Ever notice those float switches getting gummed up on the primary? I kinda like the idea of a float switch on the secondary only so I get full flow on primary and the float switch never sees water if the system is draining correctly...

Does the pipe dries in winter when the AC isn't working? letting the smell goes into the system?

Thanks brother

Great, right to the point video. I installed an ez trap on my 80% Rheem furnace. Gas Furnace sits upright with A coil on top . Question - does the ez trap ( p trap) need water in it in the winter when a/c not used? If it does, to prevent freezing since my furnace is in the attic , should I use RV antifreeze in the p trap or is just insulation around the p trap enough. Live in cold New Jersey. Much appreciated!

@WorldofHVAC

Жыл бұрын

Is that a downflow furnace? In my area that system you described would be a positive flow and doesnt require a trap at the system.

@AAtta-3286

Жыл бұрын

@@WorldofHVAC No, it's an upward flow, so negative pressure. The fan is at bottom and A coil on top. Without P trap, condensing water won't flow out but sucked in. So I'm concerned with p trap freezing if water needed in winter. The condensing tube drains to the outside not into any fixture or sewer. Much appreciated if RV antifreeze needed or if water needed at all in winter when a/c not used and insulation enough.

​@@AAtta-3286you're a bit confused on the subject. If your fan is blowing through your coil (how you described your furnace) you have positive pressure drain. Therefore no need for a trap. On the other hand. If your fan is pulling air through your coil that will cause a negative pressure in your drain and you will need a trap. Think about it.

CODE STATES THAT P TRAP ON NEGATIVE PRESSURE SIDE MUST BE 1 INCH HIGHER THAN RETURN STATIC PRESSURE, SO ANYONE WHO USES A PREMADE TRAP IS DOING IT WRONG. PERIOD. Example - if your return static is -.03 inches in WC. You must have a 4 inch drop off tee from main drain port then with a 2 inch rise to the vent tee. Another example if you have -.1 inches of static on return you must have a 2 inch drop from tee that connects to main port with a 1 inch rise to vent tee. Also anything in 3.5 ton or higher should be 1" drain pipe not 3/4

Nice job. Question In some regions, the ac is not used for several months over the winter, so will the trap go dry and the sewer gas return? Does the trap have to be larger?

Usually thats not the only trap on the system. Plumbers have an 1 1/2 trap going into their stack. I havent seen the water get sucked into the unit or dry up before. Wouldn't hurt to check it periodically

Can I cut the tip of the p trap pipe by half an inch to help create a downward drain flow ?

Package unit definitely. Split system would be negative flow. And heat pumps follow the same rule as positive and negative airflow applications. Heat pumps change the refrigerant flow not the air flow.

Never swab glue inside a fitting, always swab glue around the pipe. When you glue the inside of a fitting, you're pushing all the glue back inside the drain when pushing the pipe in the fitting.

This is good comment 👍

So confused about the P trap. We bought our 2-story condo with an AC in a closet at the top of the stairs. A white PVC pipe comes out of it that angles down and out of sight. That PVC pipe has one of those shut off floats cut into it, but no P trap. Another pipe comes out which is covered in a black pool noodle cover, heads along a parallel path with the PVC pipe but at a height above it. Again, no P traps. Was this old school, or incompetent work? The AC works with no leaks. Do all ACs need this P trap? The shut off float I described is also the only way to pour in vinegar or bleach to clean the drain pipe. Does that matter?

@WorldofHVAC

From my experience, second floor vertical systems have a plumbing trap extremely close to the unit. If the plumbing trap is within a certain distance an additional trap is not needed at the unit. Also depends on the system. A positive pressure system like a gas furnace does not need a trap at the system. The black pipe is the suction line connecting the evaporator to the condenser. That pipe gets cold and will sweat when its running. Insulating that pipe will help prevent water damage. Dont pour bleach down the drain. The funes are corrosive. Use vinegar when maintaining your drain.

the insulation really obstructs the view of the pipes and their connection. Why can you not put the pipe insulation on after all the connections done ?

@WorldofHVAC

10 ай бұрын

I like to keep the insulation as one solid piece. Attics in my area are 130+. The tape tends to fall apart, which results in sweating and that turns into water on the ceiling.

I've seen/worked on a lot of AC systems both horizontal and vertical, and none had the coil on the negative pressure side. So no ptrap needed. This is in Texas. Maybe it's different in other parts of the country.

Finally figured out that you were talking about heat pump systems, in which the coil should indeed be on the negative side of the blower. In my area, almost everybody heats with natgas because it's cheaper, so the AC/furnace systems put the coil on the positive airflow side after the heat exchanger. Excellent video by the way. We're planning on building in an area with no natural gas available, so we'll have heat pumps (and p-traps!)@@WorldofHVAC

so obviously youre venting the line into an existing sewer drain. My system upstairs is in the attic and the condensate line exit the house thru the eaves & into the gutter. Is a P-Trap still rcommended? I want to redo my connections & at least put in a cleanout. Great video

Depends on the position of the blower in relation to the evaporator coil. Furnace forces air across the coil. Thats a positive flow. Air handlers draw air across the coil. Thats negative flow.
