Water Inlet

Washing machines will always require a hookup for the water supply and at least one line for cold water.

Additionally, some washing machine models need dual supply lines for hot and cold water separately.

That being said, some modern-day washing machines even have a built-in water heater and do not need a separate line for a hot water supply.

So, depending on the washer model and the location where you want to install the washer or washer and dryer combo, you will need to have the supply lines installed by a professional plumber.

If you already have a water tap installed in your laundry room or near the space selected for the washing machine, you simply need to connect the water inlet hose.

Drain pipe

The drain system is another important thing to consider before you hook up your washing machine.

It plays a key role in discharging used water after completing the washing process.

The drainage system should be checked to ensure it can handle the amount of water being discharged, and that the drain pipe is not bent or kinked.

The standard or average length of the washing machine’s drain hose is around 5 feet long and can be extended up to a maximum of another 5 feet, making it a 10-foot-long drain hose.

Note: Extension of the drain hose beyond the maximum or allowed length can lead to poor drainage or even flooding.

Factors that you should consider before hooking up the dryer


Some gas dryers require a 120v electrical circuit and a 3-prong grounded outlet, and some may require a 240v electrical circuit and 4-prong grounded outlets.

Electric dryers use electrical power to generate heat; hence, the requirements of electrical circuit outlets and the number of prongs required for operation vary.

So, before installing the dryer, it is important to check with a professional electrician to ensure that the electrical wiring and outlets in your home can support the dryer’s electrical requirements.

Additionally, it is essential to confirm if the dryer requires a three- or four-prong outlet to prevent any electrical hazards or damage to the machine.


There are typically two types of dryers, i.e., ventless and vented dryers.

Ventless dryers will not require any additional hookups to discharge hot air out of your home.

These dryers usually use a condensing system to remove moisture from damp clothes.

Vented dryers will need the installation of an exhaust vent to discharge hot air.

Gas supply

Usually, gas dryers use natural or propane gas to generate heat and dry your clothes.

These dryer models require an additional hookup for gas supplies, such as supply lines and shut-off valves.

It means gas dryers typically require a gas hookup and a vent to safely release the hot air from the exhaust.

Drain (Ventless dryers)

Some dryer models are ventless and do not require any exhaust vent installation.

But some ventless dryers may require a drain connection to expel the condensed water.

If your dryer model has a built-in tank to collect water, then you may not need to install a drain pipe separately.

However, make sure to empty the tank manually as required or after every dry cycle.

Combo units

Combo or all-in-one machines include a washer and dryer in a single unit.

These types of units are usually ventless in most cases.

The electrical circuit requirement can vary from 120v to 240v, likewise, a 3-prong or 4-prong grounded outlet is a must (depending on the appliance’s power consumption).

And of course, drain installation is also required for combo units to discharge used water after every wash cycle.

Common types of washer and dryer Hookups that you can try

There are different types of washer and dryer hookups that you can choose based on your preferences, the dimension of the laundry room, and the type of appliance.

That being said, here are some common and successful types of setups that you can try to ease your laundry tasks.

Side-by-Side Hookups

Side-by-side hookups are the most common type of setup, and they are usually designed for traditional washing machines and dryers that are placed side by side.

The hot and cold water valves, as well as the drain, are typically located behind the machines.

Stackable Hookups

Stackable hookups are designed for compact washing machines and dryers that can be stacked on top of each other.

Just like the side-by-side setup, the hot and cold water valves, and the drain are located at the back of the machines.

Combination Hookups

Combination hookups are designed for all-in-one washer and dryer units.

These units are becoming more popular because they are compact and take up less space.

Furthermore, the combination hookups have one water valve and one drain that connect to the unit, thus making it a space-saving option.

Pedestal washer and dryer

A pedestal washer and dryer is a newer option that involves placing the washing machine and dryer on a pedestal.

This can provide extra storage space underneath the machines and can also make them easier to access.
