Inline 400 Typical Residential Installation
The Inline Pressure Boosting System is designed to increase a system's usable pressure whenever water is in use.
Shown below is a diagram of the "required" and "recommended" components of a typical pressure boosting application.

A bladder-type pressure tank is required for proper control of the Inline 400. See "Frequently Asked
Questions" section for more details. It is important that a check valve NOT be installed between
the pump and the pressure tank. Tank pre-charge pressure shall be no greater than 2 psi below pressure
setting of the outlet pressure switch & must never exceed 80 psi.
An INLET pressure gauge is recommended for the purpose of system set-up, operation, and troubleshooting.
An OUTLET pressure gauge is recommended for the purpose of system set-up, operation, and troubleshooting.
This Inline 400 will boost a downstream pressure equal to 55 psi + incoming psi. If the discharge plumbing,
fixtures, and appliances are not rated for these higher pressures, it is recommended to install a PRV after the
pressure tank to limit the max downstream pressure.
This Inline 400 will not function if the incoming water pressure is greater than 40 psi.
If the incoming supply is above 40 psi, a PRV may be installed on the inlet.
It is recommended to install a pressure relief valve in the discharge plumbing in order to protect the
downstream components from abnormal pressure spikes that may occur in certain applications.
Make certain the valves discharge is directed towards a drain appropriately sized for the
max flow of the pump system or incoming water supply.
For ease of service, it is recommended to leave a clearance of 20 inches below the pump (for housing
removal only). This can be reduced if the unit is installed with the two plumbing unions shown above.
This would make it easy to remove the entire pump from the system for servicing.

*It is recommended (where applicable) to install the Inline 400 pump in PARALLEL
with the incoming water supply. This will allow for a "service bypass" so that the
typical household can still utilize the incoming water (albeit at a reduced pressure)
if maintenance work is required. This type of installation requires a ball valve be
installed as shown above.
