piercing valve

Piercing valves provide up to more sealing area than competitive O-ring types. Piercing needle is designed for concentricity and hardness to insure perfect seating every time. Valves with a knurled control knob offer more easy flow control.

How does self piercing water valve work?

Also known as a refrigerator water shut-off valve, most saddle valves are self-piercing. This means that, once clamped on the pipe, the valve handle can be tightened until it pierces the pipe with no drilling or cutting involved.

How do you know if your refrigerator needs freon?

Listen. With your ear pressed to the refrigerator, you should hear a faint hissing or gurgling noise. The Freon will hiss and gurgle through the fridge’s capillary tubes as the pressure equalizes within the system. If you do not hear the hiss and gurgle, you may be low on Freon.

What is R600a refrigerant?

R600a is an HFC-free refrigerant with no ozone depletion potential and a lower global warming potential compared to earlier refrigerants. By January 2022, all household refrigerators (except for larger built-in refrigerators and freezers) will be required by regulations to use lower global warming refrigerants.

Why should solderless type piercing valves not remain installed?

Solderless piercing valves are generally used to access refrigerant during service and should not be left on the appliance afterwards. This is because they tend to leak over time.

Is R22 a freon?

If your home’s air conditioning unit is more than 10 years old, there’s a good chance it uses R22, commonly known as “Freon.” R22 is an A/C refrigerant — a substance used for cooling in air conditioners— that was once widely used in air conditioning units in homes and businesses alike.

Where is the low side on a refrigerator compressor?

The low side line of the system will have a larger diameter metal pipe than the high-side. The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed.

Can you open a saddle valve too far?

As far as opening and closing the valve, don’t worry about it. The saddle valve only pierces the pipe once. After that there is no further increase in the size of the opening. There is no additional stress placed on the valve by opening and closing it.

Will a saddle valve work on PVC?

Most saddle valves are designed to work with standard rigid copper pipes—they are not recommended for PVC, CPVC, or PEX plastic pipe. They are also designed for water systems with a maximum pressure of no more than 125 psi.

How do you clear a blocked capillary tube?

If the tube is blocked because debris has got past the filter/dryer and partially, or fully, blocked up the capillary tube there is an easy way to clear the blockage using this small modified hydraulic bottle jack. An old used jack can be used and the pump plunger “O”ring can be replaced if it is leaking.

How do I fix my refrigerator that is not cooling?

Clogged coils can cause poor cooling. Check to make sure nothing is stuck in the condenser fan and that it spins freely (models with coils on the back won’t have a fan). To do this, unplug the fridge and pull it out. Clean the fan blades and spin the fan by hand to see if it’s stuck.

What happens if you put too much Freon in a refrigerator?

If there’s too much freon in a refrigerator, the compressor motor can burn out. This impedes the fridge’s ability to cool and renders it ineffective. In some cases, the surrounding components can be affected causing the fridge to die. To fix the issue, reduce the freon use an extractor.
