Please bear in mind that many of the builders that frequent this board are busy building. They will probably respond but it will take some time. Many of the people that post here also post at TFP too, myself included. If your pool is already walled, backfilled and decked, the fact that you have a Hayward light niche and sand filter already pretty much makes the continuance of the Hayward equipment for the sake of continuity and integration a simpler path. The additional warranty is a bonus as is the fact that it will likely cost you less. I hope you weren't stung too badly by the PB's actions that lead to his conviction. If the pool has not been decked yet, it may be possible to change the niche but I don't know if the the mounting holes will line up. I have never had to replace a niche. Adding an addition hole for another niche with a steel walled pool might require an replacement wall panel. That will likely cost you a liner too. The additional fixture and niche is what costs, daisy chaining the power is usually pretty simple if the deck boxes and near each other. Without the decking, increasing the pipe sizes is easier, regardless of the pump. Slower moving water = less friction loss which begets lower energy costs and also improves safety, especially at the suction outlets. While the returns will be smaller, especially with eyeball return fittings in place, feeding them with bigger pipes is beneficial. A 2" pipe can move twice the water at a given velocity that a 1.5" pipe can. Slower moving water through the pipes is less energy lost due to friction. WRT to whether the Hayward vs Pentair filter is better, I personally feel that the Pentair Tagelus is a better top mounted sand filter. The parts it's made from are stronger. A simple example the is easy to see is the stand pipe takes the filtered water from the bottom of the sand bed to the multiport. The Hayward uses a much thinner plastic pipe that is known to crack, leaking sand back into the pool. The Pentair uses pressure rated Schedule 40 pipe, a MUCH stronger material that doesn't crack. The Pentair Tagelus 100D, equivalent to the S310T 500 lb. filter, has a slightly larger sand bed. Pentair's multiports, in my experience, tend to last longer before needing attention/servicing. I am not a big fan of the Tri-Star series but that's what Hayward uses for their variable speed pumps. IMHO, a 3/4 HP Super Pump will give you the flow you need for filtering and backwashing. A simple Intermatic timer set(one for the pool pump, one for the pool sweep booster) is all the automation you need. The light is easily turned on and off with a switch. Changing to a LED fixture will not light the pool effectively with only one fixture. There just aren't enough lumens. Adding fixtures is a very expensive proposition. If it's what you want and are prepared to pay for it, great, but taking apart a pool to change a wall panel isn't an easy task. If the deck is poured, you'll lose the deck too. The addition of an automation controller and variable speed pump is an expensive eye candy set of additions that for your pool, are unlikely to be a cost effective, problem solving set of additions that would, in the long run, make repairs more likely and more expensive. Yes, the variable speed pump would save you on energy costs, but I don't think to the tune of the additional initial costs. If you decide against changing the plumbing size, you must remember to set the speeds/ flows down so they don't exceed 75 gallons per minute or you will starve the pump of water. This will cause a condition called cavitation where the impeller of the pump is spinning but not moving as much water as it was designed to a given speed, wasting energy and generating vibration at the shaft, increasing wear and tear on the pump's bearing, seals, and motor shaft that will reduce it's life expectancy. It will also run louder. The communications from Brand A's controller is different than the communications link from Brand B's pump. While Pentair offers the Intellicom II to help with Pentair's variable speed pumps, it cost's the non Easy Touch/Intelli-Touch controllers expensive relays and limits you to 4 speeds. It makes more sense to match the controller and pump manufacturers on a new installation. A two speed pump with any of the the major controllers is not a problem. They are all similar in how they control the pump and how the pump's speeds are selected which allows interoperability between the brands. The controller need to be configured with a two speed relay, both physically and in it's programming. Since you don't have a south facing roof, I think solar will be of very limited use and would be an expensive disappointment. A heat pump with a solar cover is likely to be more effective and offers a more economical way to heat your pool over a gas fired heater. If the pool is too hot, there are versions that can cool the pool too. If the pool has a return port installed already for an auto filler to be connected, the Letro will be fine. It's not something you can just add to an already constructed pool without going through a similar set of efforts needed for adding a niche. Better is a subjective term. WRT which salt cell I think is better designed, I prefer the Intellichlor because it's electronics are on the cell, not in with the power supply. This offers two significant advantages. The first is at replacement cell time, you get new electronics. The second is the heat in a power supply cabinet will shorten the life of the control board of the other brands of cells. Pentair also offers a larger available unit that will last longer than the Hayward. If you go with a gas fired heater, it should be a 400K BTU unit. How the gas company feeds their meter is their problem. Heaters, funaces, stoves, etc... require a substantially lower pressure but consistent volume after the meter to function correctly. In order to supply the volume a pool heater needs at the lower gas pressure a residential device needs, the pipe size needs to increase. The added size adds a steadying buffer for the pressure as other gas appliances turn on and off. The heater's regulator is a 3/4" line. The shorter the length of pipe @ 3/4", the better. A 400K BTU heater needs at least a 1.5" supply run before it's reduced to the 3/4" connection. Long feed lines need 2" pipe to the meter but I don't get the impression you will need that. The person you spoke to at the gas company may have misunderstood you needs. I have never heard of a gas company having to run a separate line/meter to a residential home. I'm not saying it isn't possible, only unlikely that the existing line feeding the existing meter couldn't handle the additional load a gas fired heater would generate. That is normally just a change in the meter. Meters serve two purposes, one is to measure how much gas is used and the other is to regulate the pressure to the customer's plumbing. Given the information you have shared, I suspect that my replies will give you plenty to think about and will save you some money. Think about the wants/needs/haves ratios and the constraints I have mentioned. If my understandings are correct, you will find my suggestions reasonable. Best Of Luck; Scott

