Engine will not start

Two options:

1) Drain the tank - water will sink to the bottom. Disconnect the fuel line from the tank and drain it into a clean clear container. Once this clear container has set for 15 minutes, you will be able to see the fuel on the top and the water on the bottom. you can either :
a. siphon the fuel from the top layers back into your tank (after you reconnect the fuel line)
b. siphon the water from the bottom layer - put the remaining fuel back into the tank (after you reconnect the fuel line)

2) Add some "drying" agent to the tank. There is a product called HEET (there are others too - check at your auto parts store) - it contains methanol alcohol with some additives designed to absorb water. You could add this to your gas tank but make sure it is not more than 25% of the total volume.

Enjoy !

Clean waterrower tank

How did you get on with this?
I recently came back from a long holiday to find that I had a living water tank ( I normally have a curtain covering it, but it hadn't been covered properly ( or even at all).

In my case the growth looked like feathers in the tank...the rest of the water was clear.
The process I used was:
1: fully drain.
2: Flush
3: repeat until it is clean.
4: add a chlorine tab and schedule reminders on your phone.
To fully drain:
I siphoned the dirty water out using a Wilko home brew siphoning kit ( about £3) and the siphon pump that comes with the rower.
Specifically, I plugged the plastic pipe (hard) into the flexible tube by at least an inch, and CAREFULLY slide the pipe into the waterrower tank ( carefully: if the pipe comes out inside the tank, there is no getting it out).
Then I wrapped some clingfilm around the open end of the plastic tube ( to make a seal), and shoved that into the feed ( straight) leg of the siphon pump. It doesnt have to look pretty, just get a seal and be easy to remove. I could have used duck tape to make the seal, etc. Then check that the screw at the top of the siphon pump is closed, and the squeeze the bulb at the top of the pump to pull all of the water out of the tank and into a suitably sized container. I used a bucket, but you might need to use something lower, like a gardeners gravel tray, or lots of washing up bowls... depends where you keep your rower. Just have the storage ready.

The most efficient way of doing siphoning is to pump the dirty water into until it is over the height of the top of the hose, then smoothly remove the siphon pump leg, leaving just the hose to drain the dirty water into your bucket.
Back at the tank end, twist the tube so that you point the plastic pipe into the closest bottom edge of the tank, then use books to angle the tank so that it is the lowest part of the tank... gunk should fall into that corner, and your siphoning should then drain the most gunk out. I agitated the tank a little, to make sure I was getting the most muck out, it seemed to work quite well.
2: Flushing the tank.
Once the tank was as empty as I could get it, I used a fresh bucket of fresh water and filled the water rower tank - no need to remove the plastic pipe/tube arrangement from the tank at this point. Once it has at least 10 litres in the tank, you can carefully remove the pipe/ tube from the tank and spin the rower mechanism for a while: we're trying to agitate fresh water over the inside surfaces, to get the gunk into the water, rather than the surfaces. I found that it helps to stand the machine up, and carefully spin the mechanism a couple of times: it puts water over the upper surface of the tank.
Then it is back in with the tube/ pipe arrangement and drain as previously.
Then flush again with fresh water, then drain again.
At this point, my machine was clean enough to refill, add a chlorine tab ( free from the nice people at Waterrower) and job done.
The best advice.
Prevention really is better than cure: I recommend you use your phone to calendar a reminder to put a tab in every month/6 weeks or so during the summer, and every 2 months or so in winter ( UK, other countries sunlight/ temp may vary). In that way, you will never have to mess about with the siphoning kit again....

Hope it worked out for you!

Is there a check valve in the fuel system? when I shut off engine, gas runs back to tank, cranks a long time to get it back and start up, will almost drain battery after it sits for a week!

if its running back to tank after engine shuts off it souds like your fuel tank vent is clogged in your fuel cap...try loosening your cap and see if it quits siphoning back towards tank. you may have gotten dust or dirt in the tiny hole or holes in top of gas cap.

I have a puolan push mower that i put water in gas tank not knowing it was water , emptied it out put gas back in and it will not start . only when i try to prime it and pull cord will it start but shut...

If the fuel tank is higher than the carburettor and it has a float bowl, you could remove the bowl, empty it and allow the fuel to run out through the float valve until any water is gone. Any water should flow out first as it would be at the bottom of the tank.

Water flow problem

2 things it could be. Bad flapper seating or back siphon.
1) visually check the flapper. Is it worn, cracked, or not fully seating because the chain might be too long and preventing a good seating?
2) IF the flapper is good without anything blocking it open there, then you have back siphon. Make sure the small hose that goes from the fill valve into the over flow tube has an high arch. If the arch is too low, after the water is cut off the gravity will back siphon water out of the tank.

Need to siphon gas from gas tank of a John Deere

Go to the store and buy a siphon you would use for a kerosene heater.
You can get the fuel out with this item. When you fill it back up add some "Seafoam" fuel additive. It will help keeps it running better.
Good Day.

Starts just fine but then dies right away

Most likely Water in your fuel tank ... Look in the gas tank w a flashlight and water will sit at the bottom. looks like bubbles ! If so dump the fuel tank fully by turning the mower on it side. turn back over and let oil re settle... also check you fuel filler can for water !

2003 kawasaki ninja 250 stalls and bogs

Stalling is usually caused by water on the fuel tank. Drain the carburetor, better... clean it. Blow air on the jets and needles. Drain the main fuel tank and check for water residue (brown)... siphone the fuel back to the tank. assemble and install the carburator and you'll be off to a cleaner burn. Also, make sure that the spark plugs are cleaned.

Liquid bleach tank WM2277HS

Liquid bleach tank? Do you mean the small container one puts fabric conditioner into for the final rinse?

They have a siphonic action. In normal use you put a small amount of liquid into the tank and when the machine starts the final rinse, water is added. Once above a certain level the siphon starts and empties the tank into the machine.

Take the drawer out of the machine, put it in the sink and slowly run water into the tank and you'll see that the level rises to a point then the tank empties.

So, perhaps you are adding too much bleach (or whatever) and the liquid is siphoning out before you even close the drawer.

Or do I misunderstand your problem completely?
