    Calcite (PH Correction) Vessel 

    Low acidic PH in water (6.5 and lower) can cause corrosion of copper pipes and geysers. This is typically seen as blue-green stains on your baths, skins, showers, and toilets.

    The Calcite (PH Correction) Vessel is designed to bring water with a low acidic PH, up to a PH between 7 & 9 (Neutral to Alkaline). 

    The Vessel is filled with Calcium Carbonate commonly known as Calcite, as the water flows through the vessel the calcite dissolves into the water. 

    The Calcite acts as a "Buffer" raising the level of PH in the water to between 7 & 9.

    There are two Types of Calcite Media Available PH Fix ( Asia) and American Made Calcite. 


    Keep in mind 

    The Calcite is essentially adding calcium (hardness/lime/Kalk) to the water in order to bring up the PH levels. Now in most cases, the amount of calcium being added is not high enough to make the water suddenly "Hard". 

    However, it is still possible for this to happen and cause lime scale build-up on pipes, geysers, and kettles. 

    To help ensure that this does not happen the calcite vessel comes standard with "By-pass" setup which will allow you to control how much of the actual total water flow goes through the vessel and is dosed with Calcite. This will help you to control the actual level of calcite being added to the total amount of water. 

    You are also supplied with some test strips which will help you to monitor the PH and Hardness levels so that you can fine-tune the amount of water flowing through the calcite unit. 


    How does it work? 


    Replacement Cost and Maintenance?


    The Calcite Vessel needs to be refilled calcite media over time, how often the calcite needs to be replaced will depend on the level being dosed and the flow rate through the unit. 

    The Calcite vessel's By-pass setup has Union connections which allow you to easily remove the piping to unscrew the valve head and add more calcite into the vessel. 

    And then replace the valve head without needing to redo the pipework or any additional plumbing.

    The American Calcite is R1 500.00 per bag and the PH Fix is R 695.00 per bag to replace.


    Vessel Size vs. Flow rate Requirements

    Please see below for roughly the size of the vessel required for certain flow rates, as well as the number of backs of calcite needed*. 

    * Please note that this is just a guide, in situations with very low PH or other extenuating circumstances more calcite and/or a large vessel may be required. 

    What is included in the price?

    The Calcite (PH Correction) Vessel comes with the following: 

    - Manual Backwash Valve (2.5") 

    - 50/75/100 Litre FRP Vessel

    - Riser Pipe

    - Top and Bottom Strainers

    - By-passing Piping Setup 

    - Calcite Media (PH Fix or American Made Calcite)

    *Please note that the flow rates specified on the Calcite Vessels below are rough estimates, the actual flow rate possible will depend on the source water ph levels and mineral content. 

    PVC Threaded and Glue Fittings

    PVC(Polyvinyl chloride) fittings are used to connect sections of pipes or tubes, adapt to different sizes or shapes, and controlling the flow of water. There are two predominant types of PVC fittings namely PVC Glue Fittings and PVC Threaded Fittings. The difference between the two is that PVC Glue Fittings result in permanent joints and PVC Threaded Fittings are semi-permanent and can be replaced. PVC Glue fittings are joined with primer and cement- a chemical solvent that melts the surface of the PVC and then quickly re-hardens to fuse the pieces together. This results in an airtight, leak-proof bond similar to what you get with welding metal. An example of such a fitting is a PVC Glue Reducing Socket which is used to join together two pieces of PVC pipes with different diameters. Another example would be a  90 Degree Elbow which is used to connect two pipes of the same diameter at an angle of 90 degrees.PVC Threaded fittings utilise a simple threaded connection whereby replaceable 'male threaded' are screwed into 'female threaded'.Male threads have a thread on the outside of the fitting and female threads have a thread on the inside. When you thread the fitting in, it compresses against the other threads.PTFE tape is used to thread these together and the proper way to assemble threaded fittings is to finger tighten, then add one to two turns but no more. An example of a threaded fitting is a Reducing Nipple Male Threaded which is used to connect between two female threads of different diameters.
