2. PUMP NOT OPERATING
1. Has the Circuit-breaker or Safety Switch tripped off? If so, in a safe manner (
SAFETY FIRST:
do not touch the pump or water)
check that it is the pump (not something else) and if you are certain it is the pump that is causing the problem, log a ticket if it is in
warranty period, at
If out of warranty search the internet for “pump repairs in my area”
2. Is there rainwater in the rain water tank? NOTE: tank level indicators are not always accurate!! Check inside the tank to be sure
of the water level.
To be sure there is rainwater in the tank > tap the side of the tank, does it sound hollow? Feel the side of the tank, you can normally
feel a temperature difference from where the water is to where there is none. If you cannot tell that way, get a torch and look in
through the tank opening. The pump generally needs 300-400mm of water to work properly. Be sure, if you call for service and tank
is found to be empty, you will be liable for the cost of the service call.
3. Pump has an air-lock >Start and stop several times by turning the power off, wait 30 seconds, and turn on again, repeat if
necessary. NOTE: you might need to turn the Townwater supply OFF to make it easier to re-start the pump.
4. Are all pipe work valves open between tank to pump?
5. Is the pump plugged in correctly and switched on at the wall? Does the plug look wet? Isolate power at main switch, remove
plug and allow to dry. Also check power connection between pump and the pump controller is intact/pushed hard together. If the
problem continues, contact a licensed electrician.
6. Does the Rainwater have gravity feed (flooded suction) to the pump? If not, the pump will not work.
7. Check the status of the Pump Controller
–
if the FAILURE/LOW WATER light is on, it has detected no water
–
recheck the tank has
water in it, most pumps will require minimum of 300mm of water level to operate. Then re-prime it as per below and press re-set.
NOTE:
Tank level indicators are not always accurate
–
look inside the tank to be sure.
8. If all of the above are checked and pump is still not pumping you may need to re-prime the pump. Refer to the diagram on page 4,
or read on: This can be done by loosening the nut on top of the stainless steel wet end above the inlet on pump. Once you have
loosened this nut, air should come out followed by water. Tighten nut as soon as water appears. (If the TANK is EMPTY, or is BELOW
the pump, this will not work, simply turn the pump off until it rains again). Once nut is done up tight, press the reset button on the
pressure controller and hold it for a few seconds until pump runs on its own. The pump will run until all the pipe work has been
pressurized then automatically switch off. The pump will start again once line pressure drops, which occurs when a tap is turned on.
NOTE:
you might need to turn the Townwater supply OFF to make it easier to re-prime the pump.
9. For pumps drawing from an underground tank, or tank at a lower level
–
you CANNOT use the RM4000-3 with an External Pump,
use Submersible RM5000-3 Pump System (or you will have to install a PUMP SHUT-OFF CONTROLLER).
3. Pump does not run or motor runs for a short time, then stops
1. Circuit breaker or Safety Switch is off or fuse has blown > in a SAFE manner investigate why this has occurred, by process of
elimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electrician check and rectify it.
2. Water level in the tank is too low > Top up or use alternative supply > turn pump off until the tank fills
3. Electrical components have been flooded > It is likely that the pump will need to be replaced > in a SAFE manner investigate why
this has occurred, by process of elimination > do not assume it is the pump > if you cannot do this safely, have a licenced Electrician
check and rectify it.
4. Pump plug is not connected properly, or has been flooded or wet > also check the connection between the pump and the
controller to ensure it is pushed together properly > if they are OK then isolate the power at the main switch, remove plug & allow
to dry. If the problem continues, contact a licenced electrician to check the cause.
5. If all of the above are OK, the pump might have overheated and triggered the thermal overload switch > Turn it off and wait 30
minutes for it to cool down and turn it on again > If the pump does not operate normally, investigate why, it might be blocked with
debris, or the Y-Strainer/Prefilter might be blocked > flush clean and re-assemble.
4. Pump runs but does not deliver water or only a small amount of water
1. Check valve is installed backwards, arrow on valve should point in direction of flow > have the installer fix this.
2. Discharge shut-off valve/ball-valve / gate-valve may be closed > open the valve.
3. Impeller or volute openings are fully or partially clogged or it might be blocked with debris, or the Y-Strainer/Prefilter might be
blocked > flush clean and re-assemble > if it is the pump, disconnect from the power supply, and if you are competent to do so,
disassemble the pump and clean. If not, have a pump technician do it for you.
4. Pump is air-locked > Start and stop several times by turning it on and off with 20 seconds between. If this does not work, see 2.9.
