    Teledyne Laars natural gas EPC-II not starting

    My very old 400,000 btu pool heater is not starting this season. I took the side panel off and vacuumed out the leaves and debris. I can hear the controller powering up and trying to generate a spark for about ten seconds and then giving up. I have looked at the old heater starting threads but...

    I was looking for a larger plastic zip tie to clean the deposits from between the plates of my SWG cell. Then I spotted that plastic tool used to remove hair from a household drain. Worked perfectly!

    Blueworks BLSC 40 low salt error possible fix.

    I cleaned my salt cell yesterday and all seemed well. This morning my "Low Salt" and "Check Cell" lights were back on. After searching on YouTube I found a possible fix for a different Blueworks model with switches and a knob but I didn't see anything for this model. My chlorinator was...

    Power washer to clean salt cell plates - Yes or No? Answer: No!

    After searching the Forum I have my salt cell soaking in vinegar for the next two hours. I expect that there will be some residue.

    Teledyne Laars Series One won't start.

    Was working great. Now won't start. It is getting voltage. I'm searching the Forum and YouTube. I'm OK with checking the circuit with a multimeter and swapping out parts. It is kind of old. Suggestions appreciated. Also appreciate pointing me to helpful threads or other documents.

    Foam in the hot tub?

    The hot tub water includes the pool water. They have been circulating as one for several days. No one has been in either the pool or the hot tub for several days and the heater has been off. I started circulating just the hot tub through the heater and filter and turned on the heater about two...

    Happy robot owner. What to do with Polaris booster pump.

    So happy with my Dolphin robot! Is there something I can do with the Polaris booster pump? I don't want to remove it and deal with residual PVC circuits. Maybe a fountain or water feature for the grandchildren? Ideas?

    Jandy valve grease port replacement question.

    I was replacing the o-rings on my Jandy valves because they seemed to be leaking air. I discovered that one valve had the grease port plugged. Perhaps it broke and someone was looking for a a cheap fix. Amazon has replacements for $23. Should I replace it? What is the correct use of grease...

    Spider gasket adhesive question.

    Previous threads on spider gasket adhesive recommend this: https://www.amazon.com/Permatex-80022-Sensor-Safe-Silicone-Gasket/dp/B0002UEOKK Is everyone really waiting 24 hours before turning the pump back on? I can leave the valve in the filter position and not turn it.

    Sharing quick fix for pump leaking air.

    My pump was sucking air due to a sealing issue with the top of the basket compartment. A few turns of electrical tape worked as a temporary fix until I can get a new O-ring.

    Need advice on Nautilus 48 DE filter grid replacement.

    I have a Nautilus DE 48 (see label). I think it is fairly old. I am seeing lots of DE and dirt in the pool after backflushing and adding DE. My Polaris filters are clogging with tree droppings in five or six hours. I think that I need to replace the grids in my filter. Do I really need to take...

    Would heating the pool save palms in San Antonio, Texas?

    It is supposed to drop to single-digit temperatures for several days even in San Antonio. Our pool area has mature palms that have likely never been so cold before. I really don't want to risk losing 🥶

    I am starting a fresh thread on DIY pool valve automation. There are many historical posts involving Raspberry Pi, Node Red, Arduino, etc. I want something simpler.

    Estimating pool volume and high CYA issues.

    My new (to me) pool had an initial CYA of 100 and we all agreed to drain enough water to get the CYA closer to 50. The pool volume was rumored to be 15,000 gallons but that seemed high to me. It is a very irregularly-shaped pool that is never more than chest high. I drained out about half by...

    Northstar failing - New pump or motor or what?

    First - how do I tell which Northstar pump model I have? I'm not sure of the manufacture date because it was here when we bought the house in 06. The old pump developed a bad bearing, probably. I used a freelance pool repair guy recommended by a neighbor and he said he could replace the...

    Nice pool heater analysis program recently posted at AquaCal

    I just found this pool heater cost analysis program on the AquaCal website. I installed it and it works very well. Very detailed calculations although they seem to be tied to just a few brands of heaters. It looks like a heat pump is much cheaper than natural gas. It does pool volume...

    230 volts vs 115 volts

    I thought my pool equipment was running on 230 volts but when I measured it it was 115. What is the cost in less efficiency to run 115 instead of 230? Is is ever worth running a new 230 line out to the equipment?
