    Balancing pool/spa water levels

    Set the both 3-port valves so that the SPA is totally off (handle opposite the pipe to the SPA). In that state you will likely still have a significantly waterfall spilling out of the SPA when the pump is running. Now shut down the valve on the the "SPA bypass" line until you get just a...

    Balancing pool/spa water levels

    With the valves as they are currently set in your pictures the check valves should prevent the spa draining back to the pool when the pump shuts down. So I would guess that either one of those has failed, or the pool vs spa suction valve (what you labeled inlet) does not fully close off the spa...

    Need help with wiring Intermatic timer

    I can't tell from your pictures how the on/off switch for the pump is wired, but you want to wire your SWG so that it is turn off by the switch at the same as the pump. I would guess that probably means fishing the switched leg from switch back up to the timer box and splicing it to the black...

    Trees around pool

    There are indeed lots of California natives that you could consider, we have many in our own gardens, but they are all quite messy and generally low-growing shrubs, or spreading trees. A non-native but drought-tolerant plant you might consider is Arbutus Uendo. It can be either a multi-trunk...

    Trees around pool

    I can't think of anything that isn't going to drop leaves or flowers at some point in it's life cycle. And most trees that get 10-20' tall are going to end up overhanging the pool. You might consider some of the traditional hedge plants, privet will get that tall while maintaining a fairly...

    Setting heater bypass valve

    Yes when heating you will want all the flow to go through the heater (handle pointing up in your picture). If you want to completely bypass the heater the handle would be down (pointing toward the return lines. In normal non-heating use you can leave it with the handle pointing to the right...

    Autocover vs Fence/Winter Safety over

    I'm an advocate of auto-covers. They keep the pool cleaner and warmer in addition to the significant safety benefit. However they really only work well on a pure rectangle. They can cover odd shapes with deck-mounted tracks, but that often doesn't work well. If it were me I would modify...

    Upgrade Pool Skimmer Cover ?

    I have pouralid covers for my skimmer and auto fill: https://pouralid.com/pouralid/10-round-pouralid-swimming-pool-skimmer-cover Which is same basic idea as the hide lids you link, but not quite as invisible. In particular there are finger holes to lift this out rather than the slot for a...

    Cover not closing fully - also slow to close

    The most likely cause too much friction on the ropes, either due to debris in the track or the hem were the cover material wraps around the rope is getting frayed. The other thing to check are the pulleys, particularily the the ones at the far end of the track (hopefully they are accessible)...

    ELECTRICITY in the water! What could be causing it - how to stop it?

    Glad you got it resolved! Do you have an overhead drop to your house? I ask because this happened to me years ago -- squirrels had chewed through the neutral line one the overhead drop leaving only the steel support wire to provide the neutral connection.

    Flush Spa piping diagram

    I have a flush spa with 6 jets running off a single Jandy 2.7 HP VSP, so i would expect that with properly designed plumbing, the 3HP Pentaflow should be fine as well. Someone (you or your contractor) will need to do the head loss calculations for the setup to be sure. You don't need a...

    Digital water tester

    The first time you try the drop tests have your wife (who I assume has normal color vision) observe as well. I expect that you be able to see the color changes for the TA and CH tests, and almost certainly for the FAS-DPD chlorine test (which is a transition from pink to clear). The pH test...

    Booster Pump wiring question

    If you have the proper tool for crimping them, then right-angle 1/4" connectors will make a neater looking installation, but I would probably just wrap the wires around the screw terminals, be sure to wrap the wire to that the end comes out on top in your picture (the little notch in the plastic...

    Is this "bonding" (??) wire safe?

    My first thought would be to go ahead and pull that lug off the pump, and take it to the home center to see if you can find one with capacity for two wires that will fit in the same space. Failing that would strip one or the other other of the ends a bit further back and use a split bolt...

