Hey PorkyPete-
Can I ask you a question?
How was it when you went to connect your 1 1/2 black plastic pipe to your inlet and outlets on the solar panels? We tried to do the samething yesterday but that black plastic pipe is so hard it wouldn't crush tight under the clamps where we connected it to the solar inlets/outlets. We are going to have to find something to make it work. Did you have that problem?

Thanks
