Question 1

can i hook up my ispring ro system to hot water to make it work faster?

Accepted Answer

No. The system is not designed for hot water. Operating water temperature range: 40–100 °F (4–37 °C). Consequences: Hot water will damage the RO membrane and plastic components. Correct practice: Connect only to a cold water line. Warmer water within the specified range will increase production speed, but do not exceed 100°F.

Question 2

ispring ro faucet is just a slow trickle even though the tank should be full, how do i get more pressure?

Accepted Answer

A few things can cause that trickle. Let's start with the most common. First, confirm the tank is actually full. It takes 1.5 to 2.5 hours to fill from empty. If you just installed it or ran the tank dry, you need to wait. If the tank is full, your incoming water pressure might be too low. The system needs at least 45 PSI to work correctly. Below that, flow will always be slow. You'd need a booster pump. Also, check for a crimped or kinked tubing somewhere between the tank and the faucet. Even a small kink can restrict flow dramatically. Follow the blue tubing from the faucet back to the system and straighten any bends. IF THAT DIDN'T WORK: The tank's internal air pressure might be low, but that's less common on a new system. The main suspects are tank fill status and incoming water pressure.

Question 3

installed my ispring tank valve but it's leaking at the threads, i used teflon tape, what did i miss?

Accepted Answer

You didn't use enough Teflon tape, or you wrapped it backwards. The seal is insufficient. Shut off the water supply to the system. Unscrew the tank valve. Clean the tank's metal threads. Apply new Teflon tape. Wrap it clockwise (looking from above) around the threads 8 to 10 times. Do not skimp. Screw the tank valve back on clockwise and tighten by hand. Do not overtighten with a tool. IF THAT DIDN'T WORK: If it still leaks with proper tape application, the valve itself may be defective. Contact iSpring Customer Support for an immediate replacement.

Question 4

water from my new ispring faucet is cloudy or has bubbles, is it safe to drink?

Accepted Answer

Cloudy water with bubbles is normal after installation or filter changes. Cause: Trapped air in the system. Resolution:The bubbles are harmless and will clear on their own. They will disappear as the system flushes out the trapped air over several days. No action is required. The water is safe. Note: This is distinct from black water, which can occur when flushing new carbon filters. That should also clear with flushing.

Question 5

my ispring t32m drain line keeps running non-stop, even overnight. is it supposed to do that?

Accepted Answer

Yeah, this one's common. It's not supposed to run continuously. It usually means the system can't build enough pressure to shut itself off. The top suspect is low incoming water pressure. If your home's PSI is below the required 45, the system just can't fill the tank and trigger the shut-off. You'll need a booster pump. If your pressure is good, the Automatic Shut-Off Valve or the check valve might be defective. Here's a quick test:Get some water out of the RO faucet first, so the drain is actively flowing. Close the blue valve on top of the storage tank. Wait about five minutes, then check the drain line. If it's stopped flowing, your valves are probably fine and the issue is pressure. If it's still flowing, you've got a bad valve. Open everything back up, let the tank fill, then close the feed water adapter to cut the supply. Wait 15-30 minutes. If the tank empties, the check valve is the culprit. HEADS UP: During the initial 1-3 hour tank fill, the drain will trickle. That's normal. It's the 4+ hour marathon runs that are the problem.

Question 6

ispring ro water tastes just like my regular tap water, did i do something wrong during install?

Accepted Answer

Yes, the RO membrane is likely not filtering. Either it's not installed, or water is bypassing it due to a connection error. Immediate check: Open the stage 4 membrane housing. The blue RO membrane must be inside. If the housing is empty, install it now. Verify all tubing connections. One wrong connection can send tap water straight to the faucet. Test the TDS. Your tap water TDS and RO water TDS should not be the same. The system should reject over 90% of TDS. If they're similar, the membrane isn't working. IF THAT DIDN'T WORK: If you get some TDS reduction but not 90%, water might be bypassing the membrane due to a faulty Automatic Shut-Off Valve or a bad membrane itself. You'll need to contact iSpring support to pinpoint it.

Question 7

just installed my ispring ro system and there's a leak where one of the plastic tubes goes into a fitting, how do i fix this?

Accepted Answer

That leak means the tube isn't sealed inside the quick-connect fitting. You need to push it in past a small rubber O-ring inside. First, remove the blue lock clip from the leaking fitting. You can use your fingernail. Pull the tube out completely. Check the end of the tube. It needs to be cut square and clean. Measure and mark 5/8 inch from the end of the tube. Now, re-insert the tube into the fitting. Push firmly until you feel it pass a point of resistance—that's the O-ring. Keep pushing until your 5/8-inch mark reaches the fitting. Pop the blue lock clip back on. That locks it. IF THAT DIDN'T WORK: The O-ring inside the elbow fitting itself might be bad. Unscrew that elbow fitting and replace it with one of the spares from the kit. Wrap the new fitting's threads with Teflon tape before screwing it in. HEADS UP: Check for leaks daily for the first two weeks. Use the included flood alarm for extra safety.

Question 8

my ispring t32m tank is taking forever to fill, like hours and it's still not full, what's going on?

Accepted Answer

Your incoming water pressure is likely below the 45 PSI minimum. That pressure isn't strong enough to push water through the RO membrane efficiently. The system drains continuously and the tank never fills. Check your home's water pressure. If it's below 45 PSI, you need to install a booster pump. Verify the Tank Shut-off Valve is ON. The valve handle should be in line with the yellow tubing. Double-check all tubing connections. A single incorrect hookup can stop flow. IF THAT DIDN'T WORK: The Automatic Shut-Off Valve or check valve could be defective. To test, fill a few glasses from the RO faucet, then close the blue valve on top of the tank. Wait five minutes. If the drain line is still flowing, one of those valves is faulty. HEADS UP: Normal fill time is 1.5 to 2.5 hours. It's slower with cold water (below 40°F), high TDS (over 750 ppm), or low PSI.
