Pinhole in pressure tank

[Brian94]

Lubricating the thread helps. Stainless steel threads have a nasty habit of galling if dry.

Thank you I will retry my connection and update.

Beautiful job! Just loosen all the way on the small adjustment in the pressure switch to get the minimum delta between on and off. If that Square D switch doesn't adjust like it should just let me know.

I did loosen it the whole way out to where the spring flopped around, which should have given it the minimum as stated. Then again I should have just bought a new pressure switch from you, since I'm reusing my old one. It's a home desperate everbilt switch. It did have some rust sediment in it that I tried to clean out. I'm assuming there could still be a little more stuck in there creating issues with the diaphragm. Probably better off just buying new switch?

I had the same problem where sediment/mineral encrustation built up under the diaphragm causing the cut-in to be lowered. IMHO they are not worth the effort to rebuilt. Just replace it. Resist the urge to get one with the low cutoff option. They are just a nuisance.

Will do I'll pick up a ole reliable square d tomorrow, then dope my union nut, knock it all out at same time with tank drained. Painted my well casing at least.

Update was able to reseal my union. I applied anti seize on union thread and gave it a good crank with pipe wrench, appears to be sealing good. While union was apart I was able to pull well seal off and check and re torque the band clamps on drop pipe.

Replaced my old pressure switch with square d. Had first start up it was 38-58 was able to adjust it up to 40-60. Amazing how lowes wants sells 40-60 for 5$ more than 20-40. When one can adjust it to whatever they desire.

Probably over observing, but this pressure tank seems pretty noisy hearing the bladder expand, then again I didn't pay much attention to the old big blue one.

Here's picture of my old switch. Quite a bit of rust, crazy to think that could be from my old galv nippe, coupling, and ell? Its interesting that the switches seem to have an integrated snubber on them.

I suspect each factory preset pressure range, utilizes a different spring with a slightly different tension. That should ensure the pressure adjustment nut will be roughly centered within the intended adjustment range when it leaves the factory, with no springs being either over compressed or too slack.

Actually I think it is the same spring on all Square D FSG2 switches. It will adjust from 20/40 to as high as 55/75.
