You will get more heat into your pool and the panels will have something to hold them in place. Its also a long term installation those panels will be there for years. Mounting them neatly on a raised surface goes a long way towards keeping everything clean and decent looking. Its your...

You should mount them on a rack if at all possible. The ground will act as a heat sink. Plywood would be best under the panels but at the cost it is today I'm not sure I would use it. As an alternative rack type system I would run your 2x6s length wise on the panel then use 1x2 strapping...

Days to a week or two is probably fine for the liner. The less time in the direct sun with no water is better but isnt the end of the world for a new liner. The pool is relatively weak with no water or backfill against it. So it's best to finish it as quickly as you can. Also the longer that...

Not my own pool but a neighbor pool was taken out by age and heavy rains. The extremely heavy (like 3inch an hour) rain overfilled the pool and likely washed out the ground under the pool. Not entirely sure what caused the failure but the rain likely played a part. Either way the pool failed...

I would read the instructions that came with the pool as to when and how much to fill the pool. As well as when and how much to back fill against the wall. It only takes a few inches of water to hold the liner in place.

You should see what older speed drives on large cranes do to power systems. Don't get me started on DC drives with Regen braking.

Industrial speed controls and variable frequency drives can play all sorts of havoc with electrical system. Sensitive electronics like GFCI devices measuring milliamp differences in current don't like even a little bit of havoc. A/C power quality can have all sorts of harmonic distortion in the...

Section 680.21 (a)(1) states at a minimum all wires feeding a pump will be insulated and not smaller than 12gauge. In addition 680.22 (a)(1) requires the addition of separately wired 15 or 20 general purpose outlet. Outside of those requirements you need to follow the other code sections as...

Spending all that time shooting to make everything perfect wasn't wasted. Its worth the effort. Pros use laser levels which saves a lot of time. I had to get a Lazer level for a septic project and I have to say it was worth every penny I spent on that thing in the time it has saved me since...

The top of the paver should be flush with the too of the foam. So yes you need to either set the pavers first then do the foam around them. Or lay the foam down and cut the pavers into it. The best way to line up the pavers is to setup the frame mark paver locations then set the pavers. Intex...

Your best best is going to be leave it alone. You would know by now if something sharp wash pushing into the liner. Just keep and eye on the depression to make sure it doesn't keep getting bigger. The more you try to play with it or inject something into the area the more likely you are to...

I would shoot for not more that 1/8" +/- difference block to block and no more than 1/4" +/- difference between the highest and lowest block. Ideally that 1/4" would be side to side or end to end difference.

Black poly has been used for decades in underground installations. Its used for well pipe all the time. I have black poly pipe run under my driveway for my well. It hasn't been crushed yet. Again each material has it purpose and intended use. Black poly is a challenge to work with in bigger...

That advice is against NEC code 680.21 (c) requires class A GFCI protection. Class A protective devices will trip at 6ma or more, they will not trip below 4ma. A class A device can trip anywhere between 4-6ma and be acceptable in design, but it must trip above 6ma.

I will echo the go with as big as you can afford and fit for the filter. An oversized filter works better and requires less maintenance. There is no way for a pool filter to be too big with residential equipment. The only mistake you can make is going too small.

Home Depot lists them as unavailable. They have the product listing but no way to buy it. https://mall.industry.siemens.com/mall/en/us/Catalog/Product/?mlfb=US2%3AQF220P

I would recommend Blue monster tape as well that stuff works really well, and one roll will last you a lifetime. https://www.homedepot.com/p/Blue-Monster-1-2-in-x-1429-in-PTFE-Thread-Seal-Tape-70885/306136345 If you use dope as well get stuff that specifically lists it for use on plastic pipe...

I am aware I have the same pump and live in your region. I run mine from the beginning of may to the end of October, 6 months. I also bring the pump inside for the winter. Your pump certainly should last longer than it seems to have but there's not much you can do to repair a faulty drive...

Make sure the cooling fan on the back of the pump is clear and not broken. Make sure the cooling fins on the side of the motor are clean and not full of crud. Is this a new pump or old? An over heating drive is generally signs you are due for a replacement sooner than later. There are no...

You got me curious about the Siemens breaker. Per their website it says product discontinued with no replacement. That QF220P is a tricky one to find. These folks claim to have some in stock. Might be with a call if you are looking...

Its the actual intended use for the product. To allow for a flexible pipe connection.

All pvc gets brittle when exposed to UV light (sunlight). It also gets brittle to the point of failure often with little to no warning. A simple light coat of paint is all that is needed to slow down that process and can buy you decades of use out of the pipe. You will notice a lot of pool...

So I think something is being lost here at a more basic level. Flexible pvc was made to meet the demands of certain applications where rigid pipe becomes a Hassel or even a hindrance. A lot of tradesmen refer to flex pipe as "spa pipe" as that is its primary application. It makes wrapping pipe...

Wasn't expecting a separate pump for solar. Right well then. I guess that changes the train of thought a bit. After thinking about a bit I'm going with a modified plan A. Leave the solar loop alone. Let it be happy doing its own thing. Definitely install the heater after the filter and...

1-6k depending on number and quantity of panels. Add more if you have a difficult or very steep roof. Similarly if you are doing a ground rack that will add cost as well.

If the pool that sat there previous was the same size and sat level for all it's years then disturb as little as possible ground wise. No need to replace the sand under the liner. Pull the sand cove back far enough into the pool to give you room to set the new wall up. You shouldn't need any...

When you say not strong enough what issues are you having? Is the pool not skimming well or are you not getting good vacuum performance. Something else you aren't happy with? You can swap pumps but if there isn't something specific you are correcting a bigger single speed pump will just use...

Welcome to TFP. Having a heater in addition to solar panels is pretty common. Most people will plumb the return line from the solar panels to the inlet of their heater. That lets the solar panels do the brunt of the work and allows the heater to pick up the slack on days the solar panels...

You can't just raise the pavers. The top of the pavers need to be level with the ground. If you raise them above ground you will be trying to lift that whole corner off the ground. The legs will not support that kind of weight. If it were me I would take it down and work to level the site. You...

Being a rectangular pool actually makes it worse to be out of level. The round pools have much better weight distribution on the frames and are more evenly supported. Long strait walls and 90 degree corners are much harder to support and put much more stress on the corners. The way I read it...
