Appreciate your help. Water temp is 50degF. I'll try to ck FC level tomorrow. Don't have means to ck CYA level.

Actually I have it serviced every Wed so don't have any chems at hand. Travel a lot, so tough for me to manage pool. I do have a test kit, but no chlorine. Trying to get a sense of how long I can shut down circulation before needing to treat pool? Realize it's an estimate. Is 2-3 days too long?

Last couple days have noticed wet spot near a decking drain. Been raining a bit, so didn't think much of it. Went out today in sunshine, area was dry. Ran the circ pump, water appeared, so apparent leak on pressure line to pool. Worried about water damage, can I leave the circ pump off for a...

Removing the bonding wire from the subpanel will not isolate the equipotential grid from service ground. Electrically, the bonding grid will likely still be grounded via a pump/heater bonding lug and EGC. The bonding discussion above is a good one, however, to mitigate the occurrence of...

I don't disagree with the ineffectiveness of this bonding grid beyond the pool pad equipment. To achieve NEC bonding grid nirvana, I would need to cut a trench around the pool cool decking, lay a copper bonding wire, tie it to the light nitch (another circuit in another panel), trench the...

Re: Equipotential bonding grid & ground rod I guess they use a lot of double insulated pumps and what to do about the heater & blower? After sifting though all this, my plan is to uninsulated 8awg copper bond the 2 pumps, heater, and blower, remove the direct bond to ground rod...

You nailed this. Interpretation of this Fine Print Note is what I've been struggling with...precisely because of what danpik notes in his followup... that the bonding grid is indirectly connected to ground (and a ground rod if appropriate) via the pump/heater bonding lug and EGC. How is this...

New owner, older pool (circa 1980s). There is a grounding rod near my pool equipment pad. It is currently connected to the equipotential bonding grid (couple pumps, blower, heater). As far as I can tell this grid only includes the pool equipment and not the pool structure. As I understand...

I have some shrubbery in the way, we're clearing that out so I can look around the pad. As noted, the only candidates I've seen so far are 2 pieces of rebar that extend up through the pad for no obvious reason. As to candidates, how would one determine that a copper wire/rebar/whathaveyou is...

Best I can figure it was built between 1980-84. The pool is surrounded by at least 5-10ft of decking, which extends to an adobe wall, so a retrofit bonding project would be major work. There are a couple rebar rods which extend through the top of the pad, nothing attached to them. Perhaps...

The pool has no diving board or metal rails. I don't see any bonding provision around the pool. How would I bond the pad equipment to the pool structure?

Thx for reply. I'll replace the green wire. Just to confirm, the #8 bare solid copper bonding wire should connect the 2 pumps, blower, heater, and control panel? The DE6000 filter doesn't have a bonding lug...does it need to be bonded?

New home/pool owner, in the process of converting older mech timer system to Intermatic 653RC. There are 2 pumps (circ and spa), blower, and heater, all 240v. There is a bonding wire among the 2 pumps and the heater attached to a grounding rod next to the pad. There is no bonding wire to...

Nice layout, thx for response. Any other options?

Recent home buy, first pool/spa. I'm having the pool professionally maintained (good company) while I deal with equipment/pad issues. The spa heater, pump, and blower are energized by a spa control switchbox located a couple feet from the Intermatic control panel and mounted on a dilapidated...

We've always wanted one, so recent move afforded the opportunity. New residence in North San Diego county, 4 acres of avocado trees, shared with my wife, mom, and 2 Boxers. Pool is approx 21000 gal with spa, pebble-tec'd about 5yrs ago. Having it professionally maintained while I learn about...
