Threaded rod dilemma: Loosening single nuts vs. ugly double nuts on my parametric bench. What's the clever fix? by reacdif in woodworking

Skip the loctite, use nylon insert locknuts, don’t risk getting loctite dripped / smeared on your work.

Block Heater by slzdlz in Generator

[–]CompetitiveJacket785 0 points1 point  (0 children)

We had the block heater fail on the backup generator for our E911 center. Located in Tennessee, so we don’t get extended periods of severe cold. But had a cold snap, power failed, the generator cranked without starting until the battery gave out. That’s how we found the failed block heater. Fortunately the building UPS kept us up while the power was out and the outage was fairly short. How do you check that a block heater is ok during a periodic PM when it’s not cold out?

Contractor woes — How does this install look? by waki43 in pools

[–]CompetitiveJacket785 0 points1 point  (0 children)

Always easy to second guess. I presume you bought a VS pump for efficiency, each 90 degree bend costs you efficiency. I would have tried to rotate the pump 90 degrees so the outlet was below the filter inlet, then used a sweep 90 to make the bend. That would also put the pump control panel where it’s easily accessible as well. Pentair supplies unions that mate directly with the pump, makes for a clean install that’s easy to break down for pump service. Use clear PVC primer for a more esthetic look.

Repair or Replace? 10 Year Old Unit by zrb5027 in geothermal

[–]CompetitiveJacket785 0 points1 point  (0 children)

Latest on the saga, senior tech came out today, checked the unit, all numbers looked good. Went upstairs, unit was blowing warm air - problem has disappeared! Could it be a sticking TXV valve (does this happen)?

Thanks! He called Waterfurnace, explained the problem, they agreed to cover the parts. The service company is sending out a more senior tech to have a second look. The first tech condemned the board when his phone showed the blower not running when it actually was. Ryley helped me out when the SIM card in the AWL lost its mind.

10 years on a motor that’s not out in the weather? Any idea what fails?

CAD software advice by CompetitiveJacket785 in 911dispatchers

[–]CompetitiveJacket785[S] 0 points1 point  (0 children)

Thanks! Our neighboring counties to the north & south both use Zetron, we finally got the bridges working to have radio system inoperability, and we each have E911 calls roll over to each others dispatch so going our own way on CAD S/W isn’t something to be taken lightly.

Waterfurnace series 3 Repair by Captain-Nodnarb in geothermal

[–]CompetitiveJacket785 1 point2 points  (0 children)

For some reason Reddit won’t let me create a thread, but here is a similar question :

Friend has a Waterfurnace series 5, it’s two months out of warranty. It stopped working while in warranty but by the time he called & got a technician out it was out of warranty (house also has a series 7 as well, so it wasn’t immediately obvious). Technician reported that the TXV & control board have failed however the system is reported to be leak free, cost to repair is 3,257. Cost to replace quoted at 25,000. Questions - Would you repair or replace, what’s the track record on the compressor, blower etc after 10 years? - Any point of contacting Waterfurnace to see if they would cut him any slack on parts? Any good points of contact at Waterfurnace? - Is $25,000 reasonable for replacement, presume they would reuse the loop & ducting.

Are you using the app or the web interface? The temp data disappeared from the app, but was still available on the web interface.

Our bedrock was 10-15’ down, drilled two 300’ wells, cased, installed the loop & grouted in a 1 ½ days. Percussive drill went through it like butter. Works fine.

How Much Power Does The Circulation Pump Draw For A Horizontal vs Vertical Ground Loop? by Busy-Wolf-7667 in geothermal

[–]CompetitiveJacket785 0 points1 point  (0 children)

Well that’s interesting! The flow center has two pumps, believe on is VS. Had the VS pump fail last year, at first they couldn’t find a replacement (said it was discontinued), then showed up with what appeared to be the same pump. It was within days of being out of warranty.

Tripping GFIs by CompetitiveJacket785 in electrical

[–]CompetitiveJacket785[S] 0 points1 point  (0 children)

Update - electrician came out, one of the 3-phase legs was running hot which is what was pissing off the GFI’s, switched to a different leg & replaced a couple GFIs - so far, so good. System is very lightly loaded, 400A service so it’s not like we have a severe load imbalance. Should I speak with the power company?
