How to Fit an Outside Tap
When fitting an outside tap, you will need to shorten your water pipes first. The easiest way to do this is with a pipe cutter or an angle grinder. Before you cut your pipes, you will need to clean them of burrs and tighten the compression fittings. Connect the pipes with the compression fittings and check that they fit. Then, attach saddles and re-tighten the pipe to the wall.
Check valves prevent water flowing back up a pipe the wrong way
A check valve is a mechanical device that allows the flow of liquid or gas into a specified direction. Backflow occurs when water or chemicals flow the wrong way through pipes. A check valve ensures that chemicals or water flow in one direction and closes immediately if the direction reverses. This device is used in many applications, such as protecting filters or pumps from damaging byproducts of chemical reactions. Another use is to prevent drainage in fire sprinkler systems where elevation changes can occur. Check valves are also used to reduce pressure in pneumatic and liquid applications.
A check valve works by preventing water from flowing back up a pipe by blocking the flow in both directions. It is also known as a duckbill valve, because its soft end resembles a duck’s beak. The duckbill valve opens when water flows in and closes when it is left open. When the pressure on the inlet side is released, the duckbill valve flattens back, blocking the flow in the opposite direction.
Another type of check valve is the swing valve, which has a thin disc mounted on a hinge. The disc is lifted off the seat of the valve when fluid flows in a directional direction. If the flow reverses, the disc swings back into place to block the flow. These valves need to be cleaned regularly. They can be made of metal, plastic, or a combination of materials.
In pumped systems, a pump forces water from a lower level to a higher level. While the pump is running, the flow is in one direction. When the pump is not running, the fluid will reduce in flow back down the pipeline. Therefore, a check valve must prevent this from happening. Many standard check valves can function well in these situations. However, a check valve should be selected carefully to prevent backflow in such situations.
Adding a check valve in a plumbing system may seem like a good idea. After all, you don’t want water to come back up the wrong way. However, in some instances, a check valve can be a bad idea. In that case, you should install a valve before the pump itself. The risk of backflow is very high. If the pump is working correctly, the flow rate can be measured, but if a check valve is in the way, water can still run back up the pipe.
The correct check valve will also protect the piping system from damaging effects of water hammer. When a water hammer occurs, it is the result of a sudden change in flow. This sudden change in direction creates a hydraulic shock wave that can damage instruments and piping. If a check valve malfunctions, it can result in massive damage to piping equipment, pumps, and other fixtures.

Isolation valves allow you to cut off the water supply to a specific appliance
Isolation valves allow you to turn off the water supply to a specific appliance. Often made of copper, they allow you to isolate water pipes and appliances. You should always test an isolation valve by turning it on and off. If you find it stuck, it is best to replace it. These valves are relatively cheap and easy to install. To install an isolation valve, follow the instructions on the packaging.
The isolation valves are normally found near the water source for a particular plumbing fixture, such as a sink or a toilet. But there are also separate valves for washing machines, dishwashers, and outdoor faucets. Plumbing experts usually call these valves Ballfix. These valves are easy to locate and can be turned clockwise to isolate a particular appliance. Turning the valve clockwise can quickly solve a sink or toilet issue, allowing you to fix the problem before it becomes a bigger problem.
A gate valve is another type of isolation valve. This type of valve uses a rubber gasket to block the flow of water. It works by screwing the gate valve handle into the valve’s middle part, which means the water will not flow. You can use the gate valve to shut off the water supply to a specific appliance without disrupting the water supply. However, this is not the most reliable way to shut off a water supply, as it can break if you apply too much force.
Isolation valves are available in two different types: diaphragm and membrane isolation valves. The isolation valves are solenoid valves that shut off a specific appliance by sealing the valve seat. They can also be configured as an on/off, two-way, or three-way valve. When used for gas isolation, these valves are primarily used by utility providers.
Isolation valves help you save time and effort when it comes to fixing faucets. They also prevent airlocks from developing when you turn on the water again. So, when you want to test your isolation valves, try to turn the valve slowly and listen for water to fill up the cistern. You can also check the isolation valves that feed appliances.
You can find isolation valves for individual fixtures and appliances. Individual valves are useful in emergencies, because you can cut off the water supply to a particular appliance or fixture. The main water shut-off valve is located along the perimeter of your house on the side facing the street. If your house has a basement, you will likely have to trace the water distribution system back to the exterior wall of your home.
It is illegal to tamper with the water meter. It is also important to contact the utility company and city to gain permission before working on any water meter. If you don’t know the location of the main water shutoff valve, you can refer to the property inspection report. It is recommended to contact a plumber or property inspector to locate it. If the problem persists, call a plumber.
Installation of an outside tap
Before you can install your new outside tap, you must decide what type of pipe it needs to fit. It can be either plastic or copper. A 15mm pipe can be used. Make sure the pipe is plugged up to the wall before drilling. A small diameter drill bit should be used to drill through the wall. Then, use a larger drill bit to drill through both walls to fit the tap. Once the hole is drilled, you can install the new tap.
You should also be aware of how to maintain your new outside tap. Most of these taps come with a double check valve which prevents water from back flowing into your home’s mains. Ensure this valve is installed properly and you can also connect it to a rising main under your sink. You should also ensure that the pipework surrounding your outside tap is electrically earthed. It is best to install the outside tap in an accessible area like the kitchen and bathroom to avoid potential electrical problems.
If you are connecting the outside tap to the mains, ensure that it is installed at least 150mm above the ground level. You will need to run a 15mm pipe to your outside tap from the cold water supply pipe in your home. Be sure to connect this pipe to the cold water pipe first, otherwise you could disrupt the flow of water to the rest of your home. Once you have determined the position of your outside tap, you should drill a hole through the wall using a masonry drill with a 22mm drill-bit.
You may wish to hire a plumber for the installation. Ensure that the plumber you choose has experience with fitting outside taps. You may want to call more than one plumber for the job. Make sure you get a breakdown of the costs and consider how many different options are available for placement. Make sure you get at least three quotes before hiring a plumber to complete your outdoor tap installation. So, get three quotes, and choose the best one. You will be glad you did.
Installing an outside tap can cost you as little as PS80. Depending on the type and location, this can cost you anywhere from PS80 to PS150. Having a new outdoor tap installed in your home will make it possible to water your lawn, clean your garden, attach hoses, and even pressure wash. An outside tap should be installed close to the exterior wall and be attached to a pipe with a T-piece connection.
After the pipe has been cut and installed, the plumber should attach an outside tap to it. Then, you should secure the copper pipe to the wall plate using screws. A good place to install an outside tap is under the kitchen sink. This location is where the cold water feed comes in. Once you’ve secured the pipe, it’s time to connect the tap to the mains. It is also essential to remember that the outside tap should be connected to a water main, not a gravity feed from a tank. Installing an in-line shut-off valve is also necessary to isolate the water supply.
