  • Sealing up a stopcock – permanently
  • Kryton57
    Full Member

    After our new kitchen is installed, our indoor stopcock will be behind the unit that’ll house the oven which is at chest height. There will be a non visible hatch to allow me to turn it by hand. However this year (different kitchen arrangement) it leaked, need a replacement tap.

    If this were to happen after the kitchen was in stalled the oven & cupboard would have to come out for the fix, and if it leaked badly would be affected / ruined by the water. It can’t be relocated as below and to the exterior is a cast iron pipe, above it the brass pipe is buried in the plaster.

    So is there a solution such as spraying the whole thing in a kind of waterproof expanding foam and sealing it up (we still be able to turn the water off from outside)?

    Or, what else to remove my paranoia for the next few years?

    water regs require a stop valve to be located either inside the building or immediately outside the building. The stop valve at the boundary doesnt suffice.

    yes seal it with some water proof in the event of a water leak there or in your house you will be glad you did this 😯

    FWIW you can easily relocate the tap point by simply using pipe from it to a suitable and convenient location- i assume something other than just the handle is poking out

    If not you need to dig it out as there is a reason we have internal stop cocks for our water supply.
    ITs copper not brass FWIW

    Junkyard, there is nothing between the external mains stopcock and the internal one, so using the external one would make no difference to the outcome.

    Yes the whole unit is sticking out with the the entire cast iron pipe below, and the copper (sorry) pipe having about 1″ exposed before it goes under the plaster. We’d have to dig out about 3 ft (upward toward the ceiling following the pipe) of plaster wall to dig it out. But maybe it’s a job worth doing?

    Good news then both the inside of your house and the outside are in the same location and you can access them bith just as easily from the inside of your house.

    You ask for advice you get it then you a disagree with it

    In that case spray it with expanding foam and everything will be fine,
    as neither sense nor building regs make any difference.

    HTH.

    so using the external one would make no difference to the outcome.

    except it’s a long way away when you are in a panic and a pipe is pissing water everywhere, not to mention, do you need a special tool to open the valve box, is it accessible by hand and if so is it able to be isolated by hand or is a valve key needed?

    The stop cock in the house (or right outside the house, easily accessible, hand-operated) is there for the householder. The one at the boundary is more likely to be used by the water undertaker or contractor.

    I think you’ve missed the point, no need to get upset JY.

    When installed, the stopcock will be behind a cupboard, and behind a cooker – accessible for me to turn it by hand. My issue is if it leaks – in which case I’d need to turn it off outside anyway (which is accessible by hand and is now a modern plastic quarter turn-by-hand handle btw).

    So, seeing as I can turn of the mains outside in about 20 second assuming the front door isn’t locked, it wouldn’t matter if I stopped it pissing water over the back of our new oven / kitchen units would it?

    while you have the perfect chance to fix something properly why bodge it again and live worrying it may fail?

    Hmmm so you wont move it – you want to stick it behind immovable things and you want to smother it in waterproof shit so by the time you know of a leak its too late ?

    All fair points – if the best advice is to dig the pipe out of the plaster while the Kitchen is back to bare walls (it’s being redecoraerated and skimmed anyway), that’s what I’ll do.

    It’ll be about 8ft up above a cupboard though.

    Id suggest a stopcock leaking is a very rare occurence, so id still want one in my house under my control.

    I assume the outside one is under a cover in the street as per most houses? [This was the case for my parents and when we needed to turn the water off in the street to move the stopcock we found it wasnt actually there, the council had re-laid the path and not aligned the cover with the pipe down to the valve, so we had to pull up slabs to find it and dig the sand out to access].

    As above. Relocate it and put it somewhere sensible and accessible. It’ll save pain in the long run.

    Stato yes, it’s just been renewed as I discover that I couldn’t turn off the water when the stopcock leaked a month or so ago.

    JU, it can’t go down at the pipe into the house to about waist height is cast iron. It can only go up above the cooker, or on the next floor in my daughters room, where there is already another stopcock.

    The idea is to prevent it ruining the cooker if it leaks, which it would do anyway if it was above it, but at least above it it’s accessible with a spanner, whereby it won’t be without removing the cooker.

    … or get it done properly, and relocate it somewhere sensible, like the cupboard under the sink.

