POOL LINER CHANGE

Home Counties Swimming Pools carry out many Liner Changes each year.

When should i change my liner ?

What is the process of changing it ?

Liner Change Process

Empty and measure the pool.

• Empty the pool of water
• Remove liner and dispose
• Remove underlay from floor if present
• There is not always underlay on the floor as not all pool companies fit it, we always do
• If underlay is present on walls then remove it to inspect the walls
• Take accurate measurements of pool

Portapools

• Where possible and practical to use portapools to store water in prior to the refitting of a new liner

Pressure test the pipework

• Pressure test pipework from all fittings back to the plant room
• Provide report of pressure test results

Replace hydrostatic relief valve

• If present replace the hydrostatic relief valve, this is the only opportunity to replace such whilst the pool is empty and the rubber ‘O’ ring within them does eventually perish so this is done as a precautionary measure

Check and patch floor

• If there is any minor damage to the floor then patch this as necessary
• If the floor is completely degraded then it may need a complete re-screed though this is very rarely the case

Check and patch walls

• If there is any damage to the walls then to patch them accordingly

Check copings or coping stones

• Copings and coping stones are check for sound adhesion
• Any pointing under the copings at the face of the pool where the liner is fitted is checked and any loose pointing replaced with a white sand / cement joint mix
• Copings to be cleaned with pressure washer or by hand

 Clean and check the white goods

• Clean and check any white goods on the pool, skimmers/return/main drains etc
• Looking for any damage including cracks and checking screw holes

Underwater Lights

• Check the operation of the underwater light and replace lamps as necessary
• Also check the housing for damage and the cable gland to see that it is secure and watertight

Supply new gaskets and faceplates where available

• Source and supply new gaskets to all white goods where possible
• Occasionally these are found to be redundant item for which new faceplates cannot be sorced
• On these occasions it is sometimes possible to clean and re-use the old faceplates or possibly have new ones custom made
• Some roman end in particular have faceplates that cannot be sourced as replacement and having one made is not possible, often with these we are able to use generic faceplates

Wash pool

• Wash pool floor down with sodium hypochlorite prior to fitting the liner to make sure there are no contaminants present nor algae growth within the screed

Fit liner

• Lay new 4mm felt underlay to the floor
• Fit new 8mm foam underlay to the walls, glued in place
• Fit new gaskets to the white goods
• Fit new 30 thou liner and vacuum into place
• Fill with water whilst fitting the faceplates at strategic points

Linerlock

• Fit either linerlock or linerlock cover up wedge as is felt appropriate

Ladder bungs

• Replace ladder bungs as these pose a real problem to pool liners if they should wear through

Shock dose

• Shock dose the newly filled pool with chlorine

Chemical balance

• Check and adjust the chemical balance of the pool
• Provide report as to the chemical balance

Warranty

• Hand the pool back to the client and supply warranty and care advice for the new liner
