Stripping out liner!!

Recommended Posts

I have to have a new liner fitted and I am taking the old one out. The liner itself is a doddle, but is there any way of removing the felt under it? It's coming off, but is leaving like hairs of it behind and I haven't got to the WET bits yet!!

It has to be changed because it's leaking like a sieve and I believe that when anyone was in the pool it was pressing the water from behind it back into the pool and causing the water problems I had been having! Can't be too bad for a liner that is at least 20 years old though?

How 'clean' does the concrete pool 'hole' have to be before the new liner is fitted as well? Any ideas please?

As clean as you can get it but the felt layer should go back in and on the bottom too.  I fold the felt at the top to form a double thickness to fill the small air gap created by the liner lock as it prevents dirt and small gritty bit's from commencing their journey down the side of the liner.

Ta for the quick reply TP. I have found that the felt is on the bottom too, but it's going to be a real cow to remove it. I have been using a garden hoe and if that is the only way it is going to be a long hard job!

The felt that will pull off and leave the hairy stuff behind, I have found that my gas blow lamp gets rid of that, but that's only going to work on the walls. Do you have any other ways to get the felt up from the floor mate [8-)] ?

After I had drained as much water out as I could with the pool pump I got a lot more out using a plastic dust pan and bucket. The liner was floating on a load more that had got under it. I just hope that it doesn't fill too much again if it rains [:-))]

What a star you is TP [B][B] You know more about me than me. I hadn't thought about my Fein?

Fein, I'm goin to live forever! Thinks? I could write a song about that  https://www.youtube.com/watch?v=poNxrtz_p40

I'll have to make sure there ain't any water around for that [:-))]

I wish that it would come out as easily as the liner. I have a lino cutting blade in my knife and it made it so very easy.

I have decided that stripping the felt out is akin to shearing a concrete skinned sheep 9 metres by 4.5 by 1.4 high and by the time I have finished, if I manage to retain the small amount of sanity I have that it won't be a job that I would do for a living [:-))] The Fein works but it's wearing the scraper down at an alarming rate!

After about 4 hours in the pool today I have stripped off about 5 of the 27 meters of wall and doing a rubber, as opposed to a soft, shoe shuffle some of the floor as well [blink][blink] When the bloke comes wot is fitting the liner I am going to ask him how much to remove the rest of the  bleedin felt. Life is too short for that kind of job for me [:'(][:'(]

Such is life or is that say la veeee [8-)]

Well! There was a nice surprise for me when I realised that there isn't much of the floor covered by the felt, so that is almst done now.

The fitting guy has told me that if I can't get all of the felt off by pulling it off then a 'lance du flame' would get the rest off and leave a good surface. So I have spent most of the day in the pool with a good pair of gloves, my 13kg gas bottle and blowlamp and a wire brush. Now I have just one end and one side wall to do with a small bit in the middle where it's still a bit wet.

May well be a rest day tomorrow as rain is forcast?

Then to build a new set of steps and be ready for him to fit the new liner in June [8-|]

All stripped out now. Just a bit of cleaning to do and contact a mate to see if I can borrow his brick glue mixer for the steps.

The GRP steps are up for grabs, but as I can't advertise them on here a PM will give the details..

It was really odd, because the felt came off of the parts that it had been glued to far easier than the parts where it hadn't. It was smoother on the glued bits and the felt was almost ingrained into the bare concrete. So, I finished up pulling the felt off, a very dusty job, then burning off any residue and wire brushing the remainder. It took at least a couple of burns and wire brushing to get some of it off too!

If I ever get the chance to do the same again I will hide!

When the new steps are built in I will pressure wash the whole thing, or should that be hole thing? And it will be ready, I hope for the liner.

Such a shame to loose those wonderfully engineers internal steps you made, I guess that they will be on ebay by and by.

Never mind, I'm sure that you'll make a nicer job of the builtin steps too John.

You know that you'll have to be careful of the details in the liner as your water is so clear that everyone can see the smallest defect.

Of course you know who to thanks for that.

I always make sure that our pool is in peak condition, even when it's going to be emptied [8-|]

I'm not too sure wht would happen now if someone fell in there and the floating safety cover wasn't in place?  [8-)]

The straps aren't long enough to reach the bottom [:-))][:-))]

Edit  :  -  I have to admit Orical, that I had not even thought about advertising them on ebay? I have never bought or sold owt on there.

Well, after a bit of delay due to bone idleness and a couple of weeks in SW Corsica, hell, but someone had to do it? I finally got to doing the steps.

I had thought of hiring a betonier, cement mixer to you and me, but after a look at 'le boncoin' web site I found a second hand jbbie just a few Ks away. So now I am the proud owner of a cament mixer, which I will sell on when I have done with it?[8-|]

A mate came and helped me with the bottom step. He's always good for a laugh and it went well. I carried on with the others. The steps are 30cm tread and 25cm rise. As the blocks are 49 X 19 X 19 it means that there is a 5cm-ish lump of concrete on the top of each layer of blocks, including a skim of morter to give a nice smooth finish.

