Early versions had a problem where they developed a pinhole leak around the pump housing port. Make sure no sign of any leak around pump. If have a cock near the output close this off and see if pressure can be maintained. Dismantle them and make sure they look ok. Make sure the check valves are working.I would do the same pressure for your internal and external expansion tanks and things should behave the way they are supposed to. The expansion tank pressure is measured with tap open and pump off with a tyre pressure gauge. ![]() Need to make sure expansion tank has a pressure of 70% of 3 bar = 2.1 bar. There are check valves in the inlet and out ports of the pump And I am not sure the external expansion tank will behave properly with these check valves.ĭefault pump pressure setting is 2 green lights = 3 bar. It's not usual to have an external expansion tank for the Scala2 as they have their own small internal tank. Check the pressure setting in your expansion tank.Hoping someone with more knowledge can help. Any help/ insight/suggestions are appreciated. I realize that these Scala2 pumps are garbage but it was working fine when I moved here so I didn't want to replace it. ![]() It almost seems like it's struggling to pressurize the system now even though I haven't changed anything about the setup. It's very annoying and I have no idea why it would be doing this. So for example, if I open a tap (even for 10 seconds) or flush a toilet, the pump will run to maintain the water pressure (as it should) but then it will keep on running for 5-8 minutes AFTER the water draw has stopped (tap has been shut off). Recently, however, the Scala2 booster pump seems to running for long periods of time after the water has been shut off. They also put a small expansion tank on the output line of the Scala2 booster pump for some reason (I'm not sure why as I'm new to plumbing).įor the first few months, everything seemed to work fine. The Scala2 Booster Pump draws water from the bottom of the holding tank and feeds the entire home. The well (low yield) has a trickle system into the 150gal holding tank (water goes through a 1 micron sediment filter). Recently moved into a house and this was the setup the previous owners has in their basement. Or, message all the mods and we will push your post thru.
