Water line insulation

Installed a new well head cover and needed insulation for the existing water line and well head connection.

Very Good top liner for a waterbed, though quilted, does let the coolness of the water through.

Recommended by the guy that rodded out my lines last time.  Twice a year and do it when
you are leaving town for a day or two so it can foam up and kill for days.  Seems to have
prevented issues for me for three years now.

I swear by the function and insulation value both heat and cold are diminished by a great amount. without documenting the test and r values and btu's saved or lost. the next step would be ridgid foam board insulation covered in aluminum reflective coating.

These little gaskets seem to work fairly well. They won't prevent water from reaching the electrical current, but they do provide an effective barrier. It's still much better to seal off your electrical connections as a guaranty that no shocks or shorting occur, but these complement such a configuration.

I love this bladder insulator - it covers and protects my Cablebak perfectly. The water stays cool for hours.

Don't forget the Mineral or Vegetable Oil when installing !!!!!

Splice wires High Above Bilge Water Line.

SEAL any splices/solder connections with a Liquid Tape Product.

does the job  only issue water gets in and you can't see the panel  needs sealant

Bought this to waterproof a cable line I accidentally cut. It's been a month or two now and we've had several rainstorms that have completely soaked that area of the yard and I've had a consistent cable signal after the repair.

I bought two of these in different lengths to hopefully keep outside lengths of potable water hose from freezing. One hose runs from an outside hose bib on my house into a valve which feeds an underground PEX run. The other hose connects the PEX where it comes out of the ground into a travel trailer city water inlet. The travel trailer sees winter use so I wanted to keep the water flowing. I live in Fayetteville NC so bitter bouts of cold are not typical here but there are times when the outside temperature will not get above freezing for a few days.

I attached this product to my hoses using a specialized heating cable application tape (<a data-hook="product-link-linked" class="a-link-normal" href="/Easy-Heat-HCA-30-Foot-by-1-2-Inch-Cold-Weather-Valve-and-Pipe-Heating-Cable-Application-Tape/dp/B002YF368C/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Easy Heat HCA 30-Foot by 1/2-Inch Cold Weather Valve and Pipe Heating Cable Application Tape</a>) which I bought here on Amazon. I then wrapped the hoses and heating cable with self sealing outdoor rated foam rubber insulation (like foam noodles that people use in pools but these are rated for outdoor pipe insulation).

The plug ends of these cables have what I'm guessing is a small neon bulb that lights to indicate that the system has power applied. This is a useful benefit to visually verify that power is applied to the system. I find this feature very valuable, although I didn't think much of it when I was purchasing these items.

The past couple of weeks have been exceptionally cold (for my location). Low temperatures at night have been below 20F and there have been a few days where the high temperature has not approached freezing. I have to say that these things work. The travel trailer had continuous flowing water through the hoses that are heated with this product. The travel trailer has a propane furnace that keeps the baseline temperature comfortable so the interior PEX plumbing is not an issue. For the outdoor supply lines though, these are working well.

I have seen questions as to whether these products can be used with flexible hoses such as garden hoses instead of only being useful for copper, PVC, CPVC, etc. So far, the products have presented no problem with the application on the water hoses. As other reviews and questions mention, my hoses are always water filled.

Great switch . this one will be used to keep my water pipes from freezing . Heat tape will not have to use power constantly.

Used for portable air conditioner while waiting to have central AC replaced.  Made a huge difference in the efficiency of the portable units.  Without the insulation it seemed like the portable units were just working against themselves.

The one star off is for difficulty in wrapping the exhaust hose in the insulation.  I think this product would be better if they had an adhesive strip along one edge of it so that it could stick to itself while wrapping the hose.  I would have happily paid double what this cost if it had that feature.

Good quality wire and insulation. Was a pleasure to work with. Was a bit longer than the specified 50 feet. Nothing bad to say.

Product works as intended. I used tape in the water line connection. You have to careful when instaling not to cross thread the plastic piece that attaches to the water supply. The filters trap a lot of particles and are easy to change.

Bought this to seal a plastiv birdbath that had begun to crack after many years.  I applied several thin coats over a day and it's been full of water again for a few months now with no leaks!

Taking precautions against heat damage advised by other commentators, I installed this with soldering. It has worked well in preventing water hammer from my dishwasher. I would purchase from this company again.

When you skin this wire you don't cut halt the wire away. The strands are thick. So is the insulation.
