⭐ **WATERSTOP for Swimming Pool Construction
Selection Guide + Specifications
(Winwinpool Standard by Pool Size & Concrete Thickness)**
A waterstop is a critical rubber component used to prevent water leakage through concrete joints in swimming pool structuressuch as floor-to-wall joints, cold joints, and expansion joints in deep or commercial pools. Selecting the correct size and specification is essential for achieving long-term waterproofing performance and minimizing the risk of leakage.
Winwinpool waterstops are manufactured according to TIS 11352544 and AASHTO standards, ensuring structural-grade quality. Material properties include:
Hardness: 69 Shore A
Tensile Strength: 24.1 MPa
Elongation: 510%
Water Absorption: 0.9%
⭐ **Waterstop Classification System by Winwinpool

⭐ Professional Tips from Winwinpool Engineers
Match the waterstop width to the concrete thicknessnot the pool size
Use 3-rib models for areas with movement or high pressure
Use Heavy Duty (9.5 mm) for high-risk or multi-pour concrete joints
Use Standard (5 mm) for residential pools and non-movement joints
Always position the waterstop in the center of the concrete joint for full sealing efficiency

A cracked or burst salt chlorinator cell housing is a problem that shocks many pool owners. The chlorinator appears to be running normally, but suddenly you hear a loud “pop,” followed by water leaking from the system. Many people assume the unit is low quality, but in most cases, the real cause is not the machine itself — it is when the salt chlorinator continues operating without actual water flow through the cell.
Even when water is not flowing, salt water may still remain trapped inside the cell housing. If the chlorinator keeps producing chlorine from this trapped water, chlorine quickly turns into chlorine gas. The gas pressure builds up rapidly inside the housing, which can eventually crack or explode the clear plastic outer chamber.
The most common situations include: (1) closing the inlet and outlet valves during pool vacuuming to prevent sediment from entering the cell, then forgetting to reopen them; and (2) running filter backwash in AUTO mode where the pump and chlorinator operate together, but the water flows directly to the waste line instead of passing through the cell. This issue is especially common in models that use electrode-type water sensing, which can be inaccurate when water is trapped but not flowing.
The best solution is choosing a salt chlorinator with a real Flow Switch, such as the Laswim SR Series. A Flow Switch instantly stops operation when there is no real water flow, significantly reducing the risk of cracking, leakage, and costly repairs while extending the equipment lifespan.
The New Year holiday is a time when many families travel to other provinces or overseas, leaving their homes unoccupied for several days. For homeowners with swimming pools, this often leads to concerns that the water may turn green, develop unpleasant odors, or require costly cleaning and water replacement upon return.
In reality, closing a swimming pool for 7–10 days is not difficult if the correct water care principles are applied. The key is proper water preparation before leaving, using the right chemicals to work in place of daily maintenance. This approach helps control algae growth, bacteria, and the accumulation of dirt during periods when the pool is not in use.
This one-time, 10-day pool care method is designed for residential pools and can be applied to both homes without automatic control systems and those equipped with Smart Home or Smart App monitoring. It allows pool owners to reduce system operation while still maintaining stable water quality throughout the holiday period.
When chemicals are selected correctly and adjusted according to pool size, homeowners can return from their trip to find clear, clean water. With minimal effort—such as vacuuming settled debris—the pool is ready for immediate use, eliminating the need for draining or refilling and ensuring a stress-free return home.
Chlorine 90% is an essential primary sanitizer for every swimming pool, regardless of whether it uses a salt system, mineral system, ionizer, ozone, UV, or other health-oriented treatment systems. These systems function as secondary sanitizers and cannot kill bacteria as rapidly as chlorine. If the water becomes cloudy, develops an odor, or experiences heavy usage, chlorine should be added immediately to restore water quality. Maintain a minimum chlorine level of 0.5 ppm to protect swimmers from newly introduced contaminants. Keeping chlorine in stock ensures your pool remains safe at all times. Store chlorine in a dry area, tightly sealed, and away from moisture. If you need guidance on dosage or product selection, feel free to ask anytime.
