#Grundfos scala 2 troubleshooting how to#

After taking the valves out and hooking the pump back up to the tanks, water flowed into the pump through the valve and I did not have to prime it. I still had to prime the pump by pouring water in it even though the water should have been flowing from the tank. One interesting thing, when I originally hooked the tank up to the pump no water came through intake valve on the pump. We do not have a check valve from the tank or after the pump. we shut the water off after the pump and it eliminates the cycling which leads me to think that there is a small leak somewhere. Can anyone offer any help? A few other things.

I have seen that on this forum as well, but cannot find info anywhere on the web or in the manual how to actually do that.

The manual also says to check the internal pressure of the pump and make sure it is set at 70% of the outflow pressure. We also took the valves out of the pump to make sure there were no debris keeping the valve open. We have been going through the house shutting off valves to fixtures to pin point a leaking fixture that may be causing the issue but have not found one. Now, the pump has been cycling every 3-4 minutes when water is not being used and eventually leads to a leak in the system warning light. After hooking the pump up it worked for 2 days without any issue. However, the father in law wanted to go with that pump and here we are. I did quite a bit of research prior and saw that the Scala 2 pump had mixed reviews. The scala 2 pump receives water from the bottom of the tanks and feeds the rest of the house including boiler. We just installed two 300 gallon tanks in the basement which are filled from the well with a large pressure tank (previously had that) at a rate of 1/2 gallon a minute. They have a low capacity/low recharge well they have been dealing with for 20+ years. New to the site but found some good info on here for a project I helped my father in law with last weekend.
