Winter-water change
« on: September 20, 2004, 08:59:21 am »
Seems to me a everyone agrees on this board that
a spa newbie will screw up his water.  Most also agree
that the best time to buy a hottub is in preparation for
the colder weather.

This puts me in a situation that others must have been
in before, if I install my tub at the mid-end of Oct, my
first water change will be in the famous Canadian winter.

Is this a problem?
It can't be fun?
Thoughts?

well if you do like i did.  you will screw up your water the first time.  so you will probably have to change it much sooner.so if you buy in oct. figure on your first change around dec.  then maybe you will be good till almost march before you need to again. :o

Good Question..!

Does anyone here have any tips for winter water changes (ie very cold Canadian temperatures)...?

Although our water is good for now, the change-over would likely occur in Nov or Dec.

I live in Minneapolis, so we've got this issue to deal with as well.  What I did last year, which was the first winter we had our spa, was to wait until very late October or early November to change the water.
Then we just rode it out till early March, when things warmed up enough to change again without the threat of freezing.  It worked, we went just over 4 months on that water.  Longer than I'd prefer, but I can't see changing the water in 20 degree or lower temps.  
The water was fine, btw.  
One thing I did consider but didn't do is a partial water change, remove maybe 1/3 or so, and refill.  
I shut off the water to the outside spigots in the fall, and you probably do likewise.  We could put a hose on the sink in the basement, and run water to the spa if we had to.

I change my water in early December and it lasts until early April.  So far I have been able to avoid any winter water changes, though I usually need to add about five gallons per week due to increased evaporation.

I was going to replay but Brewman covered it. In soutnern Ontario I see most of my customers draining in mid-end of November and riding it out till Spring.

Happy Tubbing!

Maybe this will make  you feel a little better too...  A service tech of ours came in to pick up some paper work the other day and told us about his last appointment.  He said the lady has owned her spa for a little over two years and was not aware that you are supposed to change the water.  2 year old water!  Grooss (I said) and the tech said "Actually, her water was crystal clear".

A side note:  Warm water in a pipe will freeze faster than cold water.

AHH HAAA!!!

I quote:

"He said the lady has owned her spa for a little over two years and was not aware that you are supposed to change the water.  2 year old water!  Gross (I said) and the tech said "Actually, her water was crystal clear".

I did a post on not changing water a few weeks back and most people thought I was CRAZY.

Why change water if the chemistry is good and the water is clear?

How often do large pools and water parks change THEIR water?  I bet these places get a LOT more worse stuff in them then hot tubs.

I usually don't change the water in my tub.  I only add water or remove water (displacement for more than 4 people).

Why waste water when you don't need to?

It's a HOT tub... anything else is just a POOL!

Comfort Factor.  If you are comfortable sitting in the same water for 2 years...by all means do it.  It's your tub/water/filth.  Keep in mind that you do perspire in the tub (amongst other things)  and 2 years of perspiration can amount to quite a bit.  If you don't mind soaking in it, it doesn't matter.    

Of course you also have to take into consideration that the water will need more adjustments over time (ie. spend more on chemical balancing) and there is of course that whole TDS thing.

Keep in mind; we don't make money on your water bill.  If you fill every 5th day, we don't see any benefit.

This worked great for me last winter, and I will use that technique to carry my current water till early Nov.  I'm fortunate, I don't have to turn my outside spickets off and I have two within easy reach of the tub. I keep both hoses in the basement in the laundry room.  Only once in 20 years of living here have we gone more than 30 days without it going above freezing. But even below freezing, I can refill my tub in 30 minutes with both hoses.  Of course in Jan, the water out of the spicket is around 45 degrees and that takes a long time to get back to 102.

Sometime last January, in the middle of a really cold snap, temperatures near zero, I discovered that "someone" left the cover unlocked, and "somehow" it got flipped open.  I have no idea how long it was like this, but I lost about 60 or so gallons of water to evaporation.  I eneded up toting out refill water in 5 gallon pails.  Yech.  I was too lazy to go get the hose out of the garage and pipe it out of the laundry tub, but not too lazy to lug over a dozen heavy buckets of water the 25' from the laundry tub to the spa.

Ummmmmmm who told you this? Warm water takes longer to cool to freezing than cold water but the difference will be minumal at best. Not a noticable consideration. Now if you throw warm water in the air and it is 20 below it will crystalize where cold water won't but that has to do with molecules bouncing off one another. Warm water is however used in commercial ice machines, but not because it freezes faster but because it makes clearer ice, again molecules and less oxygen in the water.

Huh? is absolutely correct  ("warm water in a pipe will freeze faster...")  And the reason is exactly as stated by Tman ("less oxygen in the water.")

Common knowlege to plumbers who fix frozen pipes in winter:  The hot water heater in your basement drives the oxygen out of the water.  Hot & cold line both running along a cold foundation wall = ice forms in the hot line first (remember, overnight the water standing in the pipes does not stay hot, they both cool to the same temp, one side has reduced oxygen.)  The cold line may be the one to burst but only due to a weak spot in the pipe wall.  Ice crystals will form first in the reduced oxygen (hot water line) side. ;)
