The SPDKU125-24, 24' Sump Pump Discharge Kit is supplied with 24 feet of 1-1/4” corrugated hose, one 1-1/4” MPT x 1-1/4” Hose Adapter, one 1-1/2” MPT x 1-1/4” Reducing Hose Adapter & one Clamp. This universal sump pump discharge kit has been discontinued and replaced by the two new kits listed below.
Why the change?
#1 – There has been a significant increase in the number of sump pumps being manufactured with larger 1-1/2” FPT outlet connections.
#2 – Sump pump manufacturers may void the pump warranty if the discharge piping is reduced from the pump’s discharge connection size. The use of a universal sump pump
discharge kit could potentially void the pump warranty. It is important that you do not use a discharge hose that is of a smaller size than the diameter of the discharge outlet on the sump pump itself. Always follow the sump pump manufacturer’s installation instructions.
#3 – Reducing the pump discharge pipe on any pump can reduce flow, resulting in longer pump run times. This may cause increased wear on the pump, potentially resulting in premature pump failure, as well as increased power consumption.
Additional sump pump discharge hose kit information.
- Corrugated sump pump discharge hose is designed for temporary dewatering; it is the responsibility of the installer to make sure the product, and its installation meets national and local plumbing and building codes and regulations.
- Sump pump discharge hoses are designed to discharge to an open outlet which will not build up significant pressure within the hose.
- Sump pump discharge area should be 10 to 20 feet away from your house’s foundation. While some may believe that the further the better, using pipes longer than 20 feet of internal discharge piping risks overworking the sump pump’s motor capacity to push water out. Always check the pump manual for the maximum lengths of hose that the pump can handle, an excessively long hose can reduce water flow and efficiency.
- Use hose equal to or larger than the pump discharge size. Using smaller diameter hose can lead to pump and flow problems.
- Make sure there are no coils or kinks, and that the intake area is clear of debris ensuring the hose always lays out straight for optimal performance.
- Keep the hose elevation to a minimum. The higher the discharge hose goes up from the pump discharge, the less water the pump can move. Every 2.31 feet of elevation will create 1 PSI of pressure. A 10 ft. rise in the hose will create 4.33 PSI.
- Always inspect the hose for any nicks, kinks or other visible damage which could compromise the hose’s integrity / pressure holding capabilities. This is why the corrugated hose is only to be used in temporary dewatering applications, they are not intended to be used in a permanent installation, which would be in violation of plumbing and building codes in most areas.
