I have a 5 year old Hayward H250FDN. It's worked flawlessly so far & my only complaint is that it's quite noisy.

I'm not familiar with any of the remote operations. All I can suggest is reading the documentation that came with those units. Sorry I couldn't be more help.

If you switch from STANDBY to POOL with the pump running does the display still show LO?

I'd remove the access panel & see if you can narrow down where the noise is coming from. Blower seems most likely.

A critter trying to escape? Something making contact with the blades of the blower? A bad bearing in the blower?

But if water on the deck makes contact with the anchors then there's still the opportunity to get shocked.

How'd to happen to notice just 1/8 inch? I'm sure you wouldn't lose it through a closed cover. With that difference in temps you'd get a lot of condensation on the bottom of the cover. Some of that condensation would roll up with the cover but probably 1/64" or less.

Here's an 'out there' idea that probably violates every code related to bonding. Put a diode between the pump & bonding wire so the wire becomes a one way street.

Do we agree that the NEV is getting to the pool via the bonding wire? Seems ironic that the bonding wire is causing the problem that its suppose to prevent.

Thanks for helping me understand all of this. Electricity is no longer as simple as I once thought! I'm not following why you think the stairs must have a connection to earth. Wouldn't you expect the voltage in the water to decrease the further you measure from the source whether there is or...

So the answer to my question is yes? If both the bonding wire at the pump & pool light ground have 5 volts & the bare bonding wire is running through the soil isn't the light ground likely to have the most voltage potential?

Let's alter this test a bit. Place the screwdriver where you can test between all four anchors & the screwdriver without having to move the screwdriver. Get readings from all the anchors with & without the bonding wire attached at the pump. The deep end anchors should also be tested with &...

Yesterday you measured 1.7 volts between the screwdriver & railing anchor. If you have time, repeat that test to confirm & check again after disconnecting the bonding wire at the pump. Also are both of those readings the same whether or not the pump is running?

I thought we were quite certain that the ground is energized. Isn't that what NEV does? Maybe I should have said earth or soil instead of ground.

Does the following theory have any merit? Let's assume the ground has 5 volts and the bonding grid is working perfectly. The bonding grid should also have 5 volts as well as the the stair railing and deep end ladder. The 5 volts is entering the pool water through the deep end ladder. The water...

Still confusing. Was the #8 connected to the screwdriver & common lead?

IIRC he was getting voltage between the deck & railing.

Hopefully it won't come to that. Here's a couple thoughts for discussion. Use a circular saw with proper abrasive blade and cut a shallow groove in the concrete next to the railing anchors. Drill & tap a hole in the top of the anchors to connect a new bonding wire to each of the anchors...

gamerfan - What are your thoughts on correcting the bonding. Sounds like you should start with the light.

I reread your 1st post & see a pump is supposed to be connected. Maybe the shop vac can't lift the water high enough.

That's what I thought but didn't think it would go in the same hole as the dry well. Strange set-up if your suppose to use a shop vac.

I've only seen a few dry wells & they had a cover that you remove then place a sump pump in the well. What is the cover that looks like it might say Hayward?

Can you post a picture of the dry well?

Very clever. For those without a jigsaw the one for the chlorine jugs can be purchased. 70mm wrench Rieke W0397

Try taking a garden hose & spray them towards the skimmer. Works well when this happens to our pool.

The screenplay has changed to 'The Case of the Missing OP' starring Ron Howard. Hope he is OK & just taking a break.

Is that actually a heat pump? What temp is it set at? What's your day time & night time ambient temps been at? How many gallons is the pool?

Also beware that if the end of the hose is below the pool level that unplugging the pump will still allow water to siphon out of the pool. Pull the pump from the water to break the siphon.

6' shouldn't matter. Make sure the impeller is clean & the hose isn't collapsing or getting kinked. Is there plenty of suction where the vac hose connects?

One of the few things we know is that the stray voltage is AC. Wouldn't the type of voltage you're talking about be DC?
