Question about Intex Automatic Salt Water System for Above Ground Saltwater Pool

Low flow My water is not clear. I have been through 3 filters in a matter of 1 and a half months. I always use my scimmer. I do my best to take care of the pool. My pool is 16' around by 48". My salt water filter keeps flashing low flow. The Low salt light and the high salt light are NOT on. I have gone over everything and I dont know why it is still saying low flow and how come my water is foggy.

If your pool has a skimmer system there is a hose from the bottom of the skimmer going to the suction port that goes through the pool wall. Disconnect the hose off of the blue adapter and unscrew the blue adapter there is a screen / strainer right there whatever gets pass the skimmer basket gets plugged up in that screen.

Another cause of low flow, and low salt warning too, is the cells inside the unit get coated with calcium. (Im in the Austin area which sits on mostly limestone.)
Its very easy to see it on the cells. My chlorine level keeps dropping as the
cell get more and more plugged up. I remove it, use the cap that came with
the pool and cap the copper end, stand it up against a wall and immerse the
cells with 5% white vinegar. It will bubble until all the calcium is dissolved,
which takes a few hours. Rinse it out and your good to go.
I have a 5000 gal pool and and run the the gererator twice a day, 4hrs.
during the hottest months (100 F) I found a Woods mod. 59377 timer which
has its own rechargeable battery backup. The GE outdoor timer wont work
unless it has a battery in it

First of all you need to buy a salt test kit that reads #'s not color
Get your salt content to 3000ppm any lower than 2800 and you will not generate enough sanitizer any thing over 3800 will set off alarms

Now that you have your salt right keep in mind an intex pump/filter is not big enough horse power for the pools they come with.

For instance with generic #'s
A pool needs to be turned over at least 3 times in a day this is bare minumum
if you have a 5000 gl pool and a 2000gl ph pump it will take 2 1/2 hours to turn it once 7 1/2 for 3 you do the math for your gallons

I run my 2500gl ph for 7000gl 24/7 and that barely does it.

I also keep 2 filters one dries while the other is in the unit
blast the used one out with a garden hose and then switch them
A dry filter works better than a wet one.
Dont ask me why, it just does
I have had the same 2 filters for this being the second season

on to low flow clean the sensor flap and put back together

Now with a clean cartridge fill the lines with water and open bleeder screws. Usuallly 1-3 depending on you model The for sure one is on top of the filter cap run filter for a minute or so then close bleeder. This should do the trick

Anoth way to help have clear water is to use a good non foaming algecide every 5-7 days and a water clarifyer to turn minute particals into larger debris that the filter can better catch

Remember even if the cartridge doesnt look dirty it really is

Again, dont be affraid to run the filter portion 24/7 it is like running a 40 watt light bulb

Best suggestion. BUY A SAND FILTER with a 1 horse motor!
Good luck

I've got the Bosch AE 9.5 tankless water heater.

1) Cheapest and most reliable solution: Install tank-type electric water heater from local box store for $250. Get store coupons, offer 10% off store price. Repairs are made same day with generic off-the-shelf parts.

2) Install grundfo water pressure boosting pump.

3) Remove areators and low flow shower heads, Maintain unit as shown in product manual: Delime tankless unit yearly, Clean water filter monthly.

4) Call city and report low pressure and report issue as fire hazard, move to different apartment. Call apartment complex and ask why they didn't read flow requirements for tankless before installing tankless.

5) Call Bosch 866-330-2729 and complain that nobody read the flow requirement or tested local water flow before installing tankless.

How do i get a higher flow into my pool

The low flow could be caused by a clogged filter. If you have a sand filter and the pressure gauge is reading a high pressure then turn the control valve to Backwash the sand filter until the water is clear in the waste pipe (usually for 2 to 3 mins). then turn the control valve to Rinse for about 1 min then turn the control valve to Filter.

Heater takes more than 1 minute to get water to kit faucet , then temp fluctuates

1) Guesses: Sounds like a bad single-handled faucet cartridge, or low water flow at faucet, or clogged water filter.
Replace faucet cartridge, clean the aerator, and/or clean sediment out of pipes below sink, and clean water filter at tankless unit each month.

2) For exact measure of problem:
Typical faucet can have 2 gallon per minute flow rate.
2 gpm flow rate means faucet fills 1 gallon container in 30 seconds. Test faucet using 1 gallon container and a cooking timer to get flow rate.
Clean aerator to improve flow rate. Compare kitchen flow rate with other faucets in home.

Most homes have 1/2" diameter pipe running to kitchen faucet.
100 feet of 1/2" diameter pipe holds 1.2 gallons of water. This assumes no sediment build-up inside pipes.

Assuming only hot is turned on: If faucet is 100 feet away from water heater, and pipe diameter is unobstructed 1/2" diameter, and faucet has 2 gallon per minute water flow, then hot water should arrive in 36 seconds.
50 feet away, and hot water should arrive in 18 seconds.

If kitchen has single handled faucet, and the handle is raised in the middle, then equal amounts of hot and cold water are drawn at same time. This doubles amount of time for hot water to arrive.

If single handle faucet has a bad cartridge, then faucet can have crossover.
Crossover means that cold water can enter the faucet even if faucet is turned to hot.
Bad single-handled faucet cartridge can delay or stop the arrival of hot water.

Tankless require maintenance including cleaning combustion parts yearly, de-lime heat exchanger frequently, and clean water filter each month.

How do I clean it?

1. remover the filter and vacume the indoor coils if they are dirty.2. after you clean the indoor coils you can take some hot soapy water and wash out the drain pan to the indoor coil and wipe any slime from the pan if possible.
3. the ourside coil can be vacumed as well . shut down the power to the unit before you proceed. You can also wash the coils with water being careful not ot get the whole thing wet but just the coils.check the air flow and wash against the direction of the air flow.
The most inportant thing you can do is keep you filters serviced. I know this is often difficult to understand but a little dirty filter is better then a clean filter.. So if it just a bit dirty it fine Ceck it monthly and if possible use a 2 inch thick pleated filter. cost more but it is the best filter for the $.
Hope this helps .. let me know .. Jon

Bosch tankless watwer heater GWH 2700 ES NG - no error codes. I have low water flow on my hot water and unit will not start? reviewed trouble shooting guide, tried everything - no solution?

The unit is plugged up with mineral buildup from the water going through it... it will need to be cleaned internally....this is done by running an acid solution through it to clean out the mineral buildup...

Then it will work again...

Oh code on a 1999 hydro spa, is it a temp sensor or what

OH is for OverHeat.
The most common causes of the overheat code are:
1. clogged or damaged pump which causes a low flow situation which in turn superheats the water moving through the heating chamber.

2. Very dirty filter which will cause low flow of water and superheat the water moving through the heater. (even if the filter looks clean, it might be clogged with small particulate matter that the eye cant see. )(to check and see if this is the problem, just make sure the hot tub is free of floating debris, and then remove the filter element. Restart the spa and see if the code comes back)

3. The last but most unlikely item would be a bad temperature sensor.

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.

Is there a filter on the back of the refrigerator that the water line hooks to? I can't remember if all of them have one or not. It sounds like either your water line is clogged or the valve feeding the line might have been turned way down. I would turn the valve off, disconnect the hose from the refrigerator and put the end in a large bowl or bottle and have someone turn the water on to see if you have good flow through the line. Best of Luck

Flo word on panel nothing else works

'Flo' means that there's insufficient flow of water through the heater, or non at all.

1) Check the water level - top up if low.
2) Ensure that all jets are open and flow water - if they don't you may have a pump issue.
3) Remove the filter(s) and see whether or not this clears the fault, if so clean or replace the filters.
