Repair of Wilo pump for warm floors

nem0.85xem (1) 102 2 0

It is normal practice to install an additional pump for the heating system, if there are warm floors, or when the heating circuit is large enough.
The pump in the AGV boiler may not be sufficient and a power calculation is required in each case.

In this case, a separate Wilo pump is installed for the warm floor in the area of the comb

The pump was not turned on for about two years, but the heating was working, respectively when it was turned on it was just a gull, but it was not started.

I do not have skills and experience in the heating system, but I have straight hands and tools, as the pump gags, accordingly it cannot start, we will try to disassemble.

Here by inexperience I leaked water from the whole system, although in all years it is worth updating it.

Turn the gate valve using special wrench

But a little later I raised that it is enough to close the gate valves to the waters and the outlet from the pump

From the downtime and "red" water there was an build-up in the impeller and the motor lacked the power to start the rotor.

Wash with water and twist the impeller, after a while it rotates quietly
