My Basic / Silly / Moronic Questions Thread

[WaterTight]

None of these justify a thread so I'll keep them in the naughty corner

1. You know when some of the jets on a shower head come out at a random angle so you lose full coverage when you stand under it and maybe get an eyefull when you turn it on? What causes that and how would you fix it? Is it similar in cause to the jets on drinking fountains which seem prone to go mental before long?

2. Temp earth continuity bonding. Do you guys actually use it? And are you meant to use it when breaking any run of metal pipe i.e. even undoing a fitting
to remove a tap?

3. If a stopcock or gate valve is really seized, how safe are you generally (speaking from your experience) to wd40 it and give it some serious welly with a tool for leverage or are you running a real risk?







Stay tuned for more...

1/limescale remedy clean it or get water softener
2/continuity bond is for when breaking into a gas pipe/fitting
3/giving it some serious welly is asking for a flood

sorry water tight I am bored today as this is the first day I have had off for 4 weeks, but I aint that bored that I am willing to answer these questions.
these questions are way beyond needing any form of training to answer them, therefore I suggest you look at your questions and try your figure out the answers for yourself, then post what you think, the answer should be, and we can tell you if your right or wrong if we feel like it.
By the way way I am not getting snotty or arsy, I just think you should use some of the common sense you were born with
regards
Mike

My electrician told me there is no need to supplimentary bond anymore as of 17th edition. ?? any sparks on here?

That’s quite right if electrical installation is to current standards
Infact many think it is dangerous as it lulls people into a false sense of security

Not strictly true.

A test must be carried out between pipework and earth.

If this proves ok, then ALL circuits in the bathroom must be RCD protected.

If the above are met then there is no need to supplementary bond between pipes.

ive learnt something. and on a sunday !
cheers jason.

whenever someone feels the need to say they are not getting arsey it's because they are
it's like starting a sentence with "no offence but..."
But yeah, i'm bored too, it's mainly why I wrote the thread. I suspected the answer to the first one but doubted it because the other day all of the showers in my gym simultaneously had developed the same prob. So I thought cocked up maintenance might have caused it.

The second one was more a case of wondering how much people actually bothered with it because I got the impression at college nobody did.

And as for the third I was fishing for stories to see how much people had or hadn't got away with. But yeah, they were stupid questions really. I only wish I'd indicated that in the title.

i bond the pipes by holding on to both while working on the fitting with the other. tehe.

 

[Smcart5]

Has anyone gotten a shock off pipework where eath continuity is not complete?

 

[bobpape]

All of your questions are valid,
One way of cleaning the holes in a shower spray head is take it to pieces and attack the
spray holes with a nail brush,

It is common to get an electric shock from any pipe that has an earth attached to it,
So it would be wise to use a temporary bond, I have measured 110v ac on a lead
water main of which I had just cut a section out, I traced the fault to crossed meter
tails,

I allways use heat to free up a siezed valve, even when full of water it still gets hot
enough,

 

[Mike Jackson]

One of our guys got 400v off a gas pipe the other day.

 

[Smcart5]

Is he still alive? i thought 240v is deadly..

 

[secret squirrel]

although volts is obviously no good for you and you shouldn't make a habbit of getting shocks it is the amps that do the damage.

I am unsure and quite happy to be corrected but I think we can feel as little as 0.1 amp and it doesn't take loads of amps to kill.

 

[Jason.S]

Thats why RCD's are rated at 30mA.

 

[andekoch]

generally below 50 volts is regarded as safe that is why site tools used to be (new elec regs allow you to use 230V tools on a construction site as long as there is a 30mA RCD on the supply) 110V (fed from a centre tap transformer so it was actually -55V on the one side and +55 on the other giving the tool 110V).

I always check the voltage between pipes when starting a job and often put a fly lead on before cutting (clamp either side of where cutting)
