Hi,
I have solar heating which is run on the filtration plumbing. ie have to have filter pump running while solar pump is running. When I turn the solar pump on and I hear it running but it will only start to push water to the solar absorbers if I crack open the discharge union on the pump for a second or two and allow some water to come out. Any ideas what might be happening?
