Water System

Stored System:
The stored system is the lower pressure of the two systems that are commonly employed throughout the domestic plumbing systems.

The system makes use of the cold water mains supply to a property to fill up a big water storage tank that is fitted in the loft space. Feltham Plumbers know all systems. The water that is supplied to the taps is from the storage tank, which means that if you turn off the mains cold water it does not instantly stop water flow from the taps. Should the tank be really large, then, it can take around a half hour 20-30 to empty and for the taps to stop running. In an emergency situation it can be a very long 30 minutes, so if your property uses stored water you need to know where the valves are that will turn this water off at once.

Mains Supplied System:
This is a high pressure system, as all cold water is fed directly from the main domestic supply, this means that by turning off the main cold water stop tap will stop the cold water taps running. The water is used in a unique way that controls the hot water with its pressure, pushing hot water out from the taps. The result is that turning off this mains will stop the hot water also. You could have a cylinder where the hot water is stored but with no cold water pressure to push hot water through, it wont reach the taps and will sit in the hot water cylinder. A Feltham Plumber knows about this system. Lots of properties use a mixture of both stored (above) and mains fed water. Cold water main feeds the kitchen and then from storage tanks to the bathroom, whilst all the hot water will be from a stored supply.

Water Supply

The water to your home is provide by a large system of pipework that sits underground, and originates at your local or regional water supplier or authority.

This water is subject to strict scrutiny and has to adhere to their own rules and regulations with regards to cleanliness and purity. The term for this water in the industry is ‘Potable’ (not portable). The term is from the Latin word for drinkable which is ‘Potabilis’ so you supplier actually takes it the whole water issue very seriously. The water is subject to filtration, chlorination and treated with fluoride (this helps in the reduction of tooth decay).

The Main Trunk:
The main water supply systems are known as ‘Trunk’ systems and are laid underground and feed the local mains. Feltham Plumbers understand how these systems work. The mains supply for your property is down at a depth to make sure that there is no affects from traffic or very cold weather. These pipe systems were once made from asbestos cement or cast iron in, but today it is plastic. You will see these pipes now and again when new ones are being laid. There is an isolating valve that connects the various services so that they can be isolated individually, so a supply to a new house can be made without affecting any other buildings or homes. This water pipe is then routed underground from the isolating valve to the property’s boundary, to an outside stop valve.

Service Pipe:
A vertical pipe (or chamber) is fitted so that the valve can be accessed for service and maintenance. The chamber should be clearly marked. From the stop valve the supply runs towards the property and is called the service pipe (which is medium density polyethylene or MDPE), for which the homeowner has the ownership. This (service) pipework runs under the house and in through a water meter either fitted outside or inside. This pipe must be insulated at all exposed points. A Feltham Plumber has all the knowledge and skill to work on this system.

The Compression Fitting

Used With Plastic Waste Pipework.
The compression fitting is a very flexible type of fitting that will work with lots of the materials that are used in the world of plumbing today. It will effect a watertight seal by compressing two rubber rings in between the pipe and fitting. Plumbing fittings are now the compression type because they allow a job to be constructed and broken down really easily, to clear a blockage fast. A Feltham Plumber is experienced with compression fittings.

Cutting a Plastic Waste Pipe For A Fitting.
There is a point on the waste pipe that the fitting will reach when it is slipped over. So as the pipework you must allow for the extra measurement and it will make sure that the joint is good and watertight. When the pipe is cut make sure that you file of any burrs or rough edges that are present, which can be done ideally using a half rounded file. Make sure that you pay attention to the inner edge because the water that flows through will possibly have foreign objects in it that will catch the inner edge if rough and build up causing a block in the pipework. Feltham Plumbers are experienced with compression fittings.

The most common system for the waste pipework is to fit a trap or bend using big plastic nuts at each end and a rubber ring or washer for both ends of the connection. Place the large nut over the pipework. Secondly, the rubber ring or washer. If either is tapered, fit so the taper faces the fitting. Finally, push the pipe into the fitting and tighten the nut. Hand-tighten only, as the rubber washer is quite soft and can be adequately compressed by hand.

