There are several different types of plungers available to clear partially or completely clogged drains, but all use basically the same principal. A plunger is used to create a positive or negative pressure inside the pipe to loosen the blockage and allow it to flow down the drain. As a first line of defense against any clog, a plunger is a safe bet. However, if you’re clog proves to be too much for this simple tool, your Boston plumber can handle any clog you’ve got.
This is the standard plunger that we all recognize and has probably been around as long as indoor plumbing. Consisting of a pliable rubber cup and handle, this plunger is capable of creating both a positive pressure (by forcing the cup down) and a negative pressure (vacuum) when pulled away from the fixture. Variations on the design are typically limited to the size of the cup and length of the handle.
The sink plunger; as it name suggests, is best used on sinks or relatively flat fixtures to which it can create a suction seal. When using the sink plunger:
- Cover the overflow hole of the sink or tub;
- Keep the fixture partially full of water, because water is not easily compressed it will place a stronger force on the blockage;
- Plunge forcefully in both directions for several minutes until the drain clears.
The toilet plunger is very similar to the sink plunger but has a larger cup and a fold out flap that will fit into the trap of the toilet. The flap can also be left folded in for use on sinks, floor drains and other fixtures. If used correctly, this plunger will clear nearly all toilet clogs and should be your first line of defense before calling your Boston plumber. To use a toilet plunger follow these steps:
- Fold out the flap on the plunger;
- Keep the toilet about half full of water;
- Insert the plunger so that the folded out cup goes into the drain opening and try to form a suction seal with the toilet bowl;
- Being careful not to splash yourself, forcefully plunge up and down several times and remove the plunger. Repeat adding more water if necessary.
You want to test and see if the toilet will drain once you think you’ve cleared the clog, but don’t do this by flushing the toilet again until you’re sure the clog is removed. To test for drainage you have to add water. This can be done one of two ways.
The first way is to slowly pour water into the toilet as from a bucket.
The second way is to open the toilet tank lid and SLOWLY lift the flapper seal at the bottom of the tank until water begins to enter the bowl. Do not lift the flapper all the way up or else the toilet will flush.
If water goes down the toilet easily, the clog is cleared. If not, then try again by repeating the previous step and this step a time or two more.
