Over time your pool will some require maintenance and repair. The important thing is not to leave
Not only that, but the fault will not repair itself and may only get worse causing
After time (around 5 to 6 years) your sand may need changing in the filter.
This can cause misty pools.
When this happens then it is probably time to get the sand replaced. I will also replace the spray bars at the bottom of the filter as they can become brittle and if one of them breaks then sand will be pumped into the pool.
Occasionally a selector valve will fail causing a substantial loss of water as it flows freely down the waste pipe even when the lever is in the filter position. I will check that this is not happening once a week when I am maintaining the pool. Signs that the valve is starting to fail are water sitting in the recesses of the lever and the pool starting to need a little more water than usual. If this happens then call me to check before its to late and causes more costs than you needed.