Should the joint is leak, it normally indicates that a component is misaligned or misplaced. “

Snake For Drains

There are lots of tools on sale in many retailers for dealing with all manner of plumbing emergencies. Some of these are clever and high tech and some are just logical and simple in their use. One such tool is the ‘Snake’ that is used for unblocking drains and pipework blockages. The snake is made up of a coiled metal spiral that looks like a snake, and is normally around ¼ in diameter and in some cases can be up to 25ft in length. It incorporates a handle that is retractable. The drain snake operates in a different way than a tool like the plunger.

Once you have an entry point you can then push the Snake in the drain, begin using a twisting motion to rotate the coil deeper towards the blockage. The design lets you press into the bulk of the mass and begin to break it up.

As it has a good length it can reach deep into the pipe. It might be a job too far for the amateur. Feltham Plumbers always have the right tools for any plumbing task.

This task takes quite a lot of force when turning the handle, this makes the snake move through the various bends in the pipe. These snakes can be attached to electric drills to increases the force required to break the mass up. A Feltham Plumber uses the drain snake.

Prevention (sink block):
Place a plug hole strainer in the sink to let the water pass but catch a lot of solids from running down the drain, in either the kitchen sink, or in the bathroom.

Garbage Disposal Owners:
During operation you should always run the cold water particularly at a high speed to help the machine mash up the waste food. Keep the water running for more than a minute or so after you have finished. This helps to totally flush the mulch through the small bore pipe and onto the bigger outside drain.

Pressure and Flow

Water Pressure:
Water pressure can be explained by the example of a cylinder fitted in a loft that contains a large volume of water. The cylinder is the main feed for outlets fitted upstairs and downstairs. If we were to measure the pressure of the water downstairs we would find that it is much higher than that found upstairs. This is due to the bigger distance downhill for the water to run. Naturally the whole pressure question depends on the location and height of the cold-water cylinder.

When you have a garden hose and you open the nozzle slightly, the velocity or jet would definitely be very fast, indicating a high pressure. Now if you if open the nozzle to its maximum, the high pressure jet would fade away somewhat as a greater amount of water flows but the pressure became lower. The flow rate, however would be a lot larger.

There are devices around that can accurately read the flow and the pressure of a system. A professional plumber from Feltham Plumbers will use them. The flow and pressure information is used when planning a future plumbing system installation.

This flow rate is usually found by working out the volume of water that can flow compared to the time span. A 3ltr bucket takes 3seconds to fill up, so the rate of flow will be 1litre each second.

Weir Cup:
A weir cup is a piece of kit that is designed to measure the rate of flow by allowing the water to flow through it. It is like a measuring jug but with an outlet at the bottom for the water to pass out. It can read both litres per second and gallons per minute. If the flow rate in a system needs to be reduced, the weir cup is used, and will accurately alter the rate of flow needed to fulfil an appliance’s operating specification. A professional tradesman like a Feltham Plumber understands flow rates.

Heating Boiler

One of the most reliable appliances in the world of plumbing is the humble central heating boiler, however like most things if it is neglected it will almost certainly fail, and probably at the worst time. One of these times is usually when you need it the most such as in winter. A trained plumber like a Feltham Plumber carries the correct tools and can logically fault find, diagnose, then repair or replace any defective parts that show up on an appliance. Any failure affects you in many ways and a boiler snag can be in the control system, with components like the thermostatic control/timer or valves and pipes.

Having a regular servicing schedule in place is a good idea. The servicing can be done by you or perhaps carried out by a professional service like Feltham Plumbers with specialist boiler knowledge and all the relevant equipment.

If You Think there is a Boiler Fault:
Take some time to really look at all the aspects of the boiler and its associated pipework, where accessible, for anything that does not look correct. Check the pressure gauge and also any funny smells. Below is a small list suggesting some reasons that might cause or contribute to a boiler breakdown:

1). Corrosion that has formed inside the system pipes. Corrosion is the result of constant boiler use and the effects of the chemical reaction that occurs between water and metal which causes sludge and rust to form inside.
2). Leaking pipework, valves and radiators will cause a lowering of the system pressure which will knock on to the boiler and affect the controls.
3). Any home left empty for a long period, means that it is more difficult to restart the boiler because the water has settled. This can apply to many different appliances.
4). The older the components the more chance they have of failing as their age does have a detrimental affect on the overall performance and reliability of the boiler.”
