How do I program the water falls to work with the pump

It's possible that there may be an issue with the waterfall valve or a problem with the Aqualink system. Here are some steps you can try:

1. Turn off the power to the Aqualink system at the circuit breaker for a few minutes, then turn it back on. This may reset the system and fix the issue.
2. Check the valve for the waterfall feature to make sure it is closed. If it is open, try manually closing it to see if the water stops falling.
3. If the valve is closed and the water is still falling, there may be a problem with the Aqualink system itself. You may need to call a professional pool service technician to diagnose and repair the issue.

It's important to note that working with pool equipment and electrical systems can be dangerous, so if you're not comfortable with these steps or unsure of what to do, it's best to call a professional for assistance.

Thats all thats there, water pump,inlet tube,Take the cover off & pressure check the system. PS. a bad water pump doesn't have to be noisy to be faulty. the gasket,connections & water seals go bad too. Does the timing belt squeal? take off that cover & check it out. good luck

if the pump hasnt ran the o rings might b stuck ,i removed mine soeked it in hot water then hooked up a battery and pumped some water through worked fine for the rest of the season but had to do it again the next fall

Did you drain the pump in the fall? Cracked housing or blown gasket.

need thermostat or water pump going out fan in water pump slipping

Plug grunfos into any timer with 3-prong outlet.
Analog: Intermatic TN311C up to 3-on-off per day minimum 1/2 hour

Digital: Woods 50009 or 59377: 7-day programming down to minute

Generally a Grunfos without timer will operate each time water temperature inside pipe falls below 90 degrees.

So when timer turns ON, then grunfos receives power and thermostat must sense temps below 90 before pump turns on.

make certain there is a non return valve in the suction line. immediately before the pump, it can help to have a second one at the water supply
Make sure there is constant fall in the pipework , no high and low spots,
Pumps work better pushing uphill, than they work s ucking, so the closer the pump is to water supply the better
mount a pressure gauge at the pump this will help you see what is happening

Main thing: ensure that there are absolutely no air leaks in the piping from the inlet of the pump to where the pipe goes into the ground. All fittings must be tight.
Make sure there are no plugs missing on any check valve in that piping.
Put water in the pump and open a valve on top of the pump just enough to vent air, but no enough to let all the water come right out. Good Luck.

The curcuit should be simple. The pump is the heart or this system it draws water to the pump(if it can't then the hose is plugged, or damaged) or the pump is bad. If the pump is working then it should be pushing water to its destination. if the water comes out the pump but wont or cant push the water to its destination then the impeller is bad.
