Usually it's better to start your own thread so that you can get responses specific to your issue. I've moved your post to a new a thread for you.
So what issues are you having with your water pump?
Oops. I guess I jumped the gun. Didn't see you had already posted another thread. Folks please post on thread "water pump issues along with plumbing" rather than this one.
