## Questions & Answers

**Q: Will this work for producing water for saltwater tank? I am not sure if it’s same as drinking water**
A: RO membranes are filters, they separate water from solids, depending on your needs for your fish tank. That’s how finer filter you need when the membranes, new and fresh it’ll produce better water them as it gets older and plugged up so you have to test it constantly to protect your fish tank.

**Q: Where can I buy just the pink check valve?**
A: iSpring web site parts/accessories section has it. Do make sure correct fittings before placing an order.

**Q: Waste water line just dumps water even with orfice restric…What exactly is needed to hook this up after a 3 stage filter to deliver water at tap ????**
A: make a note of the quantity of water your filtration system is rated to produce per day. if your unit has an RO filter in it rated at 50gpd then you need a restrictor check valve on the waste water line going to drain rated at 50gpd. check valve needs to match output of the filtration unit and installed in the correct direction of water flow. there's an arrow on the side of them and the arrow should point towards the drain

**Q: I used the guide to hook this step by step and it just dumps out of waste water line even with a orfice that wasn’t even noted you need one ??**
A: you need a check valve on the wastewater line. it needs to match whatever the output of your RO filter is. i.e., if your RO filter is 50gpd your check valve has to be 50gpd.  just a note... checks valves are directional, check arrow on the side of check/back flow valve if you put them in wrong direction they don't operate.
