Hi,
I have a Stenner 45MP3 that by my calculation should pump about 2+ ozs per minute... maybe slightly more. I installed it at the beginning of this season as a chlorine pump when we remodeled the pool. Typically my filter registers ~12psi though depending on rain, dust and other factors can go higher before I backwash.
I've had trouble regulating the chlorine most of the season. I'm in the Dallas area and now in June am running the pump 30 minutes per day and still chlorine goes very low and I have to supplement. I'm perplexed!
Today I pulled and inspected the injection valve (no check valve/duckbill) which is installed downstream of the filter and in the main line headed back to the pool. There was very little buildup - pretty much an open throughput. I checked both the intake and output tubes and found the same. I pulled the suction filter thing from my chlorine tank and found it clean. The white pump tube seems in good condition and pump rotation appears functional and adequate.
Finally I disconnected the suction tube from the tank and rigged a short length into a measuring cup with water. I ran the pump one minute and it barely depleted 1/4 ounce. I then disconnected the supply tube (to the pool plumbing) and ran a short length just to open air so I could test flow without the pump pressure.. I ran the pump for one minute and voila! It depleted over two ounces. So I believe the pump is functioning okay.
Question: If my injection valve is clear and the filter pressure is only 12 psi I'm struggling to determine why I have a low flow rate when connected to the injection valve and pool plumbing. Tubes are clear, chlorine tank suction filter is clear, injection valve is clear.
If anyone has had a similar issue please let me know. Even though everything says I don't need the check valve would it help increase my flow rate?
Thanks!!