I rediscovered muscles that I had totally forgotten about, but when I look at the job I have to admit to being quite pleased with the result. I decided to build the whole thing using blocks. I was going to just do the outer 2 lines with blocks and fill the inner bit with rubble, stones and anything that I could egt hold of, but for a few extra €€ it was so much easier the way I have done it.

The 1st step

All it needs now is to get the last bits of that awful felt off the bottom, have the new armoured liner fitted, fill with water and get in theree and enjoy it again [8-|][B]

Ta TP. It was inspected by the guy doing the liner and passed with flying colours [8-|]

Then, I had a look at it last night, after we had some rain, and found our first visitor sat on the second step down looking  very sorry for himself

He could get up and down the steps, but the overhang of the margels was a no no. After a bit of a chase he was in a plastic box and let go away from the pool.

Here part of the liner fitted and as it's an armoured it's made on the spot as it were, just as you said TP

The guy who did the fitting was very carefull and has done a great job. Now the water is going in [:-))]

I 'ope it dun leak [8-)] You can see the blue haze starting to appear and the temp of the water going in will make sure it doesn't take too long to warm up, 24ºC!! I in arf looking forward to getting in there!

You are more than welcome TP. It's looking good now. There is one very small place where the liner has a slight crease, but I will try and 'massage' it out when it's a bit warmer in there. If it doesn't come out then the guy will come back after the season and sort it.. Can't really ask more than that?

The morning after the water went in we had a rain storm early morning and it went a lovely shade of green. I chucked a few ltrs of javel in and now we have the correct colour [B] I was amasing just how quickly it went green! I will let it settle now and see what happens?

Quick update. The water is crystal clear, but the levels aren't right yet

Chlor free      7.26  and doesn't seem in a hurry to drop.

PH                 6.7    and doesn't seem in a hurry to rise.

TA                 93     today, 74 yesterday and 106 the day before [:-))]

Cya acid        25     I have not boosted that at the moment and I hope that it being low will help the clor free to drop. Also, I don't want to knock      the PH down any further by adding more acid.

How, now, do I get the PH up and the chlor down??? And any ideas why the TA changed so much???

My tester is a Lamotte ColorQ Pro7.

Hi John,

You don't really want your chlorine to come down too quickly [:)]

Alkalinity varies with pH and from you changing results it will settle better as the pH goes up and chlorine lowers.  From your tester, what is the calcium hardness level?  As it's a new fill, knowing your tap water (assuming that's the source) figures for Alk and hardness would help to see where abouts you are pool wise before making any other recommendations.

Ta for the reply TP.. The water is tap water.

I checked the calcium hardness on the 26th June when the water first went in at 118ppm and then again on the 1st July at 108, but not since then. I just consentrated on the CF, PH and TA as I mentioned above. One of my worries is that if  chuck more cyanuric acid in it will drive the PH down further? I spoke to a guy from Chemigem on Friday morning and he told me to switch the system off when ading buffer or acid as the control system would try to control the chnge when it wasn't wanted. From the way the sulphuric acid bidon level had dropped he was right..

It is a tad frustrating as the water is crystal clear and 27ºC [:-))][:-))] but I am hesitant to get in a pool at a PH of 6.8 ?

Our Chemigem auto doser system gives me a PH reading of 7.4 and the chlor is a millivolt reading that should equate to about 2ppm. I have to contact C/gem in Aussy on Monday morning to see if their kit is reading wrong, or what???

Hi John,

Ok levels aren't bad, calcium hardness could be a little higher 150-200 add hardness + or calcium chloride.

You can raise your pH by aerating the water, point your returns skyward or slacken the lid of your prefilter so it draws in a little air to cause bubbles out of the returns and pH will rise but leave the others pretty much where they are.

Chemigem or any other units need the recalibration from time to time. if the probes were left dry during your re fit they can oxidise so give them a clean with the wife's toothbrush [:-))][:D] a bit of laundry detergent then try again. Re calibration is normal each season.

See how you get on.

The probe was changed just over a year ago. I kept the old probe and that was fitted into the pipe when the pool was drained. I then filled the cover that came with the new probe with water and put it back on the new probe while the pool was empty, so the probe didn't dry out at all.

Normally it isn't recalibrated at all, it isn't necessary. I think that this will be the exception though?

Ihave redirected the jets and will make sure that some air is injected into the pool after the British GP [:-))] [:-))] [B]

Joy of joys. All is well with the pool and the temp is now at 28ºC.

The chlor is still slightly high at 5.0, PH 7.2, TA at 114 and the cya acid is a bit low at 28, but now everything else is settled I will bring that up to 50ish..

The steps look and feel great too, well I think so [blink]

I have to admit that I was surprised at the blue of the water with a white liner. We think that it looks better than the blue liner I stripped out though.
