A step by step guide to using a power plunger

Seal off any over flows

Step 1 – Seal off over flows

Seal off any over flows. A damp towel or cloth can be used, or an alternative method would be to use a piece of tape (strong adhesive tape is best e.g. duct tape).

Remove any drain covers or plugs

Step 2 – Remove plugs

Remove any plugs or drain covers.

Choose the right size cup washer

Step 3 – Choose washer size

Choose the correctly-sized cup washer for the job.

 Fit the cup washer to the nozzle of the power plunger

Step 4 – Fit washer

Fit the washer to the nozzle-end of the power plunger. If the washer does not fit with ease, try applying a small amount of lubricant (e.g. silicone spray) onto the end of the nozzle.

Step 5 – Pump handle

The plunger will need to be made airtight (to stop air escaping). This is done by pumping the handle several times in quick succession.

     It may be easier to pump air in to the power plunger, by resting it against  a hard surface.
Pump the plunger

Step 6 – Pump again

The power plunger will then need to be pumped a further three to four times to generate sufficient air pressure in the cylinder (for delicate pipework, less pressure may be needed, so give fewer pumps).

Between 3-8 pumps is considered  the normal working range. For delicate pipe work consider using between 2-4 pumps,  to avoid damage to the pipe work.
Place the cup washer in the drain hole

Step 7 – Position cup washer

Place the cup washer in the drain hole.

Cover the drain hole completely with the cup washer

Step 8 – Push down firmly on drain

Ensure the drain is completely covered by the cup washer, and push down firmly on the drain (not too firmly if the sink is not supported by a pedestal).

Pull the trigger back to release the pressure

Step 9 – Pull trigger

Pull the trigger back quickly, to release all of the built-up air pressure in one pull.

Add water to the sink to see if the blockage is clear

Step 10 – Check flow of water

Pour water into the sink and watch to see if it flows away down the drain (this indicates that the blockage is freed). If there is still a blockage present, repeat the steps 1-8.

How do you use a power plunger in a toilet?

Power plunging a toilet To use a power plunger to unblock a toilet, the process is the same. The only differences are that the toilet will still have water in the bottom of the gulley and there are no over flows that need to be blocked off.
