Prefabricated pool owners often make some fatal mistakes when installing and operating their prefabricated pools.
In this article, I will point out four basic mistakes that, if avoided, will allow you to enjoy your pool for many years.
- I often get asked whether it is possible to avoid pouring a concrete bottom at the site where the pool will be installed. There is only one unequivocal answer: a concrete slab must be poured at all costs. Depending on the size of the pool, up to 1.5 tons of water pressure is generated per 1 m2. Any other foundation other than concrete is unpredictable, even if it looks very strong
- Another common mistake is to save on making a backfill with damp concrete behind the pool walls. In in-ground pools, a backfill is mandatory. The earth mass exerts a lot of pressure on the pool walls. When it is full, there is no problem. But when the water is drained to half during wintering or when all the water is drained during cleaning, then the dirt can damage the structure if there is no protective belt.
- Connecting the filter system to the pool using a 38 mm blue hose is another mistake that should be avoided. This hose can only be used for short distances or for above-ground pools for temporary use. For longer distances between the filter system and the pool, a 50 mm or 63 mm rigid PVC pipe or a flexible PVC connection should be used. The blue hose provides a lot of resistance. For large distances between the filter and the pool, the pump power will decrease significantly. Example: a pump with a capacity of 5 m3/h with a 10 m long rigid PVC pipe will lose 0.01 bar of its power. With 10 m of 38 mm blue hose, the loss will be 0.16 bar.
- It is wrong to completely drain the water from the pool during winter storage, because then there is a risk that the pool will be damaged in strong winds or be swept away when the groundwater level suddenly rises. The pool should be drained halfway during winter storage.
