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

Why do your drains gurgle when they drain?
They gurgle because of the sudden release of air. You have this gurgle because your vent pipes are either stopped up, in the wrong place, or are iadequate in size. When you drain water the you put pressure on the air in the drain lines. This pressure is actually sewage gas and should go out through your vent stack(s). You will need to repair or reppace your vents for this problem to be corrected.
How to determine the net positive suction head available?
To determine the net positive suction head available (NPSHA), you need to calculate the total fluid pressure at the pump suction inlet (including atmospheric pressure, fluid pressure, and velocity head), then subtract the vapor pressure of the fluid at the operating temperature and pressure. If the calculated NPSHA is greater than the net positive suction head required (NPSHR) for the pump, it is considered adequate for proper pump operation.
Can you hook up and rely on the Temperature Pressure Relief valve for a new electric hot water heater to a drain or do you really need an expansion tank?
Depends on your code. If you have a PRV or, as you would say, pressure reducing valve on your water supply to your house, you need an expansion tank. If your pressure is above 80 psi, you need a PRV AND an expansion tank.
How do you increase well water pressure?
This is done at the pressure tank. First drain the tank with pump off, then check air pressure at the tank top nipple. It should be above 26 psi. If not this is your problem. You may need a new tank or it it's a 'galvanised ' tank , a new air charge. You may also need the pressure switch adjusted, or even a new one. -Call a well technician for an expert opinion and repair.This is done at the pressure tank.

What are the different kinds of peer pressure?
Peer pressure can take on different forms such as direct pressure, indirect pressure (like influencing behaviors through actions or comments), individual pressure (when a person feels the need to conform to a group), and self-imposed pressure (setting personal standards based on what one perceives to be expected by peers).
