Question about Pool & Spa

1 Answer

I have an older inground pool that has a steel liner (from what I am told, this is the old type). I am now noticing rust on the liner, in different places all over it. My ph level is fine, my chlorine level has been a challenge but we try to keep it in range, and the alkalinity is high. Any idea what's wrong - the alkalinity maybe? Any way to get rid of it?

////////////Detecting The Hole In A Leaking Pool Liner////////////

Pool liner has a hole in keep adding water far too many times a week running up your water bills far to call a pool guy and he recommends a "Diver" to call, when you call the diver you fall through the floor when he tells you the initial cost no matter whether he finds the leak or not.
This is what i have learned from the experts....had a pool diver come over and all he did was 'Nothing"...he charged me $400.00 took out and resealed my lights...broke my brick stones around the pool in various places due to his removal of the air tanks, talked a good line of balogna, took my check and left....left me $400.00 lighter in my wallet and no better off then I was before concerning my pool liner leak, he even told me after he came back to find it three times again that the leak was all in my mind and that the dropping of the water level was due to evaporation... this is all good fior someone who is new to a pool...but I have had this inground pool for 10 years prior to him telling me he usually always finds the leaks....he did not and tried to cover his inadequecies with a ration of bull stories...I was adding at least 2-3 hundred gallons of water everyday whether it was hot out or cold out, and this only started happening after about 10 years of owning the pool, in this case it didnot pay to have someone dive the pool because when you can see a real strong discoloration in your liner and the water level starts to drop all of a sudden every other day to at least 1/2-1.0 inches it is time to replace the liner.
If you have a newer then 8-10 year old liner by all means have it tested before you replace it, a cheap and inexpensive way to do this is to start at some point... I would first buy a $4.00 rubber plug to plug up the bottom drain....see if the water level drops...if it does problem is someplace else if it stops dropping the prblem is in the drain lines and that can be an expensive fix for an inground pool short of just leaving it plugged and never using the bottom drain feature again.
If the drain plugging doesn't fix the problem try blocking off the lines with plugs one at a time until you find the level stops dropping indicating which line is culprit, including the skimmers and please be sure you leave the filter off while doing these tests.
If none of the above finds the leaks get in the pool and being very still discharge a small puff of red food coloring under water around the light lense frames...trying to see if it gets sucked into a leaking area, also around the stair case if so equipped doing the same thing with the dye around the seams etc.
You may even find the filter is leaking at a joint causing the leak, or like i once found.... little under ground critters ate my skimmer lines... they punched pin holes into the rubber buried lines with there teeth...they were small moles, nocturnal like rodents that burrow under ground causing havoc on anything that is buried beneath the surface....I found this problem easily...the ground all of a sudden became wet and damp and eventually started to pool up with water for no apparnt reason...when I dug into the water pool I found a little gusher of water coming from the lines, these critters ate into the lines...had to cut them and couple them with a sleeve for the fix.

How to Last Minute Rush an Inground Pool Vaumning

Did you ever want to just get the pool vac'd., without getting out the robot if you even have one, or pulling out the vacumn and hooking up the hoses, having to purge all the air out of the system just to get it know the drill....and to make matters worse its real hot out!!
her's what i have found in my years of pool cleanup blunders, Put the pool selector valve to pool drain, get a long adjustable handled pole with a leaf type pool brush attachment, very slowly push the grit on the liner towrds the pool drain, do it gently and stop, wait until the smokey looking water clears(this means it went into the drain port and is being filtered out in the cannister).
Do this to the entire pool but dont rush it, after you are done check the PH and Chlorine etc. adjust, backwash the filter if your filter has a backwash system, and off you go onto another home project, this one just saved you a ton of precious time!!!
If you have the inground pool cartridge filter system you should remove the filter/filters and hose them out twice a year to keep them clear, when they start to look and act dirty and they cant get clean by hose take them to a pool pro and ask him to chemical bath them, thisfilter problem will be noticable when you see the pressure rising too high on your filter tank, it means the filter/filters are getting clooged and need attention.
Happy Homeowning!!

Swimming pool

NOT from Outside.
If Possible empty pool now with a Controlled drain...
Peel back liner and clean area real good. Sand or steel wool to remove rust. Then Paint using one of those "Rubber" based leak sealing paints found in your local DIY warehouse store.
Then place a piece of Thin sheet metal against the wall after paint dried. Replace liner, coping strip, ridgidizing metal bar, and top rail.
or if you're lucky...
Patch the liner. When all is dry, use 3 applications of Epoxy Putty like JB Weld. Place a small covering over the DRY area with the hole. If possible, force some into the hole.
Once dried and cured, place a 2nd patch, slightly larger over it, and then repeating a 3rd time, again slightly larger.
Not as good as First method, but may still work?
If left unattended...
The water pressure in the pool, will push the liner right thru that hole - like a hernia, and will burst thru releasing all your water and possibly collapsing the pool? This will be an "Uncontrolled" drain vs. the controlled drain above.
I guess you can choose which way you want to drain your pool?

Will it hurt to put sand under my 16ft. By 42in. Summer escapes metal siding pool

no --it will be most beneficial
the sad will act a soft base and will protect the liner from sharp rocks etc and will prevent punctures to the pool liner
to prolong the life of the steel sidings paint the inside up to around 6 inches with a bitumastic ( ormonoid or tar ) paint as this paint will prevent rust at the bottom of the sidings from the steel and moist sand
the secret is to ensure that the pool is perfectly level all round and to keep the pool full at all times as the chlorine on the plastic liner will deteriorate the plastic and create pin hole leaks where exposed

Why does pool pump have way more suction than it used to have after 40 yrs?

you can put a ball valve on it and open only 3/4 way or if you have an inground open the main drain and the other skimmer did you upgrade your pump?

We have a Reliance 501 (40 gallon) natural gas water heater Model 5 40 NORT0 Serial F94799798. Does it have a glass liner?

Your Reliance serial number shows your water heater was made in July 1994.

Except for the Marathon water heaters, and copper-tank water heaters, all tank-type water heaters are made of steel. That steel has an enamel coating which people call a glass liner.

So in that sense, there is a glass liner.
See a photo of the liner:

Also inside the tank is an anode rode.
The anode is made to protect the steel tank.
Anode is made from lower noble metal than steel, so water reacts with the lower noble metal first.
The water eats away the anode rod instead of rusting the tank.
Once the anode rod is gone, the water begins rusting the tank.
The enamel coating does not protect the steel from rusting.
The tank rusts away and begins to leak.,,20047047,00.html

We found out tpday that we have 19 leaks in our inground pool liner which is not quite 2 years old!! The only thing we've changes this year is we purchased a Barracuda Robotic pool cleaner. Have you ever...

It will have a strong suction to the pool floor and could grind bits of sand into the liner. You might want to try a Arneson Pool Vac.
Be sure they put cork feet on it though so it goes easy on the liner.
If and when you replace the liner be sure to put an under-liner down first. This will help with problems that run along these lines.

Inground pool liner

need to drain the pool pull up the trim see if you can stretch the liner back into position (works best on hot sunny day doesnt work at all in cold weather). Alot of pools have a u shaped groove the liner goes into then plastic tubing is hammered into the groove (a similar application is screens for windows and the spline that holds the screen in place). I also use a shopvac to "pull a vacuum" on the liner to help pull into sides of pool before filling. If your liner is more than a few years old or was trimmed too short you are probably out of luck
