And we are normally worried about freezing and how to empty the case - mine all have weep holes to ensure the cases don't freeze. But in practice, I still need about 5 gallons of priming water to prime a 3" pump for a 25' suction line and 3' of lift. | |

See for example michael-smith-engineers.co.uk/products/finish-thompson/… I am not sure if I am understanding you correctly, could you please clarify? | |
