A feeder has to be certified for the specific use.Could we use the old trichlor feeder as long as we only put cla-hypo tabs in it?

Yikes! So then that would probably not be considered an exact equipment swap, so… simply installing a new tab feeder will cost us a minimum of $4,000 (for drawings and permits)! What a racket!A feeder has to be certified for the specific use.
Where in the code does it say this?considered a change in equipment which means we have to get engineer drawings and permits (required in IL for any change that is not an exact equipment swap). That adds $3,000 - $4,000 to the cost of installing the liquid chlorine feeder. Seems like nonsense to me, but that's the way it works.
You don’t want to put cal hypo in a trichlor feeder anyway. Bad stuff can happen.We have a tab chlorine feeder now that could be filled with the calcium hypochlorite tabs that Newdude mentioned above. If we switch to a liquid chlorine feeder system that is considered a change in equipment which means we have to get engineer drawings and permits (required in IL for any change that is not an exact equipment swap). That adds $3,000 - $4,000 to the cost of installing the liquid chlorine feeder. Seems like nonsense to me, but that's the way it works. The calcium hypochlorite tabs would be a way to keep CYA in check without having to change equipment. I understand that the CH will rise with the calcium hypochlorite tabs, but CH is usually on the low side in our pool, whereas CYA tends to rise pretty quickly when we use trichlor tabs. Last season I manually dosed the pool with liquid chlorine, so I'm looking for another (automated) option to keep CYA in check without spending a small fortune. I understand that trichlor and cal-hypo tabs can not be mixed in the same feeder. Could we use the old trichlor feeder as long as we only put cla-hypo tabs in it?
Section 820.100 PermitsWhere in the code does it say this?
If this is what you are told ask for the exact code section that requires an engineering drawing.
Me either.In my opinion, this is not a major alteration.
I would argue that any feeder / SWG was a comparable 'chlorine dosing system' because the output is the same.It does not include maintenance or minor repair or the replacement of equipment with comparable components.
I would be ok as long as the CYA was lower than 40 ppm.Can I use the dichlor to sanitize the pool for a brief period of time? I know it will lower pH a bit, but that is okay because it tends to run high. It will also add some CYA. Is that a problem in a bromine pool?
Thanks.... and how do I determine how much DMH is in the pool?I would be more concerned about the amount of DMH, which has the same effect on bromine as CYA has on chlorine.
Thanks again. Our indoor pool is 20,000 gals, so the amount of DMH being added per 100 lbs of bromine is much higher. What level is too high? It's not the same as CYA, is it?100 lbs of bromine tabs will add about 125 ppm of dmh to 50,000 gallons of water.
I'm doing some math here.... If regulations require bromine pools to have no more than 200 mg/l DMH and we have a 20,000 gallon pool, then we are likely above that level after using 100 lbs. of bromine to sanitize our pool.... even accounting for fill water. Is that correct? If so, does this mean we should be draining and refilling the pool after every 100 lbs. of bromine that have been put in the feeder since there is no way to measure the DMH?100 lbs of bromine tabs will add about 125 ppm of dmh to 50,000 gallons of water.
A specialized lab is probably the only way to test.Is there any way to tell if DMH is getting too high other than tracking the number of pounds of bromine tabs used?
Similar to overstabilization with CYA.What type of problems would I begin to see when DMH is too high?
It does not include maintenance or minor repair or the replacement of equipment with comparable components.
I agree... but all will depend on how an official with the state of Illinois decides to interpret the definition of "major alteration". The quick answer I got during my last phone call with a state official was that any replacement that is not identical to the original equipment will require an application from an engineer or architect. However, it's possible that I misunderstood and it will only require an application from a licensed, pre-qualified pool contractor. I will be pursuing this for sure.I would argue that any feeder / SWG was a comparable 'chlorine dosing system' because the output is the same.
