Fellow sheddies,

It's that time of year to discover that one's ancient CH pump
(UPS15-45x18) has apparently pumped its last fluid ounce of tepid lime
scale ridden sludge round the house.

Grundfos's official recommended replacement is "ALPHA2/2L 15-50" (their
capitals not mine).

plumbnation appear to have two differently priced products which as far
as I can tell are the same thing:

Product Code: 103755
Grundfos Alpha2 15/50 Domestic Circulator Bare Pump

and

Product Code: 103934
Grundfos Alpha2 L 15/50 Domestic Circulator Bare Pump
(This one is shown with the wrong picture BTW)

This leads me to questions like:

"What does the 'L' mean and is it important?"

"Are these two items really the same thing?"

"Is one merely the Google-redirected and thus cheaper version?"

Any thoughts?
