Sorry the PRV isn't connected to anything. If its gonna go its gonna drip in the garage

Ah I meant the automatic air vent. The PRV has leaked before but stopped. The air vent is the one that is calcified.

The boiler is in the garage so as far as I know the only pipe outside is the flue. There is a brass pressure valve runs up to the top left like a whistle right. The fitting is loose and calcified but its dry. I will try the bag idea when I top up next. The boiler is quite happy running now with...

Thanks for the reply. Ive topped up the CH system and bled it a few times but still it looses pressure. I cant find any leaks so i think this expansion vessel is just the start of the problems. The boiler starts the CH at 6:30am with a gargle so i think something else must be wrong. If the...

Hi, Ive a potterton Puma 100 in a house that we have recently bought (4 bed detached). its on its last legs and loosing pressure. A plumber says he can change the expansion chamber that might solve the problem but its best to put the money towards replacing it. So after lots of searching...

No it's all copper. I've bled it all and the noise is much better apart from the one room where I think it's a pipe touching the joists or boards. I guess I'm back the the problem that air is getting in somewhere. I can't find any leaks at all.

Nope, some neighbours have had it done and the surveyor said ours is not done.

Hi, I've just moved into a new house. It's probably 12 years old and is sporting the original potterton puma 100. The house is a 4 bed detached and at the moment the heating is on most of the time and the house isn't that warm. I'm having cavity wall insulation done next week which might help...

Fair points!

Actually, I'm assuming this old thing has no function to alert a telephone number so when I get some time I'm going to build a telephone system for the house. Maybe I can take a feed from the electrical circuit such as the signal wire to the bell box to tell the phone system the alarms been...

Thanks for your help mate. I will have a think about the garage. I've one spare zone but I might daisy chain it of a toilet window contact close to the garage. My main worry with alarms is annoying the neighbours by not being able to silence them. I will order a new battery tomorrow for...

Got it! The instructions I had we're to remove the jumper and use the wrong pin on PA. it's all reset and programmed. I want to add the garage but I'm not sure how to get the cable to it. There is a window contact closeby that I could chain it to I guess. The psu is buzzing on it which is...

Despite being sensitive i think this specific engineers code is easily guessed. :D . Ive got all that info but i can only find an engineers manual for an accenta 6. I was hoping once ive reset my optima that most of the programming was the same. I will try again but the instructions i had...

i didnt want to post completely what i did as some people are sensitive about putting such information on a public forum. Basically ive follwed the NV Ram reset procedure to factory reset the unit.

Thanks for the reply. So i understand you correctly, the internal sounder is ringing on power up (regardless of the reset wire) because the battery is dead? the saving grace i have whilst messing round with it is that to silence everything i can knock the fuse out.

Sorry i forgot to add. Im not a buglar, i just prefer to carry out the work myself. I would like to program it how i want and ad another PIR to the garage. Im a competent technical person so i dont see why i sould put money in other peoples pockets without having a bash first

Hi, I've just moved into a house that was bought from one of those ‘we buy any house’ companies. They have no details from the previous owner of the alarm manual or code. I've done a good searching on the internet and found user manuals and engineer instructions to reset it. An...

Sounds like I need to be replacing it. I am brassic at the moment so a call out and repair might be the only option.

Cheers. Also the automatic air vent seems gunked up with calcified water deposit stuff. It's not wet but it looks to have had a constant leaking of water somewhere. Tbh most people I spoke to on the estate said they have replaced the potterton boilers. I suspect it's 15 years old

Do you have any idea an what the cause of it could be? The noises are mostly upstairs in one area. I've bled the radiators a few times but it seems more air is just coming back. I can't understand how it could loose that much pressure without any signs of water
