Use fiber restoration kit to seal the leaking points . There is no need to replace the water tank.

Sorry for the confusion, it is fiberglass restoration kit / patch. Last time I bought this product to seal the leaking points.

The resin , after it dried off, it won”t have further reaction. The purpose of the resin is to melt the fiberglass, the fiberglass is actually a type of glass.

Replacing the tank, this should be the cost involve :-

Rental of crane - smallest in the market 25 Tons = RM 600 for 1/2 day, if they don't rent 1/2 day, then need to pay for full day around RM 1200~1500.
Removal of roof tiles & placing back roof tiles = RM 600
New PE water tank (330 igal) = RM 800
Installation of joints, valves, etc = RM 400.

Total worst case = 1500 + 600 + 800+ 400 = RM 3300.

That should be the range you are looking at.

If seal back, own DIY - fiberglass restoration kit = RM 25~30. 1/2 day labour sendiri buat = RM 0. Total cost = RM 25~30.

Hence it will be RM 3300 vs RM 30.
