When to Drain and Refill a Pool
Draining and refilling a pool should be considered only when water quality cannot be restored with chemicals. Typical reasons include excessive total dissolved solids, high cyanuric acid, or calcium hardness that make balancing water chemistry impractical. Review your water test results and consult a professional before proceeding.

To Drain or Not to Drain?
Describes common reasons for draining a pool, including poor water quality and the need for maintenance or repairs, and advises consulting detailed guides for step‑by‑step instructions.
Reviewed
Merchant termsMerchant location terms apply
Best Time of Year to Drain and Refill
The optimal seasons for draining and refilling are spring and fall, when temperatures are moderate, storm risk is lower, and there is ample time to complete the process before extreme weather. Avoid draining immediately after heavy rainstorms due to elevated groundwater pressure, and avoid doing so before annual water usage calculations are completed, typically in the first quarter of the year.

How to use a In the Swim coupon
- Choose an offer above and read its conditions. Copy the code if one is provided.
- Open In the Swim and add eligible items to your basket.
- For a code offer, look for a promo-code or discount field in the basket or checkout and apply the code. No-code offers may apply automatically; follow the offer instructions.
- Check the discount, delivery cost, and final total before paying.
Why might a In the Swim code not work?
A code can fail because it has expired, has already been used, excludes your items, needs a minimum spend, or is limited to a particular account or country. Check the offer details, remove extra spaces, and confirm whether another promotion is already applied. Try a different offer if the conditions do not match your order.
A past success is a useful signal, not a guarantee for every basket. After trying an offer, share whether it worked to help other In the Swim shoppers.
