  • Product Description:

    Salamander 22mm S-flange - 1" x 22mm. Brass construction.

    When installing a shower pump, it’s important to make sure there is no air in the system, as this can cause damage to the pump. To help with this, our guidelines state that you fit a flange during installation.

    Salamander 22mm top entry compression fitting S-flange. The Salamander S-flange encourages aeration to follow a natural path to the vent and prevents aerated supply water being drawn into the pump.

    What is a flange?

    A flange is a device that limits the amount of air entering a pump from the hot water cylinder. When water is heated, or replaced within the hot water cylinder, air bubbles are formed and collect around the side or the top of the cylinder. The bubbles then rise up to the top of the  vent and expansion pipe (figure 1). By installing a flange, these air bubbles are prevented from entering the pump, as the flange is able to draw water from deeper within the hot water cylinder.

    Aerated water supplies to pumps, showers and other outlets means:

    • Unnecessary, perhaps sudden temperature fluctuation at the shower or other outlets.
    • A noisy pump.
    • Accelerated degradation of the pump's mechanical shaft seals eventually to leak. Premature pump breakdown.
    • A correctly fitted Approved Cylinder flange will mitigate if not prevent these risks.
    • A quiet life and peace of mind for the customer.
    • An easier life for plumbers.

    Some Salamander Pumps’ products require a flange to ensure a valid warranty. Salamander Pumps’ CT range does not necessarily need a flange, provided that the pump is installed at the base of the hot water cylinder, the cold-water tank is higher than 1.2m above the cylinder, and the pump is ‘teed’ off the first downward leg from the cylinder.

    In general, best practice for all pumps is to fit an anti-aeration flange to the hot water cylinder, so that a dedicated supply feed can connect the flange directly to the hot inlet on the pump (Figure 3).

    • Great service and pricing from NSS. This is a substantial product that gives peace of mind when using a pump. Only point to note is that this is designed for a 1" BSP tank outlet. Mine had only 3/4" connection so I had to get a brass reducer and then apply some care to get it all to fit.

      Andrew Richards

    • Good bit of kit. Includes adaptors for 28mm vent as well as 22mm.

    • I've not installed this yet and therefore can only comment on the service I have received so far. Very good service and excellent communication via email from initial ordering through to delivery.

      Robert Briggs

    • Absolutely necessary for shower pump installation, great kit supplied with this including a convertor for use on a male tank outlet which I needed. Required the use of jointing compound to seal correctly.