    I could understand you not wanting to do this if the kitchen was newly installed, but see no reason whatsoever not to do the job properly if the kitchen is being totally gutted anyway.

    It may be easy or it may be hard but it really can go wherever you want to put it.I would go with the other sensible locations rather than the ones you seem determined to implement

    How can I put this? The Mains – cast iron – pipe comes from the front of the house, under the hall/stairs under a nice floor whihc DD installed, I under the kitchen floor then up, out at the back of the kitchen, up through an upstairs bedroom into the loft, across the loft, back down by the boiler (located upstairs in a cupboard and then from there it Spurs across to the bathroom, down stairs to the sink/ washing machine point.

    So where it is is BEFORE everything other than the hallway. To relocate it would be after something. And as I mentioned there is another stopcock about 10 ft away vertically in the upstairs bedroom, and yet another in the loft before it enter the boiler cupboard. So there’s nowhere for it to go of any benefit, apart from up higher slightly to get away from behind the cooker.

    Where does the cast pipe stop and the copper start ?

    Wherever that is, that’s where you work from.

    Install a copper pipe from that point, to wherever you want the stopcock. Then reinstate the feed from the stopcock to the rest of the house.

    About waist height up the kitchen wall in the corner – the stopcock is immediately after it. The original plan was to lower it to floor level – becuase then it would be behind a removable pan drawer giving good spanner access – but 4 of 4 builders won’t cut the cast iron pipe.

    Can you not remove stopcock. From there pipe to where ever you want the stopcock and then re-pipe back to where the stopcock was?

    So – you have in internal stopcock immediately above the kitchen? Why not just remove the one in the kitchen and replace it with pipe?

    Presumably a threaded male iron thread into a brass stopcock, then compression to copper?
    In which case I’d be inclined to leave it as its no more or less likely to play up than any other copper to iron fitting you replace it with. Maybe re-do the packing gland around the spindle?

    I’m not sure what you mean by compression but yes one end is on the cast iron the other is the copper pipe – immediately on he join here is where is starts to be plastered over. . By gland and spindle I’m guessing to mean the tap bit that I would turn – this was replaced by the plumber when he came as it was this that was leaking. I can see it has that white thin plumbers tape wrapped around it.

    I guess I’ll leave it, hope for the best and if it all goes pear shaped and water pisses all over the back of the cooker then that’s what house insurance is for.

    contact your water supplier and see how much it is to have your supply pipe changed to a nice blue one – should be subsidised you may be surprised at the cost.

    Whilst you’re building etc get the pipe changed you wouldn’t want that cast iron pipe to crack and leak ! Its probably as old as the house.

    This will solve the issue

    In for a penny out for a pound !

    You do realise that if your incoming main is in cast iron that this is more likely to fracture than your stopcock fail again?

    Are you sure it’s CI? It’d be unusual (well up here it would!), more likely to be lead…

    I’d be tempted to get it done properly (and not on plastic push fit neither, they can pop olives and be a complete disaster). Copper with potable capillary fittings (yeah, by a plumber).

    Photos might help.

    What’s the point of asking for advice, getting it, then ignoring it all ?

    Seems an odd way to go about solving a problem.

    Its a victorian property built in 1906, so it probably is.

    id be on the phone to the water board to check out your pipes ! nice blue one fitted free of charge ! but tbh I doubt you have lead pipes running into your house it should have been changed at some point …good luck fella

    That looks very much like a lead-loc fitting in the picture.

    Could do with a better picture though.

    If you scrape the pipe with a sharp penknife blade does it make a mark (lead) or not (iron)

    Unfitgeezer I doubt they’d pay for the removal and reinstatement of my floor, stairs, kitchen floor and units.

    Reading the safety advise, it’s lucky the water based first activity is a shower in the morning then to remove the water sat in the pipe overnight.

    I’ll try to get a better picture tomorrow without using an iPad.

    It was standard practice to use lead as it was malleable and not prone to fracturing (remember this was pre central heating so pipe liable to freeze. CI would fracture/shatter if water froze internally).

    Lead really not great for health. Councils used to give you replacement grants, doubt they do now though.

    I’d be looking to get a new incoming supply – speak to you water company, ask for quote. They might have a scheme. Not sure how things work in England I’m afraid.
