I use my wet vac on the end to get it started.

if the hose is lower than the bottom of the cylinder it sould remove it all your not trying to syphon into a pan on the same level?
