They screw into the bottom or front of the pump basket housing and their only job is to let water completely drain out when you need it to.<\/p>\n<p class=\"p1\">Leave them in (or lose them and never put them back) before a hard freeze, and trapped water turns to ice, expands, and splits your pump housing wide open.<\/p>\n<p class=\"p1\">We\u2019ve been fixing pools here since May 2018, and every February the most common freeze-damage call we get is a cracked pump \u2014 almost always because those two little plugs were either forgotten or missing.<\/p>\n<p class=\"p1\">Here\u2019s everything you need to know so your pump survives another Texas winter.<\/p>\n<p class=\"p3\"><b>What Pump Drain Plugs Actually Do<\/b><\/p>\n<p class=\"p1\">Your circulation pump is basically a big plastic bowl full of water. When the pump is off, gravity keeps that bowl filled right up to the pool water level.<\/p>\n<p class=\"p1\">When temperatures drop below freezing and the water sits still, it expands about 9 % as it freezes. That expansion has nowhere to go except to crack the pump housing, blow the lid O-ring, or split the volute (the front half of the pump).<\/p>\n<p class=\"p5\">The drain plugs are the emergency escape hatch. Unscrew them \u2192 water drains completely out of the pump basket \u2192 nothing left to freeze \u2192 pump stays safe even at 15 \u00b0F.<\/p>\n<p class=\"p1\">Every major brand has them in roughly the same spot:<\/p>\n<ul class=\"ul1\">\n<li class=\"li5\">Pentair (IntelliFlo, WhisperFlo, SuperFlo, etc.) \u2192 two clear\/white plugs on the lower front of the basket<\/li>\n<li class=\"li5\">Hayward (TriStar, Super Pump, MaxFlo) \u2192 two plugs on the bottom or lower side<\/li>\n<li class=\"li5\">Jandy (Stealth, PlusHP, FloPro) \u2192 usually two on the front face or bottom<\/li>\n<\/ul>\n<p class=\"p1\">Not sure where yours are? Snap a quick photo of your pump and text it to us \u2014 we\u2019ll circle them for you in two minutes.<\/p>\n<p class=\"p3\"><b>Why These Plugs Disappear More Often Than Socks in the Dryer<\/b><\/p>\n<p class=\"p1\">They\u2019re small, slippery when wet, and usually clear or white \u2014 the trifecta of \u201cgone forever.\u201d<\/p>\n<p class=\"p1\">The most common ways they vanish:<\/p>\n<ul class=\"ul1\">\n<li class=\"li1\">Taken out to drain the pump and set down \u201csomewhere safe\u201d (i.e., the grass)<\/li>\n<li class=\"li1\">Fall into the pump basket and get tossed with the leaves<\/li>\n<li class=\"li1\">Kids think they\u2019re toys<\/li>\n<li class=\"li1\">Go through the washing machine in a pocket<\/li>\n<li class=\"li1\">The dog carries them off<\/li>\n<\/ul>\n<p class=\"p1\">We keep a coffee can full of spares on every truck because we hand them out constantly in fall and spring.<\/p>\n<p class=\"p1\">Pro move: The instant you remove them, drop them straight into the pump basket or skimmer basket. That way they\u2019re impossible to lose and are right there waiting when you reassemble in March.<\/p>\n<p class=\"p3\"><b>What Actually Happens When Water Gets Trapped<\/b><\/p>\n<p class=\"p5\">Water stays in the pump basket \u2192 turns to ice \u2192 expands \u2192 plastic has to give somewhere.<\/p>\n<p class=\"p1\">The result is almost always a cracked pump housing or volute. That\u2019s not a $200 fix \u2014 it\u2019s a new pump (or at minimum a new wet end) plus labor. Even on older single-speed pumps that\u2019s $800\u2013$1,200. On today\u2019s variable-speed pumps it\u2019s $1,800\u2013$2,800 easy.<\/p>\n<p class=\"p1\">We see it every single year, and it\u2019s 100 % preventable.<\/p>\n<p class=\"p3\"><b>How to Check and Use Your Drain Plugs Right Now<\/b><\/p>\n<p class=\"p1\">Takes 30 seconds:<\/p>\n<ol class=\"ol1\">\n<li class=\"li1\">Walk to your pump (the big thing with the clear lid on top).<\/li>\n<li class=\"li1\">Look at the very bottom or lower front \u2014 you should see two small knurled knobs or slotted plugs.<\/li>\n<li class=\"li1\">They should be finger-tight and have intact O-rings.<\/li>\n<li class=\"li1\">If either is missing, cracked, or the O-ring is shredded, replace it now while the weather is nice.<\/li>\n<\/ol>\n<p class=\"p1\">When a hard freeze is forecast:<\/p>\n<ul class=\"ul1\">\n<li class=\"li1\">Flip the breaker off<\/li>\n<li class=\"li1\">Unscrew both plugs (drop them in the basket!)<\/li>\n<li class=\"li1\">Let the water drain completely onto the pad<\/li>\n<li class=\"li1\">Leave them out until the cold snap passes<\/li>\n<li class=\"li1\">Screw them back in before turning the pump on again<\/li>\n<\/ul>\n<p class=\"p1\">If we handle your professional winterization, we do this (and every other drain point) automatically.<\/p>\n<p class=\"p3\"><b>The \u201cI Have No Idea Where Mine Went\u201d Fix<\/b><\/p>\n<p class=\"p1\">Replacements are cheap, universal, and easy.<\/p>\n<p class=\"p1\">We stock every common size on the trucks and are happy to drop off a pair (or four) next time we\u2019re in your neighborhood.<\/p>\n<p class=\"p1\">DIY Assist members \u2014 we check all drain plugs (pump, filter, heater, everything) and replace missing or damaged ones at no extra charge during your visits.<\/p>\n<p class=\"p3\"><b>Bonus Tips to Never Lose Them Again<\/b><\/p>\n<ul class=\"ul1\">\n<li class=\"li1\">Buy four spares today and keep them in a labeled Ziploc taped inside your equipment area<\/li>\n<li class=\"li1\">Wrap bright tape or a neon zip-tie \u201cflag\u201d around them<\/li>\n<li class=\"li5\">Sharpie \u201cDRAIN PLUGS GO HERE \u2192\u201d with an arrow on the inside of your pump lid<\/li>\n<li class=\"li1\">Take a phone photo the day you remove them so you remember exactly where they live<\/li>\n<li class=\"li1\">Ask us to sticker the spots when we\u2019re out \u2014 we do it standard for every DIY Assist customer<\/li>\n<\/ul>\n<p class=\"p3\"><b>What Now?<\/b><\/p>\n<p class=\"p1\">Your pump drain plugs are two of the smallest and cheapest parts on your pool\u2026 and forgetting about them is one of the most expensive mistakes you can make in winter.<\/p>\n<p class=\"p1\">Go find them today.
