Resin swimming pool

[billy10]

When I have the pool "winterised " they pump out about 2 feet depth of water and put the covers on ( pool is 10 metres x 4.5 metres ) when I asked why they dont drain it I was told that you should never drain a pool completely because of the " forces in the ground" acting on the sides of the pool, anyone know if this is correct or just a bit pool mystique, I wanted to empty it so I could give it a really good clean on the sides , take out the fittings and clean them etc etc , but now I am not so sure ???

You have touched on another problem with resin Pools.

In SOME installations, hydroscopic pressure from below can cause the

Shell to 'float' out of the ground if there is not enough equalising

downward pressure. This would cause the whole installtion to break

apart including your shell if the connection to pipe work held fast

rather than yield to the upward pressure.

This all sounds pretty dire, but it will not happen immediately,

moreover having the pool empty for a day to clean would most probably

not do any harm at all. However I would choose the day carefully, not

after heavy rain and certainly not if the pool is at the bottom of

significant catchment.

Having said that I cannot see why you want to drain it completely, as

that amounts to a lot of water cycling through your place for no real

reason. If you empty it down to say 50cm then you can clean happily in

a pair of gumboots with a pressure hose and then just filter out all of

the muck. Be careful also where you send the waisted water as it is

illegal to dump it into the storm water if it might end up into a water

course.

Please note that this addvice does not apply to liner pools which

should NEVER be empied entirely, unless you are changing the liner of

course.

Thanks Andrew, see what you mean, I will empty it to 50 cm to all that I want to

I am curious how does one empty a pool in an area with combined storm and foul drains?

[Poolguy]

If its a 'public pool' that you are allowing guests to use then you are

required to have a seperate fosse and soak away. If its a private pool

then you are premitted to empty into the storm water drains PROVIDED

that you are not running a salt chlorinator. If you are then according

to Europoean law you are required to empty into an evaporation pond,

then collect the salt and dispose in the sea.(not easy)

For your sitaution BIG MAC I cannot see a solution as I do not have all

the information, so I suggest you enquire at the local Marie.
