@terryplumb pics of the valves are attached One end has standard TRV The other end doesn't have a traditional lockshield. It like another TRV. Family are reporting that as the pipework is coming out of the wall horizontally and there is no play/movement in the pipe, getting it off the wall is...

Many thanks Terry. Okay, I will get family on the case today 1. Go to each valve (flow/return) on the ground floor rads. 2. Open then up with pressure topped up 3. The valve which doesn't release water /heavy stream is blocked/restricted I have a standard hose. To connect the hose to the...

I will start off with this option. What should we do? Test? Etc to establish/ clear any possible blockage?

1. Last week the boiler wouldn't fire up/run. It had an F75 error. 2. Vailliant engineer changed the pump and the boiler began running again. The system was installed about 2 years ago. I know that it had inhibitor.. Can't say whether it had a chemical flush. But it definitely never had a...

Contacted Vailliant: They won't send an engineer. They said that they'd be surprised if this is a pump issue as it was just replaced. According to Valiant, the ground floor rads not working suggests an airlock/ restriction. Would a power flush sort out the issue? I was thinking of getting...

Woah.. Never thought I'd see the day. The legendary poster who's always helping others actually has a question :mrgreen:

The ground floor rads were not checked. Today I have - bled all rads - drained the system - stuck wet vac on end of a ground floor rads to remove any possible airlock - I've shut the valves upper floors and opened the ground floor and still no heat. The pipe (i suspect it is the flow)...

I have a system boiler for central heating and unvented cylinder tank for hot water. The heating is controlled by the Nest thermostat. The pressure is 1.2 Not sure how to adjust programmer for hot water/ central heating Hot water comes via the unvented cylinder. We have gad no problems with...

No zonal heating Only one thermostat

All ground floor rads are not heating up. On the first floor, two (of four) rads get hot and two are giving low heat. All Rads in loft area are piping hot What is the problem? Background: 1. Boiler is Vailliant 637 2. After switching it on for 1st time, following summer, it had an F75. So...

Want to paint my skirting black with dulux trade high gloss (oil based). Currently, the skirting is painted white with Johnstone Aqua (water based) paint For a proper, long lasting job, can I 1. Rub down the skirting with 240 grit. 2. Use Zinsser Cover Stain (oil based primer) 3. Finish...

It's oil based satin wood in black. Water based on stairs? Really? Is that a good idea? The whole reason I went for oil based in the first place is due to its durability/toughness Can water based paint take heavy use from everyday staircase use? Good point. To be fair, the only parts that...

Two years ago, I painted my wooden stair case (pine and ply) with Zinsser Bin & Dulux Trade Satinwood (oil based). Overall the paint job is still in great condition. However, high wear areas e.g. tread nosing and newel post are looking tatty and are in need of touching up. Can any of the...

Apparently, the gas was capped by the council as the property was unused for a long time. So who do i call to get the boiler commissioned? Building Control?

There is plenty of credit on the meter. Thanks. I spoke to the supplier and set up a fresh account when i moved in. As i have no idea who installed it, i will call out a gas engineer to commission it. They will hopefully be able to get everything up and running and provide Warrent for the boiler

You're like Agatha Christie putting all the right pieces together to crack the case. :mrgreen: Yes, the supply was switched (prior to me moving in) by the gas company to pay up front (prepayment) mode. What's the significance of switching from credit to prepayment? The boiler is new but...

You 'can' or 'can't' tell if capped? If you can't tell, would a better pic help out? Or do i have to get a gas engineer out?

New boiler is refusing to ignite Looking at the gas meter and i am wondering whether it has been capped/sealed? Could someone confirm from the pic?

Thank you. Learning everyday.

That's brilliant. Thanks for confirming. I am glad that the regs have taken a common sense approach. Extra low voltage isn't dangerous/ fatal, so they should give you more freedom to bury the cable outside of the electrical safety zone. The above is just my opinions.
