Installing Washing Machines & Dishwashers

The installation of such commonly used appliances is a complex task and several rules should be followed to avoid unpleasant issues connected to the process in the future. Excellent Plumbing prepared a couple of hints for that, so you will be sure your appliances work effectively and will serve you for a long time.


Choosing the correct location or preparing the place for a washing machine or dishwasher in advance is an essential step. You should consider than any of these appliances require not only space according to its parameters, but access to cold and hot water, and a socket.You can argue that the hot water supply is unnecessary because modern tool heats the water according automatically according to selected programs, but it’ll also cost additional energy consumption and will be more expensive. Thus take care of both types of water supply.Another important thing to pay attention at is the water pipe’s situation, which is highly recommended to be as close as it possible during installing of both types of machines (washing as well as dishwashing). The best practice is to install these devices close to the sinks, so the dirty water will be properly disposed of and will not get back into pipes for reuse.Tip: before starting installation don’t forget to turn off the supply of the water.



The first thing you should do is to install special valves for water supply to appliances from hot and cold water pipes. Considering a variety of valves choose the most suitable for such cases t-piece type, which has colored handle marked to distinguish between hot and cold sides.Installation of the valve to the pipe required to cut the hole of the respective size just in the pipe. Thus, the best way to do it is to put down the valve to the pipe, then cut the hole suiting valves diameter, clean it carefully from all the waste so the only material observed at the place of cutting will be cooper, and put the valve there. Connect the appliances’ hose to the central valve’s hole.Olives together with nuts should be put to pipe’s ends. Tight nuts, compress olives thoroughly inside the valve. Check the placement of the rubber washer (it is black). It should be inside the nut made of plastic which belongs to appliances’ hose. Ensure the hose was thoroughly screwed to the valve’s outlet.For cases when the washing machine/dishwashers are situated far from the pipe you might need to insert not hose to the valve, but the copper pipe. Add another valve to the end of the new pipe in order to make a connection between the pipe and appliance.Another option may be available after checking all types of valves which are available in the plumbing shop located near the place you live in. For example, speed fit connection type of valves consider connection by pushing onto the pipe’s end with a washer lock inside of it. So it is secured properly to the pipe. Another option is using of the self-cutting type of the valve, which clamps to the pipe, while a special turning handle can cut the pipe. The hose connection is performed in the same way described above.


As was mentioned above for proper wastewater removal it is recommended to place machines close to the sinks. In such a case replace waste fitting by fitting from the appliance connecting the hose directly to the nozzle. Ensure joints are properly sealed. For other cases install standpipe near the wall. You should also connect it to the existing drainage system.Tip: Wastewater must be disposed of via a special trap. The respective hose must go down the standpipe having a distance separating the trap and the tube. The waste pipe’s end must be lower than the drain’s grid.In case you have some additional questions, need consultancy or help call our experts at +1847-868-1800 and you’ll get all you want.
