Temp Capping Off Water Pipe With Pics

[Tozzy]

Hi,

Just wondered if this >>>

would work as a temp cap on the copper pipe shown in the picture below?. It doesn't have to be soldered on right? Plumber has quoted me over £100 to take out the sink and temp cap off the supply pipes! So, I'm thinking of doing this myself. However, I don't want to solder on the stop end as it's not a permanent fitting, just buy a push fit type. What do you think? Would this be possible? It doesn't even matter if it leaks a little, i can just put a bucket underneath until the new sink is to be fitted.

This picture is the sink due for removal, showing the copper pipe in which cap is to be fitted:

Yes, no problem.
You'll need to wrap some ptfe on the tap connector or use a new fibre washer, by the look of it it's been leaking already!

or depending on if you plan on fitting flexi's if your fitting a mixer tap etc cut the pipe lower down and fit a pair of isolation valve.
personally i'd fit new tap connectors anyway looking at the condition of them.

Thanks very much guys for the quick replies.

Yes, no problem.

Yes, you're right, it'll definitely need a new washer putting in there, but I'll use ptfe tape first. It doesn't matter too much if it leaks though as the plumber will do the rest when the new sink is installed. However, if he's going to charge me an arm and a leg, I might attempt that myself too.

by the look of it it's been leaking already!

Actually, it's been leaking for many years (possibly 10-15 years!), but we have just never noticed it, until now , but luckily, it's going to be sorted.

Thanks for the tip there. Yea, I have been thinking about this. Seems a good opportunity to fit some isolation valves. Sorry, what are flexis? I do actually have the mixer tap for being fitted

By the way, please let me know only if you think that the pipe can only be capped here instead >>>

if it's a mixer you'll more likely find a pair of flexi's in the box

 

[Tozzy]

I see. Ok thanks I'll fit these too.

 

[Tozzy]

Sorry to be a pain, but the isolation valves have to be soldered don't they? I don't mind, suppose it's only a blow torch I'll need if so and that sticky bonding stuff, but the main worry is it's right next to the gas supply meter . Will it be safe do you think?

no compression fitting ball-o-fix valve
fit one end to pipe then screw flexi straight onto other end.
leaving off the compression nut/olive.

Smashing matey, you've been a great help. Have been looking at this too, it has the same model you're talking about too

Here it is, incase anyone else wishes to do the same work in the future:

Glad there's no soldering involved. Yea, I see how it works now, I think the body of the valve and the compression nuts keep the olives intact.

if your on gravity hot/cold supplies make sure you fit the full bore ones.

my mixer tap came with a set of hard tails to screw into it.. bloody things.. soft as hell copper too..

I don't know what a gravity supply would be and how would I check? And what is a full bore isolation valve? Please advise when you can. I'll be in here again tomorrow evening. Thanks

is your hot water supplied by a hot water cylinder with tanks in the loft or a combi boiler etc

hot water supplied by a hot water cylinder with tanks in the loft. Yea, definitely gravity fed central heating system. So, are there two different kinds of valve, full bore and something else?

 

[seco services]

a standard 15mm isolation ball o fix is only about 10mm bore inside
that will restrict gravity flow quite abit.

fit full bore 15mm isolation valves and the bore stays the same all the way through so no restriction.

look down the end of one in bq.
screwfix do full bore ones.

also check your new mixer is for low pressure not high.
