How far can you run a sump pump discharge line?
Using a properly sized pipe for discharge will ensure that the sump pump will perform as the manufacturer intended. Installing discharge pipe of a larger size is not a huge problem and is in fact recommended for longer runs of pipe, typically 20 feet or more.
How big should sump pump discharge pipe be?
1.5 inches
Every sump pump has to have a discharge pipe to remove the water from the sump basin. This discharge line should be sized according to the pump manufacturer’s recommendations. Most sump pumps have a recommended discharge size of 1.5 inches. The line must be run to the outside of the house.
Does sump pump need a weep hole?
Sump pumps need Weep Holes (relief holes) in order to prevent air locking the impeller chamber. This is important because it allows air to bleed out of the interior of the pump that would normally keep the next cycles from starting. No, but why shorten the life of your pump!
How far can you run a sump pump line?
Look Outside! It is important to keep the discharge point of your sump pump as far from your foundation as possible. The minimum distance should be 10 feet. Most discharge pipes have a flexible hose tightly attached to the pipe coming from the basement.
How to calculate the sump pump discharge length?
Friction in the pipe and the fittings is also expressed as ‘head’, so you need to calculate that as well. Let’s say you will use 75′ of 1-1/2″ PVC pipe and 4 90° elbows… At TEN GPM 100′ of 1-1/2″ pipe has a bit less than 1′ head. At TWENTY GPM the same pipe has a bit less than 3′ head.
Is it OK to bury sump pump discharge line?
The buried portion of the pipe should be at least double the diameter of the rest of the discharge line. This is because the pipe underground relies on gravity to drain and needs more room to travel more slowly. Ensure the discharge exits the home in a place where the buried line can be run downhill the entire way to the exit location.
How big of a sump pump can I combine?
As far as combining pipes, a ‘general’ rule is that two pipes of the same size can go into one pipe of the next larger size, but that rule holds more true at the smaller size pipes. i.e. two 1/2 into 3/4 when you get up to the larger sizes, such as two 1-1/2 into a 2 you start to choke the flow somewhat. Install manual dont say much.
