Filling Loop Installation
Dimensions
Introduction
Filling loops are used to fill and pressurize heating systems using the cold
water main.
The flexible hose is a temporary fitting which should be removed after the
filling and pressurization of the heating system.
The filling loop assembly consists of the following components;
- ball isolating valve with integral double check valve and pressure gauge port.
- flexible hose with two swivel connectors.
- ball isolating valve.

Installation
If you are converting an existing system, ensure that all existing components
will cope with the higher pressures inherent in a sealed system.
The filling loop assembly should be sited on the return leg of the central
heating circuit, ideally within sight of a system pressure gauge.
If a pressure gauge is supplied fit the gauge to the double check valve
assembly in the boss provided.
Ensure the distance between the ball valve and the double check valve assembly
does not exceed the length of the flexible hose Paying due attention to
direction of flow arrows on the body of the check valve assembly, the filling
loop should be installed according to G24.1 & G24.2 of the Water Bylaws.
The double check valve assembly should be sited on the “mains side” of the
assembly and the ball valve should be sited on the “system side” of the
assembly.
The compression joints require at least 18 Nm to tighten the compression nuts
and secure the ball isolating valve and double check valve assembly into the
pipework and make water tight joints.
N.B. The flexible hose should be removed from the system after the initial
filling and commissioning when the filling loop is not in use.
If cover caps are included these should be fitted to the outlet from the
double check valve and the inlet to the ball isolating valve.
