How to save time on pool and spa maintenance
|The recent east coast low that resulted in millions of dollars of damage to waterfront properties also brought the potential for problems in pools further inland. Not only can water in pools and spas be rendered unhealthy by stormwater run-off, they can also be damaged by well-meaning owners who empty the dirty water.
Swimart's national manager Chris Fitzmaurice warns owners of swimming pools affected by the recent floods and heavy rains along the east coast to not to empty their pools without first checking with an expert due to the risk of serious damage.
“Our hearts go out to those impacted by the recent floods and storms,” he says. “We understand the number one priority is cleaning out houses and making them habitable, but it must be remembered that flooded swimming pools present a unique set of hazards.
“It’s certainly not essential that a pool must be restored to use immediately, but it is vital to assess the condition of the pool and make it safe before starting any work.
“The pool shell acts as a kind of 'boat' when empty of water. If the surrounding soil is saturated, the pool will have a tendency to float, which can cause it to shift or crack.
“The fact is that all swimming pools – whether they’re vinyl-lined, fibreglass or even concrete ones weighing over 50 tonnes – can float when empty. The upward pressure of the water under the floor can actually cause it to lift.”
Most pools are equipped with a hydrostatic relief valve in the floor which will allow ground water to enter the pool to keep the equilibrium and relieve build up of pressure. However, the valve could be faulty or not able to cope with the amount of pressure caused by the ground water. Therefore it’s wise to consult an experienced technician if you must empty the pool.
Chris advises that there are a number of key steps to restore flood-affected swimming pools.
“An unused, flood-affected swimming pool is not likely to transmit or become a source of diseases in the short term unless sewage has contaminated the pool. However, as it generally won’t be filtered or sanitised, it is important to check for evidence of mosquitoes on a daily basis,” Chris says.
