Adequate insulation on pipes?


I have started to put insulation on my pipes down in the basement. Before I got too far, I wanted to see if I was doing it properly.

The pipes in the picture are the hot and cold water pipes from my water heater. I used PE foam insulation, and put it all together with some silver tape.

Am I doing it right?



For comparison, here are the pipes before insulation:

That's fine but why are you doing it?
If the basement is above 32 deg. you do not need it.
They sell 90 deg. foam elbows so you do need all that foil tape.

Adequate insulation on pipes?


Well I read that it's good anyway on hot water pipes for energy savings (cold air can lower temp. in hot pipe as it travels to the faucet. On cold pipes it can help keep the pipe from getting condensation (or so I read in another thread on here).

Another reason is, even though I may not need it as much (though it can get pretty cold in Massachusetts in the winter) but just for the experience of doing it. I'm a first time homeowner trying to learn as I go.

Thanks for the tip about the elbow pieces. I'll keep an eye open.

In my experience duct and electrical tape will fail after a few years. I'd stick with the foil tape. Who cares how it looks (as long as it's workmanlike), it's a basement....

you have to use good electrical tape like 3m super33,not that 35 cents a roll jap wrap tape!
if you think that and the ul 181 tape on the water heater flue pipe look like good workmanship,might i suggest going to work for somebody as an apprentice till you learn a little more about quality work?
if youre going to put your name on something,i dont care if its a piece of pipe 20' underground make it look likeits the best work youve ever done or dont do it.

Are you referring to the work I did in the picture?
I never said it was good workmanship, I was asking for feedback! A little constructive criticism might be better.

Oh, I'm sorry for misreading.

Is that bad workmanship, though, the foil tape on my water heater flue (bottom of the second picture)? Is there anything I can change to improve it? Thanks, and sorry again for misunderstanding

that flue pipe should have screws holding it together,if it has holes in the pipe it should be replaced not taped up

Oh, boy.

Should I try taking off a piece of tape and see what's going on under there, or should I call someone instead?

id just peel the tape off and put 3 sheetmetal screws in each joint if they arent already there,if theres big gaps in the pipe joints go ahead and replace it.
its pretty simple to do with a set of snips and a drill

I think we have different definitions of "workmanlike." I use it to mean functional , to code, and tidy. Personal aesthetic preference (silver vs. black) is not part of my definition. Personally, I think using electrical tape looks pretty hack. And I made no comment on the OP's photos-- my statement was made generally.
