A trap on a positive drain is used to avoid the 'contaminated' air in a HVAC system from traveling through the condensate line and entering into areas where it is unwanted. The trap becomes necessary when one condensate line is used for multiple units, especially if it is tied to other negative pressure drain traps. The negative pressure drain traps may not drain properly if they have to overcome the positive non- trapped pressure of another unit. It allows the condensate to drain more evenly, as well. Without a trap, the positive pressure from the unit can blow air through the drain with the water and cause 'spitting.' A trap on a positive pressure system may not always be necessary, but it is good practice to trap every drain and trap it properly. There are guidelines for both positive and negative pressure traps. Always follow the manufacturers recommendations.

What is the answer to negative fifteen divided by positive three?
Negative 5. It's normal division, except you need to remember these rules: Positive & Negative = Negative Positive & Positive = Positive
Why do you need a positive and a negative?
Well it depends on if you are talking mathematical or scientific.
What is a negative times a positive times a positive?
A negative. If you have a string of positive and negative numbers multiplied together, all you need to find the sign of the answer is to find the parity of the negative numbers. If there are an odd number of negatives then the answer is negative and if there are an even number of negatives then the answer is positive. Remember, positive numbers make no difference to the sign of the answer.
What are the factors that will equal negative ten?
factors are the numbers you multiply together to get a product in a multiplication problem. a positive times a positive = a positive a positive times a negative = a negative a negative times a negative = a positive since you are looking for negative 10, you need one factor to be positive and one to be negative. this could be: -1*10 -10*1 -2*5 -5*2

How can I effectively unscrew a drain?
To effectively unscrew a drain, you will need a drain wrench or pliers to grip the drain securely. Turn the wrench or pliers counterclockwise to loosen and remove the drain. Be sure to apply steady pressure and use caution to avoid damaging the drain or surrounding area.
How can I remove an old bathtub drain?
To remove an old bathtub drain, you will need to use a drain removal tool or pliers to unscrew the drain counterclockwise. Make sure to apply steady pressure and turn the tool or pliers until the drain is completely removed.
Why does a shower drain need a vent?
A shower drain needs a vent to prevent air pressure buildup in the plumbing system, which can cause slow drainage or gurgling noises. The vent allows air to enter the system, equalizing pressure and helping water flow smoothly down the drain.
Why does a shower drain need to be vented?
A shower drain needs to be vented to prevent air pressure buildup in the plumbing system, which can cause slow drainage, gurgling noises, and potential backups of water. The vent allows air to enter the system, equalizing pressure and helping water flow smoothly down the drain.
What does a compound pressure gauge measure?
A compound pressure gauge measures both positive and negative pressures relative to atmospheric pressure. It typically consists of two pressure sensors, one for measuring positive pressure (above atmospheric pressure) and one for measuring negative pressure (below atmospheric pressure). This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
What dose deported mean?
Dose Deportes means Sports Dose You probably need to word it better like: "You need a dose of sports" meaning you need to try some sports or you need exercise
What does a compound pressure gauge measure in?
A compound pressure gauge measures both positive and negative pressure in a system. Positive pressure is the pressure above atmospheric pressure, while negative pressure is the pressure below atmospheric pressure. This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
Why does a washer drain need a vent?
A washer drain needs a vent to prevent air pressure buildup, which can cause slow drainage or backups in the plumbing system. The vent allows air to enter the drain pipe, ensuring proper water flow and preventing clogs.
