I have a 16X32 above ground pool. I noticed that when I opened my
pool this year, literally half the water was gone. Since then I need
to fill it every 3 days or so. I looked around the edges of the pool
and saw no signs of water...bone dry. So I chaulked up the water loss
to evaporation even though that is a lot to evaporate.
I was out mowing the lawn the other day and noticed an area around the
pool that was saturated. The water seems to go down about an inch a
day so I ruled evaporation out.
I heard about dye tests? There are pool stores around but none of
them have any type of kit. One of the stores said to use food
coloring? Any suggestions?
The 'dye test' usually means the use of a colored dye dropped into the
water near a suspected leak. The dye will be rapidly sucked into the
leak, thus disclosing it's source. I use Phenol Red, the chlorine test
dye that you probably already have on hand in your pool chemical test
My guess is that the leak is somewhere at or below the 'half full'
waterline. Are there any fittings protruding through the wall in this
area? If so, check them first.
More than likely there is a hole in the vinyl somewhere in the bottom.
Most likely around the filleted edging where the vinyl does not have as
solid a backing as the sides and bottom, or it could be anywhere else on
the bottom. Possibly done with a cleaning tool or even a toenail. Your
best bet is to get a pair of goggles, get in and inspect the whole
bottom. You may be lucky and observe an indention in the vinyl where the
combination of the water passing through the hole, and the weight of the
water above, has sunk some of the sand base into the now saturated dirt
below. You can probably patch the hole with an underwater vinyl patch kit.
If your liner is beyond its advertised life (or close to it), you may
want to look into getting a new liner.
I had to replace my 15 year old 18x36 inground pool liner 2 years ago.
It started to become porous, and had lost a lot of its elasticity due to
its going through 15 years of 80+ degree (F) seasonal weather changes.
