called _____

is a receptacle of the plumbing system accessible on floor, walls or ceiling. It is equipped with a plug or flush plate so designed as not to impair the aesthetical view of the room.

It should be sized equal to the diameter of the waste pipe, where it is to be connected. This is to avoid interference in the rodding or cleaning process.

it must be readily accessible to the plumber in case of waste line stoppage.

The ideal position of horizontal waste pipe, were those installed at _____

. Meaning, the pipe was installed with an inclined ratio of 2 centimeters per meter length.

experiments revealed that the Trap Seal Loss occurs when the grade or slope of the pipe is increased from ____.

means the loss or escape of standing water inside thé P-Trap. This is usually caused by siphonage induced by rapid flow of waste inside the pipe.

Trap Seal Loss means the loss or escape of standing water inside thé P-Trap. This is usually caused by siphonage induced by rapid flow of waste inside the pipe.

It is also referred to as ____

“The ____ diameter shall be adequate enough to serve the installation of fixtures in a general way, but the best way is to fit the diameters of commercial pipe into the fixture pattern in the most efficient manner.”

means to flush or wash out, to remove dirt or grease by flowing through. There are those who believed that by making the drainage pipe larger than what is necessary, will increase ifs service efficiency,

Drainage pipe must be of the right size to have a liquid flow of about ____ of the pipe diameter. Meaning, that the flowing water inside the pipe must have a depth equal to 1/2 the pipe diameter.

Water flow inside a larger pipe is relatively shallow. The solid waste does not flow on shallow water but tend to remain at the bottom of the pipe.

This is practically the most common cause of the many _____ of drainage installation.

For instance , if the pipe is 100 mm diameter, the water flow inside the pipe must have a depth of about 50 mm to attain the scouring action.

This is where the 2% slope becomes____

On the other hand, too small pipeline is subject to overloading of flow.

The tendency is to create ____.

Traps on the floor shall be 75 or 100 mm, and ____ for traps installed on walls with a cleanout plug.

This is only one of the so many reasons why the Standard Plumbing Code Committee, issued limitations on the diameter of waste pipe to serve plumbing fixtures.
