Hi Guys, apologies for probably sounding clueless and all that but would really appreciate some advice before I take on my first tap replacement. I am currently training for my C&G 6129 and am attempting to get out there and gain a bit of "Hands on" experience. I have been asked by a friend if I could replace their kitchen tap. They have purchased a "Bristan Echo Sink mixer" ?? I have been over to size the job up and all looks FAIRLY good. (Appreciate these are the words of death). The current taps are very similar, both have the copper connectors that are "Tapered" (I would say from 15mm to 10mm). My problem is that I don't really trust my soldering skills enough to do it the professional way so am interested to know if it would be acceptable to use the flexi connectors? Reading other posts, I am lead to believe most of you guys don't really like these, especially the push-fit ones. However, I would be inclined to go for compression (feels and looks stronger). Firstly, is this allowed? Secondly, would they reduce the working mechanism of the mixer tap?

My plan was to cut the pipe back from the existing connectors,(once isolated water supply), remove old tap, replace with new, with flexi connectors tightened (Hand tight?), Secure with fixing rod and nut and then connect to pipes. Isolation valves are already in situ further along the pipe so plenty of pipe to use. Am I right in thinking the compression fittings will need olives?

Many thanks in advance for any help as I attempt to breach the big wide world of plumbing! 😕
 
1. We all had to start somewhere so no need to apologise - when I started I kept saying sorry everytime I asked something and in the end was told not to keep doing this.

2. Use whichever method you're most comfortable with and next time you're in a training session, ask them. They're being paid to teach you things like this.

3. Generally, it's best to use whatever comes with the tap and the connections need to be a little tighter than hand tight (but not over tightened.) If these taps have copper connectors then use (in order of preference) soldered fittings, compression or push fit. If there is no isolation valve then it's always a good idea to fit isolation valves to the bottom of the tail pipes so if the tap is faulty (or the customer wants to change their mind after a year or two) it's an easy change. (You can use isolation valves as a compression fitting.)

If the tap connectors are flexible lines then I use a compression nut to fit these to a small piece of copper pipe and then fit an isolation valve. Others fit them directly to an isolation valve.

Take your time to make the job neat and good luck with it!!
 
Many thanks for your rapid response to my problems, and thanks for understanding the newbee. I have just bought my own blowtorch to practice my soldering as want to do things the correct way so feel practice will make perfect!? Hopefully! As for the current job I will prob use the flexis. Isolation valves are further along the pipe so would be hoping to fit the connectors to the pipe, then pipe will go to isolation valve. Am guessing the compression nut you talk of will come supplied with the flexi connector? Any other "Bits" I would need??

Thanks once again!
 
Other bits ... some ptfe tape if it doesn't work first time.

Some of us use a compound as well - there's a thread on these if you want to find what we all use as we have our favourites.

Decent wrench and pump pliers. You'll be fed up with cheap ones after a week or so. Tape measure, pencil, spirit level, screwdrivers, towels ... there are a few threads on these as well.

Oh - and a van to keep the clobber.
 
Thanks guys for your advice, just one thing, if the flexi connectors don't reach fully to the actual 15mm copper pipe that is in situ, would the compression fitting of the flexi fit on to the thickest part of the original copper tails from the old tap? Say if I was to slice the widest part of the tapered end before it goes into the existing elbow? Then connect the above mentioned product up to the tap? (Obviously connecting the tap end first).

Thanks once again, you have definitely made me feel more confident.
 
The old tap tails, if done correctly, should have compression fittings on them. If not just cut the pipes no lower than 250 from the sink top. That will give you 2" or so to play with. You can always cut them again if you like but if you cut them too short you will need to extend them.
Don't use additional flexis or it will look like a dog pyshin in the snow.
 
but word of warning as i first found out,, if you ever decide to cut the supplied tap tails the 15mm-10mm ones you were talking about do it slowly with a manual cutter not a pipe slice as these will quite often bend out of shape with it being really soft
 
Belt and braces make sure you have got a couple of isolating valves to spare as the ones that you use to isolate are bound to leak from the stem once you operate them
 
A dog pyshin in the snow!? Doesn't sound like the sort of workmanship I want to be associated with. The current tails screw in to the tap one end and then are soldered into an elbow, then runs straight to the isolation valve which is a good distance along (400mm)? The new tap connectors are approx 250mm so I am thinking I may either need to slice the pipe between elbow and isolation valve, or before the elbow, thus attaching the flexi on to the widest part of the existing tail, before it goes in to the elbow. All depending on what length I have to play with (no jokes please)! Wouldn't ever use more than one flexi joined to another!

I looked on screwfix as you suggested, they state it should be used with check valve??? Also, would you suggest needing to use any compounds or plumber's mait to secure tap to sink? I've never really understood whether you should use anything more than the washers and backnuts they supply with any kind of taps, kitchen,basin or bath?

Many thanks once again for all the help and advice!
 
A junior hacksaw is better
I beg to differ.Everyone has their own preferances i know but I once had a tap tail that was so soft i bent it using a juniour hacksaw from the pressure of the blade, a manual cutter, small turns, slow and steady wins the race 🙂

It won't look good if you have copper pipe, flexi then copper pipe.

So in this case you need to alter things accordingly and use your new found soldering skills!!

Re-attaching tap to sink, just follow the instructions. If you don't and a warranty claim needs to be made if they find anything not according to instructions they won't pay (this applies to boilers and all sorts).

And manufacturer's are usually happy to answer queries.
 

When did they start making them?😉

Everyone to their own. Tap tails are all soft. Learn to work your junior better and use a decent blade.

a very good post. never a wiser word said.. thats one of the first things i learnt.

Sorry, think I have given the wrong impression. Wasn't going to use copper-flexi-copper. I was just thinking that if the flexi doesn't reach to the actual copper pipe for connection then would I be able to run flexi from the tap, down and connect to the wide part of the existing tail. Almost like treating the wide part of the tail as a normal piece of 15mm copper pipe? Apologies if I'm not being clear, just not quite up to speed with the lingo and thought process of you pro's. Hopefully one day!?

In general would you use any compounds or silicone to make good with taps?

Thanks once again though!
 
What fittings have you got that fit into the tap? Copper tails (usually 10mm increasing to 15mm) or flexible tap connectors (usually 300mm lengths of hose)?

Generally no need to use compounds on the taps as they have washers to do this for you. The compounds I was talking about are used in compression fittings.
 
Could you not get a plumber to guide you to change a tap as I am sure with various posts it can seem quite daunting if you are not sure how to do it
