Thanks for the replies. I usually err on the side of caution, so I will probably end up doing the sand over caulk. I will probably experiment on the deep end with a couple different methods and products. I get that caulk is designed to flex with any expansion/contraction and provide a...

I am nearing completion of a pool remodel and trying to decide whether to use a semi-self-leveling caulk to fill the expansion joint between the coping and pool deck or to just grout it. As background, my coping is 12" by 24" bluestone and my pool deck is irregular shaped marble wet-laid on a...

There should be an expansion joint between the coping and deck so movement in one does not affect the other. That joint should be filled with a product that allows expansion/contraction. Polymeric joint sand may allow for this movement, but I think it would be best to use a caulk-like joint...

Thanks! My main drain line is approximately 45' and my skimmer is approximately 30', so I averaged the two.

I cannot find a model number on the pump itself anywhere. The pump is quite old so I wanted to go ahead and replace the entire unit.

Sorry I did not see this sooner. I had a friend that had a similar thing happen to him. He was running his pump through the main drain only and leaves clogged up the main drain creating a vacuum effect that raised the hydrostatic valve. The springs in the valve were either compromised by this...

I am looking for help in choosing a replacement pump. My old pump is a Hayward 1HP pump (single speed). It has an AO Smith motor Model C48L2N134D2, Serial Number 30508FM, RMP 3450, Amp 18 6/9.3. My pool is 45,000 gallons with an average of 37 1/2 feet of head. My filter is a Hayward 300...

As an update, the particles continued to settle to the bottom. After vacuuming to waste followed by vacuuming through the filter a couple of times over the weekend, the water has cleared up tremendously. Still a very slight greenish hue this morning, but it appears I have the iron (if that is in...

I have not added the cyanuric acid yet. Doing that tonight. CYA of 40 and target FC of 5 ppm has seemed to be a good balance in the past, but that may change since my pool is (hopefully) no longer leaking now.

My pool is in the shade in the morning until about 11:00. I usually average about a 96 oz jug of 6% a day. Which takes my pool up about 1 ppm (makes the math easy!). I wonder if the deeper water helps with the consumption. Thanks again for your help. I will vacuum to waste tonight. And...

Thanks again for your help with this. I usually keep the pool on the higher side of the recommended range for TA (70 to 90+). So I did intend to increase the TA that much. In hindsight, I probably should have stepped it up incrementally. So should I quit adding bleach? Is it better to...

Still no luck getting anybody to answer the phone at the water treatment plant. Just read the article "Metals in the Water and Metal Stains" on TFP. The below statements in that article have me questioning whether it is iron: "Iron is fairly common in well water but rare in municipal water."...

The lady at the water department looked up my account and said that our supply was not from a well. She did not know any further details of the water makeup though and gave me the number to the water treatment plant. I have called, but have not gotten in touch with them yet. I read...

I just finished remodeling my pool, which required draining. I was very nervous about it floating when draining or during renovations. As the water went down, I drilled two 1/2" holes in shallow end, two on the top of the slope, two toward the bottom of the slope, and three in the deep end...

Thanks, chem geek! Jackson, MS 39216

I just finished remodeling my pool and refilling it. The refill process took three days. As expected, the water turned green since I was unable to run the filter until the water level got over the return jets. Last night I was impatient and decided I would go ahead and get chlorine started...

I wouldn't accept the electrical either. Simply meeting code is not the standard. Putting it in front of your plumbing not only looks bad, but blocks access. Why didn't they just put it on the wall a little further away from the fence closer to the equipment pad. Or if there was not enough room...

Thanks everybody. I didn't think it would pose a problem, but wanted to check. I am not really looking to improve performance, although that would be nice. I already have the deck torn up, so I was going to dig down in the yard to minimize the fittings I put under the deck. Since the equipment...

I am in the process of renovating my pool and replacing my skimmer. All the lines are 1 1/2", but rather than transition from the 2" skimmer to the old 1 1/2" pipe, I was thinking about just running new 2" all the way to the equipment pad. Will the 2" skimmer line cause any problems when the...

Thanks for posting. It is looking great! I am about to start a similar project. Did the pool contractor mention why he installed the tile before the coping? From what I have read, it seems like the coping is usually installed first. I will be matching an existing deck height like you, so...

Thanks, Chris. I had not heard about that forum. At first glance, it looks very helpful.

Thanks for the reply. I am in Jackson, MS, so freezes aren't too bad. I leave pool running year round. We are looking at two different tiles - both glass mosaics that specifically say they are fine for pool use. One is manufactured by Sonoma Tilemakers. I can't remember the other...

The current coping is the old 12" by 24" pre-cast concrete bullnose pieces. Replacing it with bluestone which is same dimensions and almost the exact thickness.

I am planning to replace my coping and water tile in the near future. I have read much on this site and the internet in general. It seems there are differing opinions about the need to water proof behind the water tile with a product such as Laticrete Hydro Ban. Are there certain situations...

I do believe that is what happened to me too. Thanks for the confirmation. Maybe others can avoid a similar mistake.

Mark, thanks again for your willingness to help and for sharing your knowledge. I took a screwdriver and could tilt/rock the switch back and forth. I can spin the shaft with my finger, about a half turn at a time. It has some resistance and if I put my ear to the outside of the motor I can hear...

Thanks for the reply. I am not exactly sure how to tell if it has a centrifugal switch, but from your description (a switch that should disengage the capacitor once motor starts), I believe it does. It has a device near the capacitor with two springs. Looks like they would rock or tilt a...

I just replaced the start capacitor on my pump motor (AO Smith C48L2N134O2). The motor was humming, but not starting. The capacitor tested bad. New capacitor started it up with no delay. The motor ran for a couple of hours and turned itself off - it is thermally protected. When I realized it, I...

OK. Here's the additional info. The pump is a Hayward 1 HP. The filter is a Hayward Pro Series Sand Filter 300# Any advice on whether these are sufficient for 45,000 gallons is appreciated. We bought the house/pool last year and I remember it being a struggle to get the water clear then...

Last time I checked the CH (about 2 weeks ago) it was 220. 45,000 gallons. Plaster. Not sure of filter size, but will check tonight and post. It was keeping up last year when I had the water crystal clear, but I do remember having trouble getting it clear. Also, the pressure typically runs...
