Note. There should always be some water flow through the filter, if the filter is turned off for any more than a few hours, conduct a back-wash before going back on-line. Back-wash the filter once a week when used to treat municipal mains water supplies.

Valve Manifold arrangement

If the valve manifold is provide by Dryden Aqua, the components will be provided loose for assembly on-site. PVC solvent glue, 2 brushes, sand paper, MEK clean and a cloth will be required.

It is also important to securely anchor the pipe to a wall or support from the floor. Do not hang the valve manifold from the filter. Avoid water hammer, move the laves slowly ( over 30 seconds) to allow the water flow to build gradually.
