I have to drill (5/32") out the black plastic injector every 10 days or so due to plugging with the same sort of white deposit that plagued my prior liquidator setup. The removed deposit dissolves in water acidified with Muriatic acid. Diluting the bleach with water into the Stenner from 10...

E.g. I have three cycles programmed, each later in the day, the forth is latest of all. Three cycles are enabled. I'm seeing the third not running at all despite the cycle time being needed to achieve the pool volume set. Volume:30K Three Enabled Cycles: 5:20am - 5:50am 6am - 9:50pm 11pm -...

I understand Calcium Carbonate solubility to DECREASE (unlike other salts) with increasing temperature. So I'm thinking my recent bout of WS was precipitated (pun intended) by CYA of 60, chlorine to top of LQ's white tube below funnel, CH of >350 and pH too high of near 8 AND high (100F)...

In addition to pool school:black algae teachings, I've found this works to address small patches on flat horizontal to near horizontal surfaces. Put ~1/4 trichlor puck in middle of mat with rib side of mat down. Cover area of combat with the mat. Restaurant supply stores have these cheap. Else...

I have to make some wiring changes asap inside an existing covered pool shed and am looking for feedback on conduit choices. Application is between electrical panel or Intermatic timers and pumps, a gas heater and a GFCI outlet. No wiring is LEAVING the shed, I'm just reconnecting things...

I'm hoping to get some suggestions for someone who can replace the skimmer on my pool. Suction line to pump has a blockage I can't free or successfully snake and there are some leaks around tile into skimmer (currently A&B epoxied). I'm in the Orinda/Lafayette/Moraga area of Northern...

Have 23inHg suction on my 1.5" line. It seems like I've tried everything (ha ha), but have failed so far. Have 1.5" PVC adapted up to 2" at pump inlet. First, on pump inlet side I've tried: Water hose with two sizes of "Drain Kings" run at least 20 minutes. Water hose wrapped in towel run at...

After two covers from the same vendor (they replaced 1st for free) in four months I again need a new solar cover. The bubbles in these have collapsed leaving only a narrow ridge around bubble perimeter. Cover sinks below surface and doesn't heat much. Claimed 12 mil thickness though thinner than...

I've two 30A fuses in a pullable block in the Square D, QO line, panel controlling the 240 VAC power to pool and pool sweep pumps. IS there some requirement that these STAY fuses rather than be changed to breakers? Say a 2-pole 30Amp breaker? The fuses may be time delay types. Don't remember...

For an in-ground plaster, gunite, pool is there a drop of water height from normal level for some period of time that is "very unlikely" to cause a structural problem to the pool. For example, would lowering the level 12 inches, for two days be stress free? Or maybe as a percentage of pool...

See my sig for setup. The basket isn't completely filled. I can see the horizontal "column" of water entering the basket from the inlet pipe (supply is 1.5", exit is 2"). I'm not talking bubbles like from cavitation, it's just not filled and is stable like this while running. Skimmer looks well...

I'm a new pool owner from a REO purchase so I've no historical info. Polaris 380 performance is erratic. Wheels stop turning until manually jogged. Stalls nose down. Tail often pops out of pool and sprays house and windows, etc. A pool maintenance service seems to have been working on the...
