Hi all.
I have a vailant ecotec 831 r1 boiler, the pump is starting to get a bit noisy, I have a gas safe friend that will fit a replacement for me,
I know I need a 178983 pump for my type of boiler, but I have noticed the words ( Type VPal - 7/2a ) on some pumps & ( Type VPal - 5/2a) on other,
Does anyone know what these figures mean, as both pumps are advertised to fit my boiler, both 5 wire to replace original 3 wire old pump.
Cheers for any I for, pete
