So better go with electric heating - safer and better.

Not so fast Sir. They show the cost per unit of Electricity as Rs.5. Where I live the cost is Rs.8 or for heavy users it is Rs.9.

True. But if you compare unsubsidized gas heating against electric heating, the costs are quite similar. (even with the higher rates per KWH). Then there is the safety and convenience factor too.

My peak rate also goes upto Rs.8 + surcharges = Rs.10.5

I could be mistaken. Apparently gas geysers have an efficiency of 85%, unlike heating water on a gas stove. Also, a gas geyser has the equivalent of a 12 KW heating element, so it is able to perform better as an instant geyser.

I'm not sure about the 85% efficiency, more knowledgeable TBHPians can chime in, but I'm more inclined to believe the 61% energy factor used in the energy calculator below.

Hi Guys,

Bit of a noob question.

I have to carry out basic repairs on a cracked Sintex plastic water tank.
I have been told to buy and use a glue gun as it's the cheapest option.
Can anyone suggest a good hot glue gun with on/off switch and temperature control in the region of Rs. 1000-1500 or so.
There are so many on Amazon with conflicting reviews that I am confused.
If someone has actually used one of these guns and has genuine feedback it would be much appreciated.

Many Thanks,
SS

Don't go for glue gun for repairing plastic water tank. I bought Stanley glue gun a long time ago for mending odd jobs. But I found them almost useless except for fixing small items. I had to switch to JB Weld for all my repair jobs - from fixing broken ORVM to broken cutting board.

Before repairing the tank
. If the crack is due to age and UV degradation, then repairing one area will not do as the rest of the tank may degrade and crack with time.

. If the crack is due to impact or other mechanical issue, then it is fine.

To repair tanks, the preferred method is as follows

1. Clean the tank surface around the crack.
2. Cut a piece of thick plastic sheet. It should overlap the crack by about 10 cm all round.
3. Use waterproof glue or heat gun to stick the plastic to the inside surface
of the tank.
4. The sheet should be flush with the tank with no air pockets.
5. Once the "patch" dries put another patch that is slightly larger than the previous one.

Now unless there is mechanical stirring or poking, the patch will hold. As it is inside the tank, water pressure will push it against the crack, so there will be no leaks.

Using Hot Gun to melt material is risky as it will weaken the tank to the extent that it will leak or in worst case burst.

I agree with Prowler. Hot glue does not seem to have much adhesive strength. Also, you can never be sure about the quality of the glue stick, apparently Stanley is the best according to the "Project Farm" YouTube channel. Also, hot glue does not flow well. I think these are best suited to craft activities, or maybe I just don't know how to use this tool right.

Thanks @Prowler, @Aroy & @mvadg,

It looks like my doubts have been confirmed. After reading your posts the glue gun plan is cancelled!!

I was also hesitant about buying this glue gun which would probably end up as another piece of junk in an already overflowing "Spare Parts" cupboard.

I think it's better to call a professional tank repair guy and pay him the 1500 that would otherwise be wasted on glue gun and sticks.

Thanks once again,
SS

One suggestion to SS: See if you can do this patching both on inside and outside.

Plastic welding is a thing, and not that difficult. Apparently it was more prevalent in India a few years ago before we caught up with the throw-away west.

You can find videos on plastic welding on youtube. Be aware that it produces lethal fumes. One would certainly not want to be inside a tank doing it --- although it wouldn't surprise me if that is what your Rs1500 man will do . Anyway, call the pro: it's not the kind of thing to be your first try.

If I had to DIY this, I'd turn the crack into a hole, and use, eg, M-Seal putty on inside and out. I'd also consider the age and general condition of the tank and think about replacing it instead of repair. But then, I come from the throw-away West!

(Actually, I get great satisfaction from mending something, even a cheap thing, if I can)

The glue gun will not hold the leak due to water pressure in the tank.
For proper fix you can get a ready-made patch for fixing plastic tanks and pipes at a local hardware store. It's built for the purpose. Sand the surface using a heavy grit sand paper, apply some Araldite, heat the patch and fix it from inside the tank. You can also apply some Araldite and m-seal from outside for good measure.
We did the same during the weekend to our tank and it fixed the leak. Fingers crossed.

Reliance Retail has acquired the rights to manufacture BPL & Kelvinator consumer products. Both were iconic brands once upon a time. Guess all of us have had atleast one product of either brand in our house once!

P.s. BPL had come out with a massive ad in Times of India Mumbai yesterday, was pleasantly surprised to see that.

Amazing. Here we are, beating our heads at DIY innovation, and it turns out that there is a purpose-made product! Many thanks for letting us know
