you're right on both counts Fred
the domestic water is seperate and its ok to use immersion
the heating will catch no harm empty, just make sure the heating programmer/timer is switched off,

Just a point about the downstairs rads not draining. They are almost definately on a drop feed from 1st floor and as such will not drain back up over and down through your drain cock. Some systems are temperemental and do cause problems re filling, through air locks or blocked feed pipes. A common way to get round this is by bottom filling with a hose pipe via your drain cock, or anywhere you can tap into system. this usually forces the air up and out. Hope this helps.
Thanks. As per oaplumb's post i better do the 'work' of swapping the 3 port and the drain valve first. But then, to understand you correctly: fill up from the (new) drain off valve at the bottom to force the water (& air) up, yes? Just the drain off in reverse i think you mean. I guess you just need to do that until it reaches the f&e ? Sure that has an overflow pipe anyway just in case. Do I need to have any rad bleed valves open during the process? In thought you said you’d already done the 3 port |

In thought you said you’d already done the 3 port No, sorry if confused. No, I have it (a honeywell) to do (unlike the new drain off valve as yet) but when i said i need to knock the power off to wire it up there were several long faces in the fast flow house, so I've earmarked it for tomorrow now. Any booby traps awaiting me on the 3 port? (My plan is to take a pic of the x5 wiring to check i have the right connections going in to to board.) |

I think these plug and sockets should be a mandatory requirement, as once someone goes inside the wiring centre it's a right work over identifying which wires which due to typical very tight access space! |

If the problem is they old dreaded air lock in flowfastfred's system, I've had a few recently and shifted them by removing air vent or blanking plug(which ever is easiest)to work on,screew a valve tail into the now open air vent and put a hose onto rad tail and open the rad valves up and let the water flow for abit, you'll hear the water gurgling as it passed 👍🏼

Thanks PB. i agree, they look very good. I doubt i can get one now in time w/out ano time costly trip to town to get one or wait for one in the post. ( I am way behind now due to the shinanigans with the rad valve: turns out it is an old (mid. ninties -ish) Myson valve and so I bought a 1/2" / 15mm replacement with a decent drain off this time. But ... turns out the old one has an old imperial thread on the feed pipe, so the nut / olive wouldn't just screw into the new valve. Plus when i got it off, it seems that the pipe is actually 10mm anyway (the imperial nut is way bigger than a 10mm and much closer to a 15mm to the eye especially with a few coats of paint on the pipe ... so off i pop again to buy a 10mm... and then just the hour plus getting the olive off. Had to cut it off (carefully) in the end. Wowo the stress of that. So all done now - bar checking for leaks when it's all filled.) Back to the 3 port. Fortunately, my wiring centre is front and centre as you go in the airing cupboard, so if I take my time (& follow Tom's / Looch's tip below - thanks for posting Tom) I should be OK this time. Eveything's crossed. 😉 |

I aim to complete the fittings and fill trying OAPlumb's filling method first. In other words, I'm not au fait enough with a tail valve & the method you mention without a bit more of a janet and john explanation, sorry (my fault, not yours). |

(& to Looch obvs.) As above, mine if actually very accessible and even has daylight with the door open, so I should be OK without the x5 way connector thingy. If I'm not back in, say, 3 hours, you'll know it didn't go so well ! 😉 |

you're right on both counts Fred the domestic water is seperate and its ok to use immersionthe heating will catch no harm empty, just make sure the heating programmer/timer is switched off, It's all going off on this job btw Tom. Mrs Fastflow had a right old moan about no H/W, so I said, no worries, I'll whack the immersion on... Of course it didn't work & the 'hot' was stone plonk & I was the one in the (red) H/W. Ano flippin job thinks me - new immersion element or stat. But, when i went to move the towel mountain to get at the 3 port valve, i saw ano switch in the cupboard (as well as the one downstairs which i thought was the only one). We've literally never used it before to know / check. So, of i can't crack the 3 port / refill etc., we might still be able to get some H/W (however, haven't actually tested it yet). Fingers crossed. |

hello Fred, No don't try filling from the drain off, we might come to that if it gets desperate, ( I'm tom by the way) , what I mean is, if the tank upstairs is not going into the system, put a hose pipe on a drain off thats convieniant and works and drain the water from there and leave it running, then check the tank is filling and running in the system, This will suck the water from the tank, when its flowing good, shut the drain off and let the system fill up. Hi Tom, Well I'm not dead so far from the re-wiring (yet to fire up the boiler & test tbf) All the new iron is on & seems watertight (so far). Filled the f&e tank again ... & seems to have filled the system & stopped filling due to the ball cock. all inlet / outlet rad valves open ... but had all the bleeds closed in case the water decided to spurt out if those? So now: 1. do I use my (shiney, new and well designed - take note Myson) drain off valve at the lowest rad to attach a hose and run off some more water - so it's basically flowing / flushing through? 2. do i need the bleed valves open during this (see above - will they just piss it out over Mrs Fastflow's carpets though?) 3. Can i fire the boiler (heat & H/W) in the meantime, even though i haven't flushed it (as above) and it may still have the air lock(s)? (I doubt I'll have time for full on flush now, this afty.) Thanks. 😀 |
