The multiport valve is the main flow control valve on a swimming pool sandfilter, the most used filtration system in South Africa. The MPV has 6 settings to direct the flow of water from the swimming pool through the pump and filter.

Automatic pool cleaning | What’s best for my swimming pool?

Pool cleaners

Nowadays homeowners have a variety of alternatives when it comes to cleaning their pools. They can hire an outside pool professional, use their own time and muscle or if they are in the process of building a new pool, include an in-floor cleaning system.  Many of us turn to automatic pool cleaners (APC) however, because they save time, are easy to use, and are quite efficient.  Here are a few tips to help you decide which automatic pool cleaner is best for your pool.

What are the types of automatic pool cleaners, and how are they different?

There are three types of automatic pool cleaners available in South Africa:

  • Robotic pool cleaners;
  • Pressure-side pool cleaners; and
  • Suction-side cleaners

Robotic cleaners are compact and self-contained machines that move themselves around the pool,  sucking up dirt and debris while also rotating brushes or rollers to scrub surfaces.  These types of cleaners do not use the pool or booster pump to start.  Some use a water-safe electrical cord that is plugged into a 3-point plug, while others operate with a chargeable battery or solar power.  These robot pool cleaners “learn” the pool shape wit its first dive into a new swimming pool and thereafter clean cover the interior pool surface 100%.   Prices range from R10800 at your local online pool shop up to R58000 for the bigger robot pool cleaners that covers a 60m long pool.

What is a Chlorinator? | Convenience, the experienced pool owner’s choice

How do Pool Chlorinators Work?

 

Chlorine in one form or the other has been in use in a wide variety of industrial applications for a long time, and in that time we have come to understand it extremely well. Although there are some people who believe chlorine in pools poses a safety hazard, clinical studies have found no such link – either to swimmers or the environment. This is why nearly every pool in South Africa continues to employ chlorine as a free-ranging antibacterial agent, keeping the water clean and clear and maintaining an essential level of purity for recreational use. If you own a pool, however, you know that regulating chlorine can represent something of a hassle.

The reason for this is actually quite simple: chlorine breaks down over time when exposed to sunlight. Although hypochlorous acid – the essential byproduct when you (more…)

How to acidwash a pool

Published by Swimming-Pool-Expert on June 24th, 2011

Acid Washing

You will have to drain and clean your pool before you start. An acid wash becomes necessary if the pool has turned into a swamp. This may occur if the pool has been stagnant for a period of time so that algae has taken over.

The general rule of thumb for determining the need for an acid wash is: if you can see the bottom of the pool (the floor) then you can bring it back with chemicals, labour and filtering. If the floor is not visible, the cost of the chemicals and labour will generally be greater than the acid wash charge, and take much longer. Also, extensive algae blooms will stain plastered pools, making an acid wash desirable and if there are any other stains maybe from metals.

An pool acid wash is, put simply, purposeful stripping of a tiny layer of liner, exposing fresh plaster beneath. Therefore, it is not advised to make it an annual custom, which will accelerate the need for re-plastering. Most plaster coats (sometimes called marble plaster or marblite) are in excess of 8mm, so a few careful acid washes should not hurt.

You may also decide on an acid wash not because of swamp conditions, but just to bring out a brighter, whiter finish. Mineral stains caused by excessive (more…)
