Re: Pool pumps

Not a problem. At least I know where I'm located. lol And I think I can find what I'm looking for by searching my posts. I'm also reading on centrifugal pumps, specifically the ones that were installed so at this point I can find my way from the balance tank to the filter basket and on to my pumps and why it is all set as it is. Suction piping! Discharge piping! Gate valves! Foot valves! Pressure gauges! And I found Pump Ed 101. I have some reading to do. I'll try harder not to be annoying. lol It's embarrassing to be a newbie. :oops:

Thanks for your patience!

Is this a commercial pool?
Yes it is...I have merged the threads.
 
Huh. I've inherited the entire school to take care of. lol But the pool has taken up most of my time. Mixing up a 100 gallon vat of muratic acid (sp) takes awhile.. Back to my first testing, where my FC level was 1.5 ppm, I watched the testing of performed by the long gone pool operator and seen that his FC test were at 2...no problem and I didn't bother checking until went down to take over his responsibilities after he left and seen that he didn't bother testing the pool that last week.

So I did it. The FC was at .5 ppm. YIKES! Turns out there was a chlorine leak and with two people working on the problem they shut off the chlorine lines located waaaaay over behind the sand filtering pigs. Plugged in the manual pump to help bring up the chlorine level and by the p.m., it was registering 2 ppm. I'll test it all this a.m. when I go in and see what's cooking. Yeah, it'll be in our best interest to slam the pool yet it's never empty of people. How long do you suppose that pool will have to be closed to do a thorough job?
 
What is the typical bather load on this pool?

It's very hard to say how long a SLAM will take, but it does appear that it needs doing.

Since you have zero ppm CYA your SLAM level is about 5 ppm.

How is the pool normally chlorinated?
Are there regulations in your locality prohibiting CYA in the pool?
 
Thank you, Bama Rambler.

It's registered at 334 but daily no more than 100 swimmers, Saturday maybe 50 but competitive swimmers are all I have at the moment. I'm lucky that Physical Ed. classes haven't started yet because that will pump it up to 160+, daily. The weekend of the 10/4 & 10/5 will see 200 + swimmers in competition. Sundays are quiet.

The pool is automatically chlorinated through Chemtrol although I do have a manual pump.

This a.m. the pool was still registering at 2 ppm FC and the pH was at 7.6. What I didn't like was that my chlorine pump wasn't running nor the acid. Maintenance said it's not unusual for the pumps not to run. I've never been down there that they weren't running. People are using the pool. I'm advised to wait until the chlorine level falls again before doing anything. So I brought the Chemtrol manual home so I can "set the standard". I think it's called calibration. lol

I'll have to check the regs on CYA, I might even have it here....somewhere. Sheesh, paperwork, paperwork.

If the pump is sized correctly it should shut down periodically in low bather load scenarios. It should be sized to handle larger than the maximum bather load for the pool.

I assume you have the ORP sensor and not the direct FC sensor?

Thanks, Bama Rambler. I believe it is an ORP sensor. And there is another sensor for acid. I left the manual in my car (I just got off work....I'm not ready to go back to work) It's the 1st line on the Chemtrol that maintenance says is to be read as chlorine. lol It is adjustable. Let me read some. My brain is spinning from pumps, boilers, boosters, air handlers and the Dectron. Yikes!

I'm wondering about the size because I have a manual pump to help boost the addition of chlorine into the pool. It came in handy but that was a different scenario altogether. I'm just paranoid because the chlorine went down in the first place. Now that I know where the additional shutoff is, I can check it first thing when something is amiss.

I took my camera with me today to take some pictures but no time. Maybe I'll wander in and take additional readings and a few pictures because you've got me wondering.

Thanks for taking the time.

Huh. Although I wanted to slam the pool for equipment failure, the .5 ppm fell within tolerance. What is considered normal operating range is 0.4 - 2.0 ppm, FC. Limited Contamination, i.e. fecal, blood or vomitous material would have been another matter. Those numbers were taken from the Pool Contingency & Emergency Response Plan. Thanks to my supervisor for supplying me with the important stuff.

And thanks to Troublefreepool for defining FC, TC & CC. Slow but sure.

And thanks to my folks who taught me that if you're not sleeping, get to work. LOL
