How Long Can a Pool Be Empty? Safe Duration & Risks

Replaced my old above-ground pool with this inground concrete setup that needs major repairs, but I've never dealt with draining one before and I'm worried about structural damage. The pool will be without water for potentially several weeks while contractors complete the work.

What are the specific time limits before hydrostatic pressure becomes a concern? Are there differences in safe empty duration between inground concrete pools versus above ground pools with vinyl liners? I want to avoid any structural damage or liner issues during this extended maintenance period.…more

Can Fiberglass Pools Leak? Yes - Here's How to Fix It

Looked like just a minor water drop in my fiberglass pool last month but now it's become a massive leak draining faster than any evaporation. I've heard people say fiberglass pools don't leak like other types, but that can't be true, right?

I'm wondering if there are common spots where fiberglass pools develop leaks? I'm hoping this is something that can actually be fixed without having to tear the whole thing apart. Has anyone dealt with this before and found a solution that actually works?…more

Can Pool Leak Through Hydrostatic Valve? Detection & Repair

According to my pool's behavior, the water level started dropping steadily yesterday even though nobody's been swimming, and now I'm wondering if the hydrostatic valve is leaking. The water level drops consistently even when the pool isn't in use, and I've already ruled out obvious surface leaks around the skimmers, returns, and visible plumbing.

From my understanding, hydrostatic valves are designed to prevent the pool shell from floating during high groundwater conditions, but I'm wondering if they can work in reverse - allowing pool water to escape when groundwater levels are low or if the valve mechanism fails. The water loss seems to correlate with our recent dry spell, which has me questioning whether the valve could be stuck open or damaged.

Is it technically feasible for a hydrostatic valve to cause pool water leakage, and if so, what specific failure modes should I be looking for during inspection?…more

How to Drain Above Ground Pool - Complete Safety Guide

Three different sources are telling me wildly different drain times for my above ground pool — my contractor says 6-8 hours but the pump manual clearly states 2-3 hours maximum. Now they want to charge me $300 just to drain my above ground pool for the winter! That's ridiculous.

I know I can do this myself but I want to make sure I don't mess up my liner or damage anything. What's the safest DIY method to drain it? I've heard about using pumps or some kind of siphon thing, but I don't want to risk doing it wrong and having to buy a whole new pool setup.…more

How Long Can You Keep a Pool Closed? Complete Guide

During winter I'm trying to decide between keeping my pool closed all season to save on chemicals versus opening it and dealing with the constant money drain from maintenance. Every time I go to the pool store they're trying to upsell me on some expensive treatment or service. I'm thinking about just closing my pool for an extended period to avoid all these costs.

Can I keep it closed for longer than just the winter months? What's the maximum time I can leave it shut down without causing permanent damage? I'd rather do the work myself when I reopen it than keep throwing money at these overpriced pool companies all season long.…more

How Long Do Pool Liners Last? Above Ground Pool Lifespan

Do Fiberglass Pools Need Liners? Complete Guide

Called three different pool companies this year about whether my fiberglass pool needs a liner and got three different answers—I'm done with the confusion. With vinyl pools, I understand you need a liner that eventually needs replacement every 8-10 years. But what about fiberglass pools - do they also require some type of liner system to hold the water?

I'm specifically looking at installing a 16x32 fiberglass pool (approximately 24,000 gallons) and want to understand all the long-term maintenance requirements. The sales rep mentioned something about a gelcoat surface, but I want to make sure I'm not missing any liner costs in my budget planning. Do fiberglass pools need liners installed, or is the structure itself sufficient to contain the water without additional waterproofing materials?…more

Can I Leave My Above Ground Pool Empty? Winter Storage Guide

The brutal freeze last winter that cracked my neighbor's liner has me questioning whether I should abandon my usual partial drain approach and go completely empty this year.

My pool has been up for three seasons now, and I've always done partial draining and winterization with chemicals, but this year I'm wondering if it would be easier to just empty it entirely.

I'm concerned about potential damage to the pool structure if I leave it empty for several months. The pool sits on leveled ground with a sand base, and we get pretty harsh winters here with freezing temperatures. I've heard conflicting advice - some people say it's fine to empty it completely, while others warn about structural issues. What are the real risks of leaving an above ground pool empty for an extended period, and would I be better off sticking with my usual winterization routine?…more

How to Know If Your Pool Has a Leak - Detection Signs & Tests

Pulled back my pool cover this morning to find the water level dropped three inches overnight, and now I'm panicking about whether it's evaporation or a real leak. The water level seems to be dropping faster than usual, especially after I top it off.

What should I be looking for to confirm whether it's really leaking? Are there specific tests I can do myself, or obvious signs around the pool area that would give it away? I'd rather catch this early before it becomes a bigger problem!…more

How to Winterize Your Inground Pool: Complete Step Guide

Planning to winterize my new inground pool using the same routine that worked perfectly on my old above-ground, but worried the chemical and equipment needs are completely different.

What are the specific steps I should follow for proper winterization? I'm particularly concerned about getting the water chemistry balanced correctly and protecting my filtration system and plumbing from freeze damage. Should I be targeting specific chemical levels, and what's the proper sequence for draining, cleaning, and applying winterizing treatments?…more
