With all this information on hand, I took my pump apart today, everything went as planned, removed lots of pine needles from the impeller, the pressure immediately went from 9 to 15 psi, big difference! I also put on a skimmer sock for the first time, so far so good.
I am so glad I could do this myself, my pool is about 1 year old, so far I have been doing all the up keeping myself, my PB does not do pool maintenance. Here in Toronto, Canada, I guess the economy isn't as bad as it seems, it is very difficult to get tradesman to do small jobs, my friend just bought a house with a swimming pool, when she called a well known pool company they refused to accept new clients.
Anyway, thanks everyone for the help.
