jkusmier Posted August 9, 2013 Report Share Posted August 9, 2013 I'm sure it's highly variable, but how long until it fails? 2 weeks? Longer? I found a new one for ~$400. I'm fairly handy - is this something I can wire myself? Do I need any special tools? Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted August 9, 2013 Report Share Posted August 9, 2013 Run it till it dies, or your neighbor calls, whichever is first. You wont wreck anything by letting it run, cept maybe your hearing. Quote Link to comment Share on other sites More sharing options...
jkusmier Posted August 11, 2013 Author Report Share Posted August 11, 2013 Thanks, Pool Clown. It's intermittent, but she's singing more and more. I ordered an identical replacement for an outstanding price from a reputable online retailer, and picked up some new Southwire conduit and fittings today. I'll probably switch it out as soon as I find the time - which may be before it fails - because my schedule is pretty hectic right now. Do you foresee any problems using the existing unions for a couple of months, and then installing the new unions later, probably at closing? Thanks as always, I appreciate your advice.

Dr. Spa Posted August 11, 2013 Report Share Posted August 11, 2013 Existing unions, new O rings, and your done till next time. Quote Link to comment Share on other sites More sharing options...
jkusmier Posted August 12, 2013 Author Report Share Posted August 12, 2013 One last question: the pump is actually a 1.5HP Pentair SuperFlo - I mistakenly described it as a WhisperFlo). Just ordered the identical pump as a replacement, I'm wondering if I should change order to a 1HP? ~17,500 Gallon inground Plumbing is all 1.5" Equipment pad is roughly 20' from pool and at same elevation 2 intakes (1 skimmer + main drains) 7 returns (3 on side, 2 in step section + 2 laminar jets that I use only occasionally, but when I do I like them to fly high) Pentair Sand Dollar SD80 (3.5 sq ft filtering area, 50PSI max (consistently reads 20PSI w/ existing 1.5HP pump), 75GPM max flow rate Pump flow rates are ~90 for 1HP, ~100 for 1.5HP. As always, I'm very thankful your advice. Quote Link to comment Share on other sites More sharing options...
Pool Clown Posted August 14, 2013 Report Share Posted August 14, 2013 Why did you buy a new pump when all you needed was a motor? Quote Link to comment Share on other sites More sharing options...
jkusmier Posted August 14, 2013 Author Report Share Posted August 14, 2013 I asked myself that, but I found a new pump at a price only $70 more than the cheapest replacement motor I could find. Also, there are a gaps between the seal plate and the volute on the top and one side, like something is warped. Quote Link to comment Share on other sites More sharing options...
jkusmier Posted August 18, 2013 Author Report Share Posted August 18, 2013 BTW, I ultimately found the replacement at far less than $400. Installed yesterday in less than an hour. I like the new plastic motor canopy/cover. Also like not hearing my pump! Quote Link to comment Share on other sites More sharing options...
Bugman1400 Posted August 20, 2013 Report Share Posted August 20, 2013 Why wouldn't you just replace the bearings for $20? The only special tools you need is a workbench and your brain. Quote Link to comment Share on other sites More sharing options...
jkusmier Posted August 23, 2013 Author Report Share Posted August 23, 2013 You forgot to mention a bearing puller. Actually, I didn't consider trying it myself until I watched a few videos - after I'd installed the new pump. So maybe I'm just short one brain.
