Recycle Rain Water

There is a process that has become very popular since we have become more environmentally aware. This is the process of rainwater capture and recycling. The piece of kit that does it is quite simple and is called a water butt. The butt is fitted outside the property and quite simply catches the rain. The butt or tank is made from polyethylene and comes in a range of capacities. These butts are supplied complete with instructions and all the kit you will require and the setting up is quite straightforward, just follow the makers instructions.Tools:Tape measure, Hole cutter and a drill.Note:Square down pipes are simple to measure but for round pipes you will need calipers or string and a ruler. Pull the string around the pipe and mark the two ends meet. Measure and note this distance. Divide the measurement by 3.14 (PI). An Eltham Plumber can make this calculation. This is the external diameter. Fitting:A). The best way to fit a water butt is firstly select the downpipe to connect to. The pipe should be marked at the same level as the top of the butt, then, cut 3cms lower so that the rain diverter hose can be connected to the butt and remove the bottom half of pipe. Drill another hole for a tap at the bottom. This is usually pre-marked.B). Once the butt is connected to the diverter, reconnect the piece of downpipe that you cut off. This will then look like a tee section with the pipe running down and the diverter running into the butt. Eltham Plumbers can fit water butts.Handy to Know:There are stands available for water butts and also you can purchase a water butt pump that will give more flexibility when using the water such as in the garden.

Plumbing Valves

The term valve refers to a piece of equipment that will allow a liquid to flow through it but also close to stop the flow also, in other words it is a liquid flow controller. They are of various designs from simple to quite complex.Below is a small example of the names and also their function:The Globe: This valve incorporates a shaft in which something called a stopper will sit. The stopper will move up or down allowing the water to flow through. This valve is employed in situations where flow adjustment is required. An Eltham Plumber fits and maintains these type of valves.The Butterfly: The butterfly valve is fitted with a disc fitted inside. The disc will be the same diameter as the pipe in which it sits. The disc is also attached to a lever to operate, again to adjust flow.The Gate:The gate is employed in straight flowing systems. It has the second name of the sluice valve. The valve operates by a wheel driven wedge in side the shaft to control flow. Eltham Plumbers are experienced tradesmen.The (main) Stop: The stop valve is probably the ideal type of valve to fit in a fluid system that is going to require a great deal of water pressure and is normally the valve that is fitted to a domestic mains supply to isolate the water from entering the home and is usually fitted somewhere in front of a residential property for ease of access in emergency and maintenance situations.The TRV:The thermostatic radiator valve gives the homeowner control of the water that is flowing through their radiators by the use of a thermostat which is internally fitted in its body. The water heat will dictate the action of the valve and can be set by the homeowner. This is an ideal way of controlling seperate rooms and their uses. This saves wasting heat and money.

New Waste Fitting

The overflow for these types of appliance is already featured so there is no requirement to make a provision for this. Eltham Plumbers can install all types of appliances. Below is a brief guide to fitting a waste outlet for a basin, with the old one already removed.A new waste fitting should be fitted into the basin with the correct rubber washers, however if you dont have them, this joint can be completed by following the guide below:1). Place a ring made of plumbers mate or silicone rubber to the underneath of the part of the waste fitting that is fitted in the basin outlet. The appliance needs to be dry for the best result otherwise any jointing compounds that you use used will not adhere to the porcelain. 2). Position the waste fitting and place a second ring of plumbers mate, silicon or a large rubber washer around the threaded area that is visible at the hole in the appliance. Now fit a 32mm polythene washer.Lastly:Fit a large back nut on the fitting, which will compress and seal the fitting. Make sure the fitting doesnt turn when tightening the back nut by putting two screwdrivers through the slots in the fitting to hold it still. An Eltham Plumber can fit basin waste fittings.When the appliance complete you can carry out something called the: Second FixThis fix makes sure that the appliance is level, fixed securely, and supported, and all fixtures are reconnected correctly. Dont worry about the slope for the waste as it is set in the design of the basin.


