I've got a Vaillant Turbomax Plus 837e. Lately it's had a few instances where it just doesn't deliver hot water. Possibly happens once a week, I press the 'reset' button, the boiler restarts and all is well. However, this morning it's worse. A reset doesn't help. If I turn the mains power off...

I'm running Blue 25mm MDPE pipe at a depth of around 750mm to feed a new outside tap (which will eventually form part of a pop-up sprinkler install). I believe I should come up above ground with some sort of rigid pipe for the tap. What is the best pipe for the job here, please? Copper or...

My Daughter has moved into a flat that has no provision for a Washing Machine. There is space for one, but fitting it would need some trickery with the drain hose. I could fit a new proper waste pipe underneath the units, but it's a lot of work considering it's not my flat. I'd not hesitate if...

So, we're soon to have our Bungalow rendered, but I don't know how to approach the below-DPC section, that won't be rendered. Initially, we had thought of painting them, but is the condition too bad for this to be successful? What you're seeing in the pics is after I've cleaned them the best I...

We've got a renderer booked in for the end of this month to finally cover up the nasty brickwork of our 1920's bungalow, using K-Rend. However, as with most, they won't render below the damp-course. They've recommended 'blackjack', which I guess is a bitumen paint. However, the brickwork isn't...

I have a Double Pantile roof and would like a recommendation on a decent solution to exit a bathroom extractor through the tiles. Could anyone help?

I have a Vaillant Turbomax 837e Boiler. It has been cycling fairly strongly on the Hot Water side. I've recently replaced the DHW Heat Exchanger which appeared at first to have fixed it, but actually it hasn't. It has improved a lot, but it's still happening. Previously it would go from maximum...

Morning all. I have a 1930 3-Bedroom Bungalow, built from Norfolk Reds. The brickwork is extremely scruffy, it has had alterations over the years where non-matched bricks were used and there are various other faults that are simply too much to do anything else with. As much as I hate to say it...

I have a couple of questions regarding Cavity Wall Insulation. We had Cavity Wall Insulation installed a few years back, I think they used Rockwool (it's a white, wooly material). The Bungalow has a number of Air Bricks at low level, presumably venting the sub-floor. When they did this work...

I'm in the process of building a new front Doorstep. I'm planning to build formwork, before pouring a Concrete foundation, then laying stone Treads and Risers onto a Mortar bed. There is an existing structurally sound cast-in-situ Concrete step in place that has been there for almost 100 years...

I need to move an existing outside tap by about 6 feet. It looks like its piped in lead right up to the tap. I've dug right down and found the t-piece where it branches off the main supply pipe. I just need to cut it off on the branch and extend it to the new location. Is this best done in...

So, my Vaillant Turbomax Plus 837e displays the signs of having a blocked DHW Heat Exchanger (hot water temp cycling hot/cold). I've removed it, expecting to see a gunked up mess, but frankly it wasn't as expected. I've run water through it in all directions, seems to flow and it's currently...

Our Bungalow was built in the 1920's, we've renovated it and have lived there for 10 years. The front door has always been a bit of a pain, but I've only really just taken the time to think about why. It's actually positioned a whole brick course above the damp course. Is this normal? I'm...

Following on from something that was raised in another post, I'd greatly appreciate a bit of guidance. I have a fairly hefty Combi Boiler. I also have 4kw of Solar PV, which I feel I should be utilising to heat hot water during the day. Could it be viable to install a Hot Water...

My Boiler is around 10 years old, it's a Vaillant Turbomax Pro 837e, it's not a condensing Boiler. It was bought with a focus on DHW performance and, regrettably, no real consideration was made towards running costs. Today, 10 years later, I'm seeing monthly gas bills of £120-130/month over...

I have an awkward Radiator Valve scenario. I have a large radiator that I planned to be piped from the wall and to use 'Corner Valves'. Once I fitted the radiator, which was a fresh install, it was clear that if it ever had to be removed, due to the style of the brackets, it would be...

I'm currently arguing with my local DNO about moving of my Electric Meter. They initially said they could run my supply cable from the pole, to a bracket on the gable end and then into the loft via a 20mm access hole. From here, the cable would enter their regulation 32mm Smooth Duct where it...

The renovation of my bungalow has been going on for several years and along the way I've re-piped the entire Central Heating system. For right or wrong, the main circuit is 22mm, with the branches in 15mm. Every inch is insulated. I understand this is likely to be overkill. Now I'm nearing...

I consider myself to be a fairly competant DIY'er, knowing my limits. I turn out work to a good standard, but aren't shy about calling in the professionals if a job is beyond my scope or legality. I've bought 4 'designer' radiators from a UK company, who deal both on a trade basis and to...
