Washing Machine Installation Guide: Pipe, Tap and Drain Hose
A correctly fitted washing machine fills faster, drains properly, does not leak and lasts longer. This guide explains how to connect the inlet pipe, drain hose and power for automatic, twin tub and single tub machines.
Updated 11 November 2026
What you need before installation
- A tap within reach of the inlet hose, ideally a 3/4 inch washing machine tap or a two way tap.
- A floor drain, standpipe or sink outlet for the drain hose.
- A grounded (earthed) socket near the machine, not an extension board.
- A flat, firm floor. Avoid soft rugs.
- A spirit level, a spanner and some thread tape.
Automatic machines need steady tap pressure. If your water comes from a low tank, choose a model that works with low pressure, such as the Kenwood KWM-10005FAT 10 KG Inverter Top Load Automatic Washing Machine, which lists near-zero water pressure operation, or a twin tub that you fill by hand.
Remove the transit bolts (front loaders)
Front loaders and washer dryers come with three or four transit bolts at the back. They lock the drum for transport. Remove them with a spanner and fit the plastic caps in the holes. If you run the machine with the bolts in, it will shake badly and can be damaged. Keep the bolts in case you move house.
Connect the inlet pipe and tap
- Screw the inlet hose to the machine's water inlet (top back on most top loaders, lower back on front loaders).
- Screw the other end to the tap. If the tap has no thread, use a tap connector or adapter.
- Make sure the rubber washer is inside each end. Hand tight plus a quarter turn is enough.
- Open the tap and check for drips.
Some machines have two inlets for hot and cold water, such as the Dawlance DWT-1580 INV C Glow 15 KG Inverter Top Load Automatic Washing Machine. If you have no hot line, connect cold only. A two way tap lets you share one water point between the machine and a sink.
Fit the drain hose at the right height
The drain hose must take used water away without letting it flow back.
- Top load automatics and front loaders: hook the end into a standpipe or over a sink about 60 to 100 cm high, or run it to a floor drain, as the manual says. Too low and the machine may siphon water out while filling; too high and the pump struggles.
- Twin tubs and single tubs: the drain hose usually just goes down to a floor drain.
- Do not push the hose too far into the standpipe and leave a little air gap.
- Do not kink the hose behind the machine.
Need a longer drain hose? Use an extension with a proper connector and a clip, and keep it as short as you can.
Electrical connection and voltage
Plug the machine straight into a three pin earthed socket. Avoid extension boards for automatics and dryers. In areas with low or unstable voltage, use a stabiliser or pick a model built for it: the Dawlance DWT-9060 EZ 9 KG Top Load Automatic Washing Machine lists operation down to 150V, and the Haier HWM130-B699S8 13 KG Inverter Top Load Automatic Washing Machine lists a wide voltage range of 160 to 260V.
Keep the socket above floor level and away from splashing water, especially in a bathroom or open balcony.
Level the machine and do a test run
Put the machine in place and check with a spirit level on top, front to back and side to side. Turn the adjustable feet to raise or lower each corner, then lock them. A level machine is quieter and shakes less in spin. A stand with wheels makes cleaning easy, but choose a strong one with locking wheels, as a loose stand makes vibration worse.
Then run a short empty program (Rinse and Spin or Quick Wash). Watch for leaks at the inlet and drain, check that water drains fully and that the drum spins without banging. On a twin tub, fill the wash tub, run the wash timer for a minute, drain, then test the spinner. Then follow how to use and clean a washing machine for your first real wash.
Installing a twin tub or single tub
Semi automatic machines are the easiest to set up. Place the machine near a floor drain, hang the drain hose down to it and plug into an earthed socket. Most twin tubs have a water inlet on top that you can connect to a tap with a simple hose, or you can fill them by bucket. Machines with two water inlets, such as the Dawlance DW-6580 8 KG Twin Tub Washing Machine, let you fill the wash tub and use the shower rinse in the spin tub.
Keep the machine on a dry, flat spot, because water often splashes during manual transfer of clothes. Raise it a little on a stand if the floor gets wet. See twin tub washing machines and single tub washing machines.
Covers, rat guards and outdoor placement
Many homes keep the machine on a roof or balcony. Sun and rain damage plastic panels and control boards, so use a waterproof cover that fits your size. Some models have a rat-proof base, such as the Ecostar EW-F1204DC 12 KG Top Load Automatic Washing Machine and the Ecostar single tubs, which helps where rats chew hoses and wires. Never cover the machine while it is running, so air can flow.
Installation and fitting cost
Many brands offer installation for automatic machines through their service network; ask the brand after delivery. A local plumber can fit a tap, adapter or longer drain hose for a small fee. Twin tubs and single tubs need almost no fitting: plug in, place the drain hose and fill with water. Delivery from us takes 48–72 hours after advance payment, all over Pakistan.