The function of the isolation valve or isolator is really quite straightforward in its role. Should your kitchen tap develop a constant drip, the isolating valve allows you to just isolate the tap locally rather than having to completely isolate the whole house supply. A very handy bit of kit.The Valve:The valve itself houses a ball bearing, having a hole drilled through it. As the valve is operated, the ball bearing inside turns in line with the pipe, and allows the water to flow through. Turning the valve off has the opposite action of blocking the pipe, so stopping the water from flowing. The isolator requires very low maintenance and has only one internal part. 1). It can be operated with the use of a screwdriver that fits in a slot in the valve itself and can turn the internal bearing on (in line with the pipe) or off (90 to the pipe). Eltham Plumbers can fit isolating valves for any equipment.2). It can also be operated with a lever, and assumes the name of lever valve. The lever makes operation much easier. This lever valve is known as a full bore lever valve as it has a hole drilled in the internal ball bearing that is the same diameter as the pipework. These valves can be fitted in showers where a strong and uninhibited water is needed, and are also supplied in compression and push-fit styles mostly made plastic. An Eltham Plumber is trained to work with valves. Note:If a plastic version is used, this will normally result in the groove that is normally for a screwdriver operation being refitted with a small handle, as the groove is prone to being chewed with the constant use of the screwdriver for adjustment and the soft nature of the plastic. It is usually a good idea to avoid these types.

Bend Pipework

Sometimes pipework in your system needs to be bent in order to fit certain uses. A straightforward way to make bends in copper tubing is to use a specialist tool, called a pipe bender. These bending tools are made for different sizes of pipework:Small – 8/10 and 12mm pipes.Large ? 15 and 22mm pipes.There are pipes that are larger and would be very difficult to bend using a regular bending tool, so there would be a requirement to either, buy or hire a bigger powered bending tool, or dont bother and for copper pipework larger than 22mm diameter use fittings. Eltham Plumbers use pipe-bending tools.Bending Microbore: Smaller bending tools can be used to make bends in the very small microbore copper tubing. Microbore: This tubing is supplied in roles and is easy to hand bend. It is a pipe, normally 8-10mm in diameter and is used regularly in central heating systems having the main advantage of very low heat loss. It is also really flexible to run. But with this type of tube, to achieve a sharper, cleaner bend it is best to use a bending tool. An Eltham Plumber is experienced in pie bending techniques.To Bend:A). Open up the bender fully so its arms are 180 to each other. Place the copper tube between the arms and make sure it goes under the retaining arm and into the correct channel size. Bend the top parallel with the pipe in the grooves that are now enclosed. B). Pull the top arm down to begin the bend. Pull the arms together in one continuous movement until the correct angle is achieved. Open up the arms to release the bent tube and now remove from the tool.Note: A bender for copper pipe i.e. 15-22mm is available.

Airlock (Bleeding)

There may come a time when your radiators have become air-locked. If so, the guide below explains how you can remove the air and increase the efficiency of your radiators by bleeding. NOTE:Every domestic radiator has a bleed valve fitted. They are normally sited on the top corner of the radiator, either left or right side. This is a recess with a square metal block sat in the centre. This is made so that a bleed key can fit over it and then can be opened or closed. This key is small and has the correct sized and shaped recess to accommodate the square block. Eltham Plumbers carry all types of bleed keys.If you do not hold a bleed key, they can be bought from most plumbing retailers.Method: 1). Isolate the boiler and check the circulating pump is also turned off. These pumps often have direct live feeds.2). Place the bleed key on the block and turn very slowly anticlockwise for only a quarter of one turn. This should be enough to begin allowing the air to vent. You should hear the air begin to hiss as it leaves the radiator.3). Ensure the radiator bleed key stays on the block so as the air stops there should a slight dribble at which point you turn the valve (or block) off. An Eltham Plumber will carry out this job if you are not confident and will also guarantee the work. Check: If no water appears as you bleed the radiator, make sure that the feed and expansion tank in the loft is not still full. If so, the valve probably has a blockage. 1). Close the radiators inlet and outlet valves fitted on both bottom corners, and take out the screw from the centre of the bleed valve. 2). Using some small gauge wire, clear the blockage, and then open up one of the radiator valves slightly to produce some water from the valve.3). Close the radiator valve and refit the bleed valve screw. Open both radiator valves and re-test Also check for any leaks.
