cravnravn Posted January 11, 2014 Share Posted January 11, 2014 I have a 2 1/2 inch drain pipe and 9600 gallons of water, how long will it take to drain? Don't know if it matters but the pool is 16 x 20 and the depth is from 2 ft to 5 1/2 foot Quote Link to comment Share on other sites More sharing options...

dc. Posted January 13, 2014 Share Posted January 13, 2014 Is this above ground? Either, do you have a flow meter? That's what I'm looking for... Your pump creates certain flow, just divide total gallonage of pool by flow in gallon/min. Quote Link to comment Share on other sites More sharing options...
cravnravn Posted January 13, 2014 Author Share Posted January 13, 2014 It's an in ground pool, I'm hoping all I have to do is release the backwash valve, I have a 50 ft hose and I'm aiming it towards the lake, Quote Link to comment Share on other sites More sharing options...

cravnravn Posted January 13, 2014 Author Share Posted January 13, 2014 Come on now do you really think I would dump chlorinated water into the lake? I haven't added chlorine since thanksgiving weekend, this is my Feb project, to repaint the pool. There is no chlorine in the water at all, besides I fish that lake I wouldn't harm it Quote Link to comment Share on other sites More sharing options...
cravnravn Posted January 13, 2014 Author Share Posted January 13, 2014 f50' of garden hose?No, I have 25 feet of vacuum hose and I'm buying 25 ft that will connect to it, that'll get me to the drain to the lake Quote Link to comment Share on other sites More sharing options...
oldcrow Posted January 14, 2014 Share Posted January 14, 2014 okay good deal all I can think of now is when you have it emptyyou're gonna breakout the skateboard cut off blue jean shortshang ten tank topchuck taylors with purple tube socks pulled up to your knee capand a ravens headband Quote Link to comment Share on other sites More sharing options...

dc. Posted January 14, 2014 Share Posted January 14, 2014 Ultimately, short answer isn't it won't take long as you probably get 100+GPM easily... And so long as its legal and the water is clean, you can run a backwash or a flush (flush/rinse) is better if your pump/valves have the option. At 100GPM, it would take 90min to empty... No?

cravnravn Posted January 16, 2014 Author Share Posted January 16, 2014 I'm going to slow the flow down to 15 gallons a minute. That should get me around 6 hrs to drain. Now I'm reading a section in hydrostatic lift, and why Johnny homeowner should not drain his pool, Ok so there's a valve by the drain that I need to open to release water that could be trapped under the pool,if there is water under there and you don't open the valve the pool will float up causing major damage to the concrete patio surrounding the pool as well as ruin the pool shell itself, Bottom line is cost a pool contractor wants 2800 to resurface my pool, when I can get all the supplies I need for under 400.

oldcrow Posted January 16, 2014 Share Posted January 16, 2014 especially the floorit'll buckle with uplift of the ground watercracking the floor creating washout of your subgradethen you're in a world of doodooespecially with any freeze thawwhich is low possibility but always a concern the way some people build poolsthey leave out reinforcing steel and mesh which will weaken the strength of your concrete I guessing it is guniteand probably low quality on top of thatthey are not required to have certifications of proper application EVERYONE IN THE POOL!!!!

dc. Posted January 18, 2014 Share Posted January 18, 2014 Lots of reasons to not empty your pool - but most of those are about long-term emptying. If you can get the job done in a week or so, you should be ok. But inground pools are meant to have water in them; it's not just nearby water that can cause issues - its also just the pressure of the ground nearby, etc that push on the pool when there is no water there to push back.
