How to Winterize Your Hot Tub - Winterizing a Spa 

In this short article we'll look into six indispensable AC vacuum pump parts and AC vacuum pump accessories: Pump hoses, Pump adapter, Inlet fittings, Refrigerant identifier, Can tap valve-screw-on, and Vacuum gauges. Vacuum pump hoses You best get the pump hoses that are UL (Underwriters Lab)

The typically T-shaped inlet fittings on an AC pump will allow you to keep two hoses connected simultaneously to the AC pump, making the setup one phase rather than two phase. Just switch from one inlet to another when needed.

Refrigerant identifier

Refrigerant identifier is an important device that will let you know in an unfamiliar system, what type of refrigerant substance you are dealing with before you embark on the service or repair. These days, in search of a ozone-friendly, non-flammable, non-toxic, and actually useful refrigerant, many different substances are used that require much different handling and even much different equipment. So be sure to get a refrigerant identifier rather than working in the dark.

Can tap valve-screw-on

These are always useful to cut off the vacuum pump-hose connection when needed.

Vacuum gauges

Nothing is more important than a good set of vacuum gauges in order to know when your job has been successfully completed. Be it for measuring the ultimate quality of the vacuum, or for finding out the presence of leaks in the system, vacuum gauges are indispensable.

A heat pump is not a ventilation system. Ventilation systems introduce fresh air into the area and they may also heat the air on the way. The heating part is like any other electrical heater and for every dollar spent on heating you will get a dollar of heat in your room. Air conditioners actually only introduce heat and there is no heating element needed. For every dollar spent in heating you will actually introduce at least three dollars worth of heat into the area. With a fuel tank half full, the upper part can cause condensation.

This condensation will slowly build up and run down into the bottom of the tank.

When you start to pass another vehicle you call upon the fuel pump to give me more gasoline.

The fuel pump starts working overtime and picks up more fuel, then the water goes into the line along with the gasoline.

The fuel filter catches this water and since water is heavier than gasoline, it drops to the bottom of the filter.

After awhile though, you come up behind me, and I'm not driving quite as fast as you would like to go, so you floorboard it and go around me.

What happens when you floorboard it?

Right, you are asking for more fuel.

With the filter partially full of condensation, water, some of it gets picked up into the fuel line and goes to the carburetor or injector.

"Chug-a-lug, chug-a-lug, Pow!"

Purr, purr, purr.

See what happens?

You can solve this problem, most of the time, by changing the fuel filter two or three times a year.

Now, if you have just filled up at the pump, and your car starts acting this way, you may have to take the fuel tank off and clean it out.

Or, pay someone else to do it!
