Steve, based on what you have said and the additional comments and replies; you have a bad water pump.
They are not hard to replace, and to say the least, there is an opportunity here for you. 1) if you don't mind spending a little extra you may find a good quality water pump which good flow pressure. 2) as most people know, water pumps can be a little noisy at times, so while you have the old one out, and before you put the new one in, you can add in some sort of cushioning for noise dampening. Just some thoughts
