herbie and basement sump

[SeaHorse_Fanatic]

If its air entering and no water leaking out of the union, perhaps a very, very light coat of aquarium safe silicone can seal the leak and make it more air tight. Just enough so that you can still open up the union if you need to. [I'm assuming that opening the union is not something that you will normally need to do, other than for a major plumbing project or tank tear-down]. If nothing else, it should eliminate the leaking union as a possible cause and you can check else where in your plumbing for the source of the air/noise.

you say can't get overflow silent, but where's the noise? Is it gurgling in the line below the gate valve?

With mine I placed the gate just above the sump so the drain is full of water and area around the tank is silent.

+1. Move the valve to the basement just above the sump.

but how would that work with adjusting the valve. wont making adjustments be a huge pain in the butt. always going up and down for every minor adjustment.

couple of times up and down the stairs every 6 weeks re-adjusting after opening to flush out the snail shells not a big deal. Usually though what causes need for adjustment is filter sock dirty, swap it then don't even need to touch the valve.

Seems like I've adjusted this one 100 time so far and i can't get it right

Is it salty yet? I haven't tested this yet but I've heard that Herbies can't be tuned with freshwater.

yes its gurgling right below the gate valve. but i sounds like really fine bubbles

and there seems to be a click/knocking sound once in a while.

I have a 'fuge above my sump and I get this sometimes (new sump planned - no divorced 'fuge)
In my case it's air being sucked into the standpipe
The vortec is pretty strong, even at only a couple hundred gph, and creates noises/bubbles. Clicking, thumping what have you
It's very sensitive to the level in my sump and as was stated in your case, your temp sump is probably the cause
The only way I can get rid of the gurgling/clicking/etc is to plug the standpipe with the bulb of my turkey baster until the 'fuge is quite full. The extra water height flushes all the air out and it's done - 'till I mess with a pump again and upset the sump levels
Using the bulb allows the flush without messing with the gate valve

With that said ... maybe you can still fix it with the temp sump in place
What's the water level above your main standpipe ?
Not that there's a magic #, but I'd be looking in the overflow box to see there's not a vortec happening there

There's about 5" of water over the opening . I can see that there's no air being sucked in. But I sometimes see bubbles coming out.

I'll probably end up putting a second valve closer to the sump
