Best Answer

Its a simple vertical outlet pipe inside the cistern covered partly by a 'bell' which has an inch or so gap at the base. As the water level rises eventually the vacuum inside the bell is compromised, the water enters the bell and flows up and over into the outlet pipe and starts a siphon which empties the water in the tank until the level reaches the bottom of the bell and the siphon is ceased. The tank slowly refills and the process is repeated. The time between flushes depends on the incoming water flow rate.

How do you flush the radiator on a 2000 Honda Civic?

What I do is flush the system; 'cause if your rad has corrosion, so does the rest of the cooling system. Purchase a PRESTONE flush kit at a auto store along with a container of flush and at least a gallon of antifreeze. There are detailed directions on the package. Briefly, you will be installing a flush tee in the return hose to the heater core, adding a can of flush to the rad,running the car at idle and then attaching your garden hose to do the work. Very effective.


How do you flush coolant on a 1997 Ford Ranger?

I would suggest you obtain a PRESTONE flush and fill kit at a auto store. There is detailed directions on the package. Also pick-up a can of flush and a gallon or two of antifreeze. You will be inserting a fitting into the return hose from your heater core and hooking up a garden hose. After the flush is run thru the rad the garden hose does the work. Does a good job.

Yes; a special flapper that controls how much water is let out of the tank on each flush. Sold at better hardware stores.


What should you do about a dripping toilet overflow pipe?

Sounds like the float valve,or ball cock, is either leaking or is partially submerged. If it is an older plastic ball on the end of a brass rod,lift the cistern cover and bend the brass rod down to make the ball valve close at a lower level of water. If this does not work flush the toilet and manually lift the ball valve to the closed position. If it leaks then you need to replace the valve seal. If you have a more modern cistern with twin flush and plastic components,there is a level setting device located beneath the the water line to set the level. Click it up or down one notch at a time to find the right setting.
