Once the swimming pool has been filled, it is a rare occasion when it would need to ever be drained. Why does a pool need to be drained? Your pool contractor from Imperial Pools in Champaign, Illinois would let you know if the pool ever need to be drained and he would supervise and do that task himself.

Modern technology allows many swimming pool repairs to be effected without having to drain the pool. This is a boon to not having to refill the pool and to assuring the pool structure stays intact. Unless you are familiar with pool drainage techniques, you can seriously damage your swimming pool if you drain it without knowing how it’s done.

Why does a pool need to be drained?

Here are reasons it is dangerous for an untrained person to drain a swimming pool:

  • An in-ground pool with a vinyl liner is one of the most dangerous to drain. It should be attempted only by a pool professional. If you drain a vinyl liner pool and don’t know what you’re doing you run the risk of damaging the structural integrity because without the water to hold it, the walls could collapse into the backfilled area.  This is more of a concern in older pools, because modern pools are designed to better withstand a loss of water.
  • An above ground model. Draining and refilling an above ground pool could lead to the liner shrinking when the water is out and it may not have enough “stretch” to withstand the refilling process. Don’t ever drain a pool in cold weather as that more negatively impacts the stretch of the liner. Additionally, once you remove the water you run the risk of the pool walls collapsing.
  • A fiberglass swimming pool: If you remove the water from a fiberglass pool you run the risk of the pool “floating” on any groundwater that has built up. If the pool floats, you run the risk of damage to the plumbing and electrical system.

Bottom line. If there ever comes a time when your pool contractor believes the pool needs to be drained, he will do it on your behalf then refill it to help assure there is no damage.