    My heater-bypass that we installed

    The main reason for adding a heater by pass is to reduce the restriction when the heater is not in use, thereby reducing the amount of work the pump has to do to move a given volume of water. Given that as the reason there is no particular reason to cutoff the flow through the heater, just open...

    Chems/levels for SWG system

    The CYA in my pool degrades 5-10 ppm/month (and this is SoCal where we don't get any rain during the swimming season). Test monthly and replenish as needed.

    Build 101

    I would say definitely consider a Fast-lane, or Riverflow (I have the latter). That will let you do real swimming in a much smaller pool. Although the cost savings from the smaller pool will likely not make up for the incremental cost of the current generator, but the savings in space in your...

    Electrical Current in my pool - Troubleshooting Story

    It is very unlikely that the type of cable is going to make any difference in your symptoms. Assuming by "Ethernet cable" you mean the typical un-shielded Cat-5 cable (4 pairs) it is typically one notch lighter gauge (24 vs 22) and 4 pairs instead of 2, but otherwise is functionally the same. I...

    Why do most pump / plumbing installations not have covers in the USA ?

    It may be a comparable latitude to Montana, Wisconsin, etc, but per their PR site: https://www.visit-dordogne-valley.co.uk/traveller-information/Four-seasons-four-reasons/the-climate-in-the-dordogne-valley The climate looks more like coastal Northern CA vs Wisconsin.

    Why do most pump / plumbing installations not have covers in the USA ?

    Quoting our municipal code: So for me by the time we had built a block wall around the equipment it was "might as well put a roof on it as well and keep the rain off".

    Pool near detention pond?

    What is the normal water level in that pond? There's a contour line on your map marked "100 yr high water mark", have you ever seen the water get close to that after a storm? Ground water will likely be the main concern, you might consider building a partially above ground pool, elevating...

    Automatic pool cover not opening

    Does the piece you circled rotate with the shaft as you try to open or close the cover? If not likely the problem is that 1/4" roll pin that drives it has sheared (a very common problem with the Coverpools covers of this vintage. If it is rotating then it should, as you suggest, also be...

    Equipment Pad Sloped Too Much?

    I agree 1" over 3' is not unreasonable and will provide good drainage. Shim the feet on your heater to get the heater itself level. You may want to shim the pump feet as well, but that's less likely to be noticed.

    Pool temp sensor

    If you are nervous about the drilling process, make some practice holes in a scrap piece of the same sort of pipe. That will let you get a feel for the process and confirm you got the correct fit. That's what I did before drilling to find my flow meter. If you have a sharp drill bit, pvc...

    Help Me Build - All Season Pool / Greenhouse for Topicals

    Not being able to comfortably walk the entire perimeter of a pool can make it a real pain for routine things like brushing of fishing out the leaves. Looks like you currently only have the 1' coping or maybe a few inches more across the back side which is too narrow to walk (unless you are a...

    Weird electrical thing, figuring out solutions

    Assuming I've correctly followed your description that would be fine. Are you planning to relocate the SWG controller to be near the timer location as well, or leave it down under the porch?

    Weird electrical thing, figuring out solutions

    Yes your conclusion is correct. Power should come from the panel to the new switch and then to the timer which would then power both the pump and the SWG. That way SWG can not run unless there is power to the pump as well. That's how the system is currently wired, correct? As for the...

    If you are lucky they will end up in the skimmer basket, more likely they will end up on the bottom to be scoped up by your robot.

    How should I plumb my new NG Heater?

    There are dozens of equipment pad pictures on this forum, so I would say browse to see if find any good ideas. I suspect that your best bet will be to turn the filter 90 or 180 degrees and move it away from the house. What is the device on the tee between the pump and the filter? Without...

    How should I plumb my new NG Heater?

    Or consider rotating the filter 90 degrees and moving it out away from the house about 18". That will give you room to run the plumbing behind the pump. You could relocate the SWG back there as well as there will be plenty of straight pipe run.
