Rainman,
Is this the type of whole house filter housing you were talking about?

As far as the Gast Roc-R pump, this is the spec sheet for their pumps. Which model do you have?

I'm also wondering if the diaphragm pumps would work because there are a lot of models that are DC, and I don't have electricity to the pond dam.

I'm also curious of the attachments used. I'm assuming that their is some type of connector on the whole house filter that attaches to the tire valve. Then a tube or pipe connects the filter to the pump. Is this correct?

Thanks for the input.

I started with nothing, and still have most of it.
