spanner size?

[proton]

Been trying all afternoon to change a tap, can't get the water pipe nut to unscrew, despite MD40 and useless special. tool from lazada. What would be the spanner size? got a 17 and that's not big enough

They do vary just to cause annoyance.

 

A decent sized adjustable is your friend.

 

They're always a nightmare, but you just need enough to break the seal (you will also probably need someone to hold the tap as by now it will be going round).

Got an adjustable, does not quite fit it

[digbeth]

22-25 but usually use vice grip as most socket set only goes to 19

Tell me about it!

 

You will also find that the larger adjustable won't fit under the sink!

 

At this point call a plumber and crack a beer!

Plumbers are as elusive as electricians in this country, so we're talking unicorn level.

Try a left handed hammer!

If you can, get a pair of vice grips onto the nut then twist the tap.

I generally use my son with a set of moe grips pn the nut while I hold the tap. I can get down to do the job but I still need somebody else to hold the tap and get me up afterwards.

 

I am 78 and my son is 18. Technology transfer and grunt work training skills at play.

No chance they want 1500 baht just to turn up, Mrs would rather not use the tap!

Got one but not big enough to go round the nut, might have to get a bigger one

BUT.

 

You will get a continual ear-bending about the non-functioning tap.

 

Sooo, is it a. No nookie or b. Pay the man?

As sometimewoodworker said above what you need is a basin wrench. ประแจขันน็อตใต้อ่าง

 

This is the type I've used in the US. You can research the part number stanley basin wrench 87-448 and see if its what you need. I saw one site saying its 22mm. You can check out the reviews on Lazada that show some pictures of it.

Another style that has quite a few reviews but more expensive:

22mm is slightly too large, but if you don’t need it really tight then it’s OK

At your DIY store, you can buy a replacement hose with a plastic floating/sliding finger spanner on it, cheap as chips, buy 2. 

 

The first one cut an end off to get the plastic finger spanner. Then cut the end off the one you want to remove.

 

Slide the finger spanner up the hose you want to remove and see if it will undo with your fingers, if not, get about 12" of 1" plastic water pipe, cut slots in one end of the pipe, so the ears on the plastic spanner fits in it, now slide the pipe up the hose to locate the ears on the spanner and turn the pipe, if still tight glue a 90* on the other end of the pipe, job done.

 

If you want to replace that plastic tap nut, cut more slots in the pipe to undo it, use it to tighten the new one...

This one that Shopee sells looks pretty good after watching the video. At the end he shows three different options to buy depending on what you need. The Shopee one I linked to doesn't include the attachments but is cheaper if you don't need them.

I still have some metric spanners from a previous life that I cut in half with an angle grinder tp dp\o some tight fit jobs,

 

Back then of course, I would simply buy another one and invoice it.

Ok if all else don't work.

Undo the white plastic nut,( jam the tap above first to stop movement. )

Pull tap up, cut tap around thread area. with hacksaw.

The rest should be easy.

Interesting what the "what else might interest you" suggestions came with that when I clicked on it.  Tells a sad, frustrating story of squeezing under the sink to replace a tap, leading to broken bones, and ending up howling at the moon while ripping peoples throats out...

Been there and done that.

 

Now I have an apprentice until he goes to uni in May.

 

The worst case situation.

 

I may have to train 'er indoors.

I recently replaced 3 faucet sets (two nuts each).  One more to go. I think I managed to loosen  the nuts using the tips of the Vise Grip jaws.  What pain!  Mine were inside a vanity cabinet in a very tight space - had to lay on my back in there. Not looking forward to replacing the last one.

[liddelljohn]

usually 22 mm  bur not easy to get at , can use crows foot extensions  and a ratchet for access if really awkward

[Dante99]

I use a pair of pliers.  It is not a highly torqued joint, actually hand tightening is usually sufficient for those joints with a rubber washer.

try MOLE GRIPS

Maybe cross threaded then forced the rest of the way on.