Did you go with a saltwater pool? Did you seal the travertine? How's it held up? I'm in the DFW area looking to use travertine for my pool deck, but the pool builder says the salt will tear it up. He says sealing it could make it slick and we will have to seal it often.

I have ICF blocks. (Insulated Concrete Forms). Any amount for sale. Shipped to any country worldwide. Size: 50â long (127cm), 10â high (25.5cm) and 6â (15cm) wide (with a nominal concrete core of 4â (10cm) ). It is the exact equivalent of 4 CMUs (concrete masonry unit) in area and only weighs 1.25 pounds. The forms are stacked without mortar and are interlocked like a Lego Set into which reinforced concrete is placed, creating a wall and foundation with a fraction of the labor of conventional CMU. Please email with details of quantity needed. Country to be delivered and target price to: garyjmcneish@gmail.com

thanks for the comments, both! So, indeed orange peel/fisheye. He tried something yesterday, by buffing down and treating it with something. Then reapplied the top coat. It was much better, but the pattern is still there so he's going to have to sand right down. The issue is that the source of the problem cant' be identified. We went over the many different potential causes. He repaired 2 sections of flooring from damage and removal of marble in front of the fireplace, and the effect was present on the new wood as well. So that to me, logically, means it's not parafins, oil or silicone residue in the wood. Also, the orange peel is uniform over the entire 500+sqft of floor. Humidity, temperature, air flow etc are some others... I raised contamination (applicator, batch of finish, residual sawdust etc) but I suppose that I would agree that it would be extremely strange to have the effect cover the entire floor if it was contamination. He's not spraying. It's still possible but... likely its the application, or the product. It happened after the 3rd coat. Other floorers he consulted mentioned a couple of similar cases - after the 3rd coat. He was confident that there was enough time to cure between coats, but I'll insist that we leave larger gaps and wait. So maybe there's something off with the product or the conditions causing the product to behave like after 3 coats have been applied. Potentially. All to say though, he's sanding down and starting anew. We're disappointed of course, it's been stressful because every time we return home it's a mess. It's delayed the reno, and of course the conditions in the house with dust and fumes isn't ideal over such a long time. This seems like one of those things that is never sure as a cause...? Thanks again for your comments!
