The impeller in the pump unit could be broken. If there is water flow into the pump, but no flow back to the pool, the impeller is most likely broken.
Make sure the hoses are not hooked up backwards.

Pump is running but not returning water to pool


If you have suction, you must have discharge. It is a law. Your water is going somewhere. Check for your water going to waste. Are you CERTAIN you have suction ? When I first read your question, I suspected a impeller with a spun out center. The motor runs but there is no pressure and no flow.

Let me know ...

Sysrem keeps saying low flow


Three areas that can cause low flow 1) the intake on the pool, if you are using the pool sweep basket feature, then undo the connection at the pool wall and you will find that the wall filter is plugs with fin bug particles that can not make it past the wall screen. Clean and replace the hose to the wall. 2) the filter is clogged and dirty, clean the filter clean the filter compartment and replace, 3) you have an air leak allowing air to enter the pump system causing air to restrict the flow of water. Check the hose connection for leakage, check to make sure the bleeder valves are not loose or over tightened, as both will cause an air leak.

Total alkalinity can be lowered by adding muriatic acid or sodium bisulfate. Acid may be added in doses of up to 1 quart per 10,000 gallons. Total alkalinity tests and further required additions of acid can be made every 2 hours.

It sounds like there was a lack of water to the reservoir, which is, I assume the inlet reservoir with the basket strainer in it.
1. Is your water level in the pool high enough to keep the reservoir full?
2. There is an o-ring or gasket on the reservoir cover, is it there and lubricated so there is no air leakage?
3. Put a garden hose into the open reservoir to see if the pump moves this water out.
Do all of this with the filter set to just go back to the pool so you can see the results.
Try this and comment back.
Good Luck,

My Rinnai is only 3 years old and just recently it has been running out of hot water for 10 to 15 minutes long intervals. We have well water and I am wondering if that has something to do with it. Kind of...


The Rinnai relys on good water flow to fire it up. In saying that it runs out of water; thats actually not possible. The Rinnai just heats up water as it goes. Usually faults for installs on bore or well water is a problem with water flow. Causes are blocked filters or your water pump from the bore starting to fail. I would expect you to have a large filter somewhere on the water line from the well. Try and find it and clean it out. The Rinnai also has a filter. Its like a plastic round shaped nut just under the heater on the middle connection. Turn the water off first, it should almost unscrew by hand, take it out and clean it (make sure you don't drop the O ring on it). Also some tapware have water filters right in the end of the spout, check these too. After you tried all this focus on the pump. Make sure no ther water is flowing, try the hot tap and see if it works. Do the same but slowly turn on a cold tap, slowly increasing the flow. Have someone out by the heater and see if the heater shuts down at any point. If it does it could be the water pump at fault. From what you have told me and I am certain water flow is the culprit here. Really focus on anything that might lessen the flow before you start messing with the heater. Best of luck.

It says low flow, how can i fix it. its a Intex Automatic Salt Water System for Above Ground Saltwater Pool


After five years of using our pool each summer, we assembled it last week and I kept getting the "low flow" warning (with irritating beeping) even though the water flow was very good. I disassembled the unit and checked the flow switch, and found that the switch itself was the culprit. Here's what I did: (this is probably not recommended by Intex...) I unscrewed the main portion of the salt water purifier (the part with the digital display on top) from the base and lifted it up to expose the circuit board and wiring. All the fuses were intact and everything looked good. At the bottom of the circuit board, about an inch from the right edge is where I found the connections for the flow sensor. One was marked "flow" and the other was "grnd". I removed the plugs that run to the slow switch, closed the circuit by making a direct connection between the two plugs, and voila! No problem. I ended up cutting the wires about 1-1/2 inch from the plugs and connecting them with a wire nut, then I plugged them back in. The unit is working perfectly again.

If you attempt this, make sure the unit is unplugged and be careful when dealing with the circuit board. Don't be intimidated, it's not a high-voltage connection you are working with, you are simply closing the circuit and telling the board that the switch is closed as it would be with adequate water flow. I was comfortable making this "modification" and bypassing the flow sensor because we have several years of experience with our pool and because I clean and swap out our pump filter every day during summer, and because we know the difference between strong and weak flow just by checking the inlet and outlet ports in the pool.

I hope this helps someone! It took care of my problem. Best of luck.

My new ec50 is clogging frequently. Is at 18 psi


lower the better (psi) this means the water is flowing fast through the filter, high pressures means it's time to clean filter again. keep cleaning until the pool is squeaky clean, then you can go back to cleaning once a week

How to open pool, fill sand filter with water?


I happen to have a copy of the users manual for this pool filter. These are the instructions for operating your filter.

1. Be sure correct amount of filter sand media is in tank and
that all connections have been made and are secure.
2. Depress Vari-Flo control valve handle and rotate to
BACKWASH* position. (To prevent damage to control valve
seal, always depress handle before turning.)
3. Prime and start pump according to pump instructions (be
sure all suction and return lines are open), allowing the filter
tank to fill with water.
WARNING: ALL SUCTION AND
DISCHARGE VALVES MUST BE OPEN WHEN
STARTING THE SYSTEM. FAILURE TO DO
SO COULD CAUSE SEVERE PERSONAL
INJURY.
Once water flow is steady out the waste line, run the pump for
at least 2 minutes. The initial back-washing of the filter is
recommended to remove any impurities or fine sand particles
in the sand media.
4. Turn pump off and set valve to RINSE position. Start pump
and operate until water in sight glass is clear—about 1/2 to 1
minute. Turn pump off, set valve to FILTER position and
restart pump. Your filter is now operating in the normal filter
mode, filtering particles from the pool water.
5. Adjust pool suction and return valves to achieve desired
flow. Check system and filter for water leaks and tighten
connections, bolts, nuts, as required.
6. Note the initial pressure gauge reading when the filter is
clean. (It will vary from pool to pool depending upon the
pump and general piping system). As the filter removes dirt
and impurities from the pool water, the accumulation in the
filter will cause the pressure to rise and flow to diminish.
When the pressure gauge reading is 8-10 PSI (0.55-0.69
BAR) higher than the initial "clean" pressure you noted, it is
time to backwash (clean) the filter (see BACKWASH under
Filter Control Valve Functions.)

I have an kenmore elite with error code f02???


The drain pump has either failed or the pump filter has become clogged.
To check the pump, remove the bottom access panel. There you will find access to the pump clean-out.(Large,white screw cap).

Unscrew the pump clean-out, catching and discarding the water. When the water flow finally stops, completely remove the clean-out filter. Inspect the clean-out filter, the drain hose from the tub as well as inside the pump impeller for any additional debris.
