I realise that your oldest pump was made in 1945 and it still works but the question remains
Shouldn't somebody try to figure out what this pump consumes and if it is worth to replace it and what benefits would arise then?
Hi everybody.
Someone could support that pumps have a lifetime about 20-25 years.
But actually when is the right moment to change a pump?
The easy answer is when of course the wire to water efficiency gets too low.
But what if you do not use so much your pump. Are there any other theoretical...
