Need help to fix the corrode pipe in pool..!!

[Milanjohan]

Hey, I'm residing in Ontario. My son is 10-years old, and he is interested in swimming. He is going for swimming classes in his schools, and his coach asked to take more practice for it. Favourably, we have a swimming pool attained in our premise. The pool was left unused for years. Now, as my child wanted to practice swimming, I vacuumed the pool, and I tried to fill water in the pool. Since the pipe bringing water to the pool was left untouched, it created some holes in the pipes due to rust formation over it. I found that water is leaking through the small holes on the pipes, and it takes an enormous time to fill the pool. I think some corrosion check and servicing is required to fix this. If anyone has got any details regarding corrosion companies in Ontario, please help me with it. Any help would be highly appreciated.
