drain, fill, soak how fast can you?

[mader]

Just a fun post.  I just refilled by tub for the second time, and I got to thinking, how fast can one drain the tub, fill it, and get it up to 100/104 degrees and have balanced chemistry.

I did it today in 11 hrs with a 375g tub.  Anybody?

I think the last time I drained/ refilled, it was about 8 hrs for me. I am not including perfect water balance......just drain/clean+rinse/refill/add stuff.... and soak! I was amazed that it was such a short time but it was in SEPT in CA. I could be off by a bit one way or 'tother but I remember that I didn't think I'd get a soak that night since it was well into the afternoon that I finished the fill, and yet I was in the tub before bed!

Takes my spa about 45 minutes to drain, 45 more to refill, then heats water at 5-6 degree per hour.  I've never actually timed it anything, I usually do the drain and fill in the morning, and let it heat during the day, and it's ready to use sometime in the  evening.  I'll be doing this as soon as in March as the weather allows, and the tap water will be very cold, probably less than 60 degrees to the water heating alone will take a good 10 hours.

Really 10 minutes, (32 gallons a minute) or is that just a "figure of speech?"

I have a submersable pump from Homodepot, and I paid about  that price, but it takes me more like 40 minutes to drain my 320 gallon tub.    I have it connected to a very long ( 100' ") garden hose. Perhaps this is limiting my time?  I don't need to run a 100 feet of hose,  it's just what I had hanging around. Is such a long hose significanlty effecting my drain time?

The heat back up part is a big variable for me.  My water out of the tap this time of year is close to 40F.    In July it can be 75-82.   At 5 degrees an hour, that is a difference of 6 hours right there.

You wish!  

[drewstar]

ouch.  

Pehaps I need a wider hose? Is it more a function of girth than leangth?

I have a small sump pump ($85 or so from the depot) for mine as well. I connected about 15 ft of 3/4" garden hose and it took about 10-15 min to drain my 300 gallon tub. I've seen folks use a 2" vinyl backwash hose when draining swimming pools. They are cheap and fold flat when not in use.

I drain the old fashion way with the help of an extra hose.  Usually take about 1.5 - 2 hrs to drain, 1/2 hr to clean, maybe an hour or so to refill, and forever to heat.  If I start around 8am, I should be able to soak around 10 pm.

45 minutes to drain using pump and 100' hose
30 minutes to fill
5-6 degress/hr to heat

Did mine Sunday.

blue flat pool draining hose works the best.  using a garden hose slows things way down.  420 gals in ten minutes, 15 may be.....

I guess I paid more than $85.

Here it is....check it out

if one has a submersible with a 1 1/2 outlet, one should use 1 1/2" hose... anything less will prolong the outcome...

I haven't done it yet but I know my first heat up took about 30 hours on 110...so I don't think I will be setting any records in this thread!
