Vaillant VCW GB 242E - replace pump after 10 years service ?
Vaillant VCW GB 242E - replace pump ?
The boiler is a good 10 years old, when installed, ended up with a
spare circulation pump . now the original pump's ran for 10 years ,
and is still working ..
Question is , would fitting the 'spare' improve anything ? I assume
the original pump cannot now be 100 p/c ..
ok if its working leave well alone .. but might as well get some use
from the 'new pump' ?
Tnx
