MAGNESIUM:

A light, ductile, silver-white, metallic element. Its presence in high non-chelated concentrations can lead to stains & scale when conditions are right

 

MINERALS: 

Such as Calcium, Manganese, Magnesium, Nickel, Copper, Silver, Iron, Cobalt or Aluminum. Their presence in high non-chelated concentrations can lead to stains & scale when conditions are right.

 

MICROORGANISM: 

A living, breathing creature in your pool. The purpose of disinfectants are to remove such "infectants."

 

MECHANICAL SEAL: 

A seal behind the impeller which prevents water from running out along the shaft of a motor. aka; pump seal.

 

MOTOR: 

A machine for converting electrical energy into mechanical energy. Your motor is known as the dry end of the filter pump. It drives the impeller, which moves the water.

 

MPV:

A Multiport valve. (See Below)

 

MSDS:

Material Safety Data Sheet is a form containing data regarding the properties of a particular substance. An important component of product stewardship and workplace safety, it is intended to provide workers and emergency personnel with procedures for handling or working with that substance in a safe manner, and includes information such as physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill handling procedures. The exact format of an MSDS can vary from source to source.

 

MULTIPORT VALVE: 

A 4 or 6 position valve combining the functionality of several valves into one unit, revolutionizing pool plumbing. The six common functions are described below: 

• FILTER: Keep it here 99%, except when backwashing, rinsing or wastingRINSE:   Use this setting for 20 seconds after backwashing to rinse tankRECIRCULATE: Use this if the filter's broken; at least you're circulating.BACKWASH: Use this setting to reverse the flow in the filter and send water   out of the waste line. Make sure valves are open or hoses rolled outCLOSED: Put here to close off flow from the pool, usually to work on the equipment. Do not operate pump with valve in closed position

• WASTE/DRAIN: Another filter bypass setting, but this setting sends the water out of the waste pipe (hose), instead of returning it to the pool. This setting is used to lower pool water level or to vacuum to waste.

 

MURIATIC ACID: 

The liquid dilution of Hydrochloric Acid used to lower pH and alkalinity, and to remove mineral stains and scale. Extremely caustic and corrosive.
