No. Replace the liner.
Yes, you can. The type of patching would depend on what kind of pool it is - vinyl or concrete - and what it is that needs patching. You can use a piece of pool liner and underwater liner repair glue to patch a vinyl liner (I prefer to not use the clear patch material that comes in most store bought liner repair kits, but the glue is ok to use). If it is a concrete shell, you would use a 2-part underwater epoxy made for pool repair. If the pool is a fiberglass shell, you will likely need to empty the pool to make an effective patch.
IF BOUGHT BRAND NEW IT SHOULD HAVE COME WITH A PATCH KIT. IF NOT YOU CAN PURCHASE ONE FROM A POOL SUPPLY STORE OR ANY STORE THAT SELLS POOLS.
If the rip is not tool arge you can use an undewater patch for vinyl liner with vinyl adhesive - it works underwater - you apply the adheive generopusly all ovetr the patch cut to bigger than the rip size, fold in half with adhesive on the inside, go into water to rip and unfold, smooth out bubbles and apply pressure to hold especially at the edges
That would depend on several variables. If the leak is professionally repaired and there is no damage to the substrate under the liner, then you should be fine with the life expetency of the liner. If there was a wash-out under the liner, then there is added stress to the liner at that point which can shorten it's life expectancy. If the patch is done with a clear store-bought patch kit, the patch likely will not hold very long and the liner will likely begin leaking again, which can damage the substrate and affect the liner integrity.
You can purchase a patch kit at any swimming pool retailer and use the same type of patch that is used for an above ground swimming pool liner - the kit is relatively inexpensive but it takes a while to seal but around the slash it should be clean as possible and the drier the better
patch the hole first then let it set. Take the back of your foot and try to smooth out the liner after the patch dries for 24 hours.
patching a liner is perfectly ok as long as the liner is not to old as they become brittle and glue does not stick to well - the hole is on a seam which makes it a nightmare to get the patch to seal. a patch kit can be purchased from your pool shop, dive in give hole a little abrade with 400 grit paper get out, cut your patch into a circle apply glue and fold patch. dive in and unfold patch and apply to area pressing out all air. job done - dont vac patch for a week or so. good luck Baz HIGH FIBRE GRP
