Gravity Fed Hot Water System Overflow

Gravity fed water systems.

Gravity fed hot water system overflow.

Using compressed air to blow out the pipes is a good way of doing it although you must be careful you don t blow fittings apart by using too high a psi. If you do have a gravity fed watering system in place you may need to clean out the pipes every so often to remove build ups of sediment like iron. Only low pressure gravity fed water systems can be pumped. In the feed and expansion tank there will be a float valve another name for ball valves which controls the flow of water into the tank.

If you have a hot water storage tank fitted just above the ceiling within the loft you will most likely going to get what is know as the normal gravity fed water pressure. As the water cools at the end of the loop where the last part of the loop is not insulated it is thermo siphoned back into the hot water heater dear tim. Gravity is a force which attracts all objects on the earth surface due to the attraction exerted by the planet s mass. These are fitted on the pipework to the tank and give a very primitive control over the temperature in the hot water cylinder.

These still the most common water systems in the uk. The give away signs that they are starting to fail include a lot of fluctuation in the temperate of the hot water and continuous discharge from the overflow normally out of a small pipe on the side of the house. I am not a big fan of cold showers. Gravity hot water recirculating system a gravity hot water system works because the heated water which is lighter rises through the loop.

It is this force which makes that all bodies or things always fall at the lowest point for example a mango which falls from a tree. When it comes to buying taps and showers you need to be aware of the pressure generated by your water system all taps and showers will work on different minimum pressures which should be stated by the retailer or manufacturer. A normal feed of water pressure will be between 2 to 3 meters of water pressure which is measured from the top of the water level to the outlet of the water which is about 1700mm below the ceiling to the bath standard home built today. Gravity control some systems have very basic hot water controls such as a thermostatic tap stat.

The flow rate you are currently getting from your water system combined with the number and type of installations you have in your property will determine what kind of pump you require. If hot water is coming out of the overflow pipe turn the system off wait for the water to cool right down and set the float valve to allow less water into the tank.
