someone has made a comment on my youtube channel that, the reason that the stoptap should be in the direction of the arrow is because, It keeps the spindle out of the pressure side making it less likely to leak at the gland nut,, Is that the reason for the arrow ?,  |

Tom it will be interesting if anyone enlightens us further on the stop tap jumper front but I find the drain down valves jumpers, still come as a two part item, do you find that common? Finally, Who's else has noticed Tom's personalised Brewcabin Cups on the shelf? |

I always ask myself does this make sense and do the pieces of the (puzzle?) fit together easily? If they do then that's usually the best answer. I don't really know if there is an answer to this one - I think we'll just have to settle on what we personally think the reason is . It would be very interesting to hear what the manufacturers say about it themselves though. |

how did you get that jumper out tappy, I tried pulling,then unscrewing and a bit of levering but could not get it out,  It's another old trick and I'm not sure if you're testing me on this one  Works 90% of the time. Unscrew the spindle Place a pair of pliers between the jumper and the stop tap bottom. Turn the stop tap back so the pliers are locked in place between the bottom of the stop tap and the jumper Hold the stop tap with a pair of grips in your left hand. Turn the stop tap anti clockwise with the handle with your right hand. As you turn the stop tap the pliers will start to push the jumper out of the body and after a few turns.. Hey presto, the jumper (should) fall out!! Thinks....I could do another video? Tappy, |

No tappy its a genuine question, in all my life I've never took the jumper out of a stop tap, I've changed many in hot taps ( loose jumpers) but never a fixed one,  |

I think that it was quite well known amongst the older generation of plumbers tom. Then again at almost 62, I guess that I'm now fast becoming one of those OG plumbers ! |

must be one of those bits of info slipped through my net, Probably an old council plumber who mended taps every day would know it, Come to think of it, I'd just change a washer, if the jumper would not come out, it went back in with a new washer on, |

I heard off someone years ago (maybe a forum) about the loose jumper in a stop tap being intentional, I've never figured out why you sometimes get loose jumpers in normal taps though, if I come across one I'll deform it a bit so it's not loose any more. I'd understand it on an outside tap for regs but not on a basin/kitchen tap, it's just a chance for getting water hammer and doesn't serve any purpose I can think of. Unless the house was chest high in water it wouldn't be needed to prevent back flow, and by that point no-one's turning any taps on  Probably only changed 10 jumpers in all my time and that's usually only when the thread's gone on the bit that holds the washer. |

Hi all, just returning to this post and there is some interesting reading. Thanks for all the input and thanks to Tom and crowsfoot for the recent vid going further into it. I Haven`t changed my stoptap or fitted the outside taps yet due to life getting in the way. I have checked the flowrate of the existing outside tap and was getting 13-14 liters per minute which I don`t think is bad considering it is supplied from a self cutting tap and it is more than enough to feed a decent jetwash. I will still upgrade the piping as the flow is reduced significantly when I use a long hosereel to get round the front of the house. I still need to change the stop tap and as modern stoptaps do not operate as a check valve anymore I cant see a problem with using a lever ball valve instead but am interested to know if folk think there is any merit to the notion of having a check valve on the incoming mains? The plumbing in my house has no tanks or way to contaminate the mains from backfeed (other than the outside tap connected to a hosereel but it will have its own checkvalve) so I am not concerned about it for my own situation, just wondering how much of an issue people think backfeeding is in reality. Some of the things I have read/heard in the past make it sound as potentially deadly as the great cholera epidemic but I have never heard of it actually causing any issues. On a similar note I would also be interested in what folks views are on deadlegs and legionnaires disease? Again I have never heard of any issues and there must be countless deadlegs out there but obviously if it did happen it would be very serious indeed. Please don`t take this post as the ramblings of a neurotic man, I`m just keen to learn good practice and not poison any customers. lol I am not a great follower of rules but I do respect the safety of others. (usually!)  |

I`m just keen to learn good practice and not poison any customers. If this is going to be used commercially, you'd better adhere to the regs. Isolation, drain off cock and double check valve inside the property. An integrated check valve in the tap isn't up to regs in a new install, although it's OK to replace like for like on an existing tap after failure. Rules are for fools, but that won't stop insurers from saying no to a payout if they find out, so for an extra few quid you should do it to regs. As far as dead legs and Legionnaires are concerned it's extremely rare to get an incident bad enough to harm anyone from something like dead legs, but it's possible, there have been cases in hospitals etc. that have caused deaths and made a lot of other people very poorly. It's often from stagnant water in air conditioning systems rather than from the taps, shower heads can be a risk though if not cleaned adequately or anything that sprays the water. You can drink legionella infected water and you'll be fine, it's when it's sprayed and you breathe the infected water vapour into your lungs that it becomes an issue. I remember the Basildon one from years ago, they knew a lot of the plumbing needed re-doing after a survey showed potential risk, they didn't bother, then decided to cut the budget for the water treatment that had been put in place. Shortly after that an old bloke died of Legionnaires. My mum's had dead legs in her house for 40 years from when an extension was done, none of us got Legionnaires. |
