10. The hot supply pipework to the pump should be a maximum length of 5 metres in 22mm
pipe (hot and cold supplies should be no more than 2 metres in 15mm pipe).
11. Exclusive hot and cold supplies to the pump with the hot from a Salamander approved
method. Exceptions, only when pump is at the base of the cylinder or within 5m, are:
• hot supply–from the vent angled at 45º, vertically down the hot connection at the vent,
at least 1.5 metres below the base of the cold water storage cistern (Figure 6).
• alternatively, the hot and cold supplies to the pump can be teed off other 22/28mm
supplies (Figure 7) provided that:
• the tee off to the pump is first call on the downward leg after the vent connection.
• the cold supply to the pump is not shared with the cold feed to the cylinder.
12. The best hot connection from the cylinder (figure 3) is either with:
a ¾ inch no stop Essex flange, or a Salamander S flange or other approved top entry flange
is fitted.
13. If pump is fitted above cylinder, a No Stop Essex flange must be used.
14. Check that water storage capacity recovery meets required flow rates, particularly at peak
demand (i.e. appliances in simultaneous use).
15. All up and over pipework must be vented at the highest point on the outlet of the pump.
16. Ensure that pipe runs minimise airlocks.
17. In positive head systems, allow for increased resistance of long pipe runs with multiple
bends. The natural flow from the shower head or other outlets must be at least
2litres/minute at all times. Any supply where the natural flow is less than 2litres/minute
is classed as a negative head situation.
