Will the siphon work if I extend the tube another 25 feet?

    Hi friends,

    I've had my very first fish tank (29 gal freshwater) for 2 months now and has been doing couple of PWCs where I had to carry the water bucket to dump the water into my front yard which is just 30 feet away. So that got me into wondering if anybody has tried to extend the siphon hose longer so that, like in my case, the water will go into the grass rather than a bucket next to the aquarium. That way I don't have to carry the water bucket at every water change time. Has anybody tried to do it this way and the siphon still works?

    I have a top fin gravel with an easy start up siphon ball.
    If the siphon will work with an extension hose, then I will definitely go and buy and extension vinyl tube.

    Thanks.

    i bought a 50ft python and it is great. you hook it up to the sink, and the pressure from the sink, sucks the water out. then flip the valve, and you refill it that way too.

    if you got more tubing, you'd need that extender thing, to hook the pieces together....then a hose clamp to seal it up. i dont' know though if it would leak or not. but it's worth a try....

    Provided the outlet is substantially lower than the input, then yes it will definetely work. YOu will need hose clamps and hose connectors fitted to the size of your hose.

    As long as your siphon is started with enough force, then it will easily utilize all the gravity possible and siphon successfully.

    I have a 25 foot tube connected to a pole outside by my garden... I use a submersible pump to pump the water out, and then reverse the pump to pumn water back in... very very quick and easy

    You can use one of these... http://www.gardena.com/int/water-management/hose-connectors/extension-joint/ to connect the hoses together, they are meant to be used with the quick couplers for garden hoses. It's what I use and they don't leak, but if you try to refill the tank just using them, the pressure of the water from the faucet may make them leak or pop out.... but I just use mine for draining.

    You get heavier duty ones that are meant for hoses... they will not leak. They are watertight, even at a really high pressure

    Yeah, I just don't require one other than for draining so pressure in my case isn't a problem and I just use a garden hose with a quick connect and shove the other end right onto my gravel vac hose, then if I want to use just the gravel vac to collect a little water in a bucket for my house plants I can easily pull it off and put on the suction bulb like the OP uses.

    I've extended mine with hose from Lowes hardware store. Bring in your gravel vacuum piece and match it up to tubing. Lowes sells it by the foot real cheap.

    Understand... but yeah i was just saying that there are heavier duty ones that arent really much more expensive, and havent failed me yet :)

    Hi, my design of extending the tube to 50 feet to reach my front garden worked perfectly! Now, I don't have to carry water buckets and dump them anymore. I just refill the water with bunch of 1 gallon milk bottles that I've saved.
