My scenario is that the outside stop tap has had tarmac laid over it by some bright spark in the past and the internal stop tap has seized and is leaking. The kithcjen fitters need the water off to take the sink out and the water company cannot even come and look at the outside stop tap till end of next week. We thought we would try out one of these freezing kits!! there is 22mm plastic rising main thats then joins a 22 to 15mm reducer with copper 15mm coming off to a seized stop tap. We used a freezing kit and froze the plastic 22mm pipe aprox 8 inchs away from the stop tap as that is the furthest we could possibly freeze it due to the floor level, Everything went great it froze ok took old stop tap off just literally about to tighten new stop tap up when the plug give way and then the tsunami come!! absolute hell, tried to get the new stop valve on with it gushing out and there had got to be around 6 bar coming out of this rising main upto our ankles in no time and soaked trying everything. I managed to get a pushfit stop end on the pipe which has stopped the flow but now we have no water untill next week when the water board come out. I cant understand why the plug just gave way because the instructions reckon you can sweat a joint on just 6 inchs away from the plug without it melting? Im gonna have to have another go at this but ill be honest im **** scared really knocks your confidence. I called a few plumbers and once i told them what i needed doing that just didnt want to know lol. What I need to do is refreeze the pipe remove the push fit and fit new valve if it goes to plan not even 30 mins work but just worried that its going to be difficult to remove the push fit due to the pressure in the pipe even when its frozen, thats if it freezes but will not know untill ive moved the pushfit but then it will be to late . If i do get the pushfit off is it going to disturb the plug again?
