The guy coming in the morning is going to replace it with rubber couplings.
We truly are pond newbies. We moved into this house in June 2014 and had never taken care of a pond before. The only input we got from the sellers was "there's fish in it" lol. They did not clean it at all and it was a MESS when we moved in. I was able to get it cleaned out pretty well last summer but we had so much other stuff going on with moving and whatnot that it kind of got lost in the shuffle. I was able to get it clear with AlgaeFix, barley bales, and did get a vac that uses hose pressure. I have a feeling I'll be referring to these forums a lot as I just ordered some supplies and food from DrFosterSmith.com to get this spring off to a little better start!
