ABOUT VINYL

Vinyl Liners

Since 1960 vinyl lined pools have been produced in South Africa providing a cheaper, more durable, lower maintenance and affordable alternative to fibreglass and gunite pools.

These vinyl liners are manufactured from durable PVC which had been HF welded into the required shape and size. These liners can be installed in shells constructed out of cement blocks, bricks, aluminium, wood or steel panels, and a sand base.

Features & Benefits

There are 5 immediate advantages to vinyl swimming pools

1. Permanently coloured vinyl eliminates painting of the pool
2. Algae will not stick to the smooth surface
3. Elasticity of vinyl allow for wall and floot movement without leaking
4. Pool never needs emptying for maintenance
5. Simple and inexpensive construction

Care and Maintenance

1. USE CORRECT CLEANING EQUIPMENT

Any equipment not designed specifically for use in vinyl pools may tear or scratch the liner.

2. WATER FILTRATION

The filter removes fine suspended particles before they settle to the pool floor. A skimmer weir box is recommended to remove floating debris.

3. CLEANING

Although vinyl is easier to clean than other surfaces, we suggest that prevention is better than cure. Prevent debris from collecting in and on your pool for the following reasons. Viz:

Organic matter, such as leaves, worms etc weaken water purifying chemicals.

Decomposed matter can stain your pool.

Items with steel or iron content cause rust stains.

Chlorine solids will bleach the liner if left in contact for extended periods.

Chemical Water Treatment

pH CONTROL

The pH factor (degree of acidity or alkalinity) should be maintained between 7.2 and 7.6. Use a pool pH test kit to regularly check the pH and adjust it using the correct chemicals.

WATER CHLORINATION & STERILISATION

Discolouration of the swimming pool water is usually caused by bacteria falling into the pool and growing into greenish algae. Dailyaddition of chlorine prevents this growth. A larger dose is required during warm weather. Always remember to add chlorine at sundown as the heat of the day tends to evaporate it from the water.

The various type of chlorine include:

1. Calcium Hypochlorite
2. Sodium Hypochlorite
3. The pill
4. Auto salt chlorination

Fault Finding

a) WATER CLEAR, SIDES OF POOL SLIPPERY.

This is an indication that algae is starting to form. Check pH. If incorrect, add Hydrochloric acid and a double dose of chlorine. Repeat daily if necessary.

b) WATER SLIGHTLY TURBID AFTER EXCESSIVE SWIMMING

Check pH. Add double dose of chlorine. Run filter continuously until water is clear.

c) WATER TURNED GREEN (FROM ALGAE)

Correct pH by adding hydrochloric acid. Dose heavily with chlorine. (70-80gm per 18 000 litres water). Allow dead algae to settle over 2-3 days. Vacuum up dead algae running to waste.

d) WATER TURNED BROWN (INDICATED BY pH READING - < 7)

Correct by adding soda ash. (70-80gm per 18 000 litres water). Allow iron to settle over 3-7 days adding chlorine every day. Vacuum up settled iron running to waste. Filter out balance of iron, backwashing filter frequently.

e) STAINS

Sulphuric acid causes stains and therefore we recommend that you only use hydrochloric acid.
