Accepted Answer

Possible cause: Heater non-return valve jammed. Seek service attention from an authorised service centre

Question 21

Hot tap runs fine, but the cold tap's flow is weaker

Accepted Answer

Possible cause: A kink in the cold water pipe is blocking flow. Check and re-route if necessary

Question 22

Hot tap runs fine, but the cold tap's flow is weaker

Accepted Answer

Possible cause: Blockage in the cold pipe line. Disconnect the pipes after the first Y-connector and check up to the tap

Question 23

Hot tap runs fine, but the cold tap's flow is weaker

Accepted Answer

Possible cause: Cold tap not connected. Refer to the installation instructions

Question 24

Hot tap runs fine, but the cold tap's flow is weaker

Accepted Answer

Possible cause: Cold tap failed or blocked. Disconnect and inspect

Question 25

Hot tap runs fine, but the cold tap's flow is weaker

Accepted Answer

Possible cause: A Carver Crystal water service unit's cartridge has run out, if one is fitted. Replace the cartridge

Question 26

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: Battery condition low, causing the pump to run slowly. Check the battery's state of charge

Question 27

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: Newly-fitted taps restricting flow. Disconnect and check they have a bore of at least 6.3mm

Question 28

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: Pump needs servicing. Refer to the pump's servicing instructions

Question 29

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: Pump filter or in-line filter partially blocked, if fitted. Replace the filter

Question 30

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: The pump's outlet pipe is kinked, cutting down the flow. Check and re-route if necessary

Question 31

Reduced flow from both the hot and cold taps

Accepted Answer

Possible cause: Water leak. Check all water connections

Question 32

Reduced flow from either tap

Accepted Answer

Possible cause: Y-connector(s) fitted incorrectly. Refer to the installation instructions

Question 33

Reduced flow from either tap

Accepted Answer

Possible cause: Pipe kinking restricting flow. Check and re-route if necessary

Question 34

Reduced flow from either tap

Accepted Answer

Possible cause: Bore size difference between taps. Fit taps that share the same bore size.

Question 35

Water heater pressure relief valve is venting water

Accepted Answer

Possible cause: Pressurised water system's pump switching pressure is set too high. Refer to the handbook's water supply guidance

Question 36

Water heater pressure relief valve is venting water

Accepted Answer

Possible cause: Switched-tap water system's pump flow rate is greater than the tap's flow rate capacity. Refer to the handbook's water supply guidance

Question 37

Water heater is difficult to drain

Accepted Answer

Possible cause: Hot taps not opened, preventing air entering the hot system to let the water out. Open the taps

Question 38

Water heater is difficult to drain

Accepted Answer

Possible cause: Air bleed pipe is kinked or clogged. Unkink or unblock the pipe
