college

[jwkidd90]

Hi all,

I'm hopefully starting a college course in September and have been asked to do an assignment as part of the interview. As I am going to college straight from school I have no experience in plumbing whatsoever. Any help or pointers would be very much appreciated.

The assignment is as follows,

Exercise

Friends of your family have asked you to a small plumbing job for them that involves the fitting of an outside garden tap. They are keen that you treat the whole job in a professional manner and calculate and quote the price, as a professional plumber would do.

The outside tap is to be fitted immediately through the wall from the kitchen sink and connected to the cold water supply in a 15mm copper tube. The special tap and all other fittings that you need can be found in most DIY stores and local suppliers.

You will need to :-

List the materials and fittings that you will need

Produce a neat sketch of the finished system

Write a numbered step by step list of how you would complete the task

Include what tools you would use


The family friends have asked you to write a letter :-

Detailing the date and time you intend to do the work

How long it will take

How the work will affect them

How much it will cost them. The total amount should include the cost of materials and fitting plus an additional 25% for travelling, tools wear and tear and your profit.


Well that's the assignment, I know it's abit cheeky asking here but as I stated I am totally new to plumbing and have chosen it as a career choice due to the lack of trademen in the UK. Once again thankyou in advance for any help or advice/pointers given they are appreciated.

JW.

First thing is get to your library and see if you can borrow a text book. Failing that have a look for DIY guides on the net. See if you can work out from there what you need. Go online to NoLinkingToThis - Power Tools, Electrical, Plumbing Supplies & more and you should then find all the materials.

Once you've done that then we'll give you some advice. I don't mind helping but you've got to make the effort yourself first.

Thanks for the input, so far I've come up with this with the help of some guides on the net, the artwork is mine using paint on the pc.



Items needed :-

PTFE tape
Jointing compound
15mm back plate elbow
outside tap
A 15mm isolation or gate valve
A 15mm equal tee fitting
15mm 90 degree elbow
15mm copper piping
15mm drain cock
wall clips
small piece of 22mm copper pipe

Task :-
1 - After turning off the water supply, I've inserted a T-fitting into the cold water pipe leading into the kitchen, I've done this by cutting the pipe making sure the cut is square and cleaning both ends smooth with wire wool. After fitting the T-pipe I've fitted an isolation valve, this will enable the supply to the outside tap to be turned off during cold weather to prevent freezing and enable me to continue the work with the water supply turned on.

2 - Next I've fitted a drain cock, this isn't necessary but will give the opportunity to drain water from the tap during cold weather again to prevent freezing.

3 - After I've marked up the position on the wall where the pipe will go through I've drilled through using a 22mm masonary drill bit. Next I've inserted a piece of 22mm copper pipe as a sleeve for the 15mm copper pipe to go through. By doing this the sleeve is acting as protection from the surrounding masonary.

4 - After I've fitted a 90 degree elbow to the 15mm copper pipe I've added some more 15mm copper pipe to go to the required height, I've added wall clips to keep in place.

5 - Next I've fitted the back plate to the 15mm pipe by means of compression and secured to the wall, the tap is simply screwed into the back plate.

Tools needed :-
A small hacksaw
Adjustable spanners
6mm masonary drill bit
screwdrivers
A heavy-duty power drill
A 22mm masonary bit
Pencil and measuring tape
wire wool

you need to have a double check valve and a plastic fitting inline befor it goes outside
