I have tried removing the white plastic thing. Removing it does not allow condensate to flow. No changes have been made to any boiler settings. Not on the house thermostat and not on the boiler itself.

I installed it myself. That said it has worked flawlessly apart from a periodic & sudden depressurisation problem that no engineer has been able to identify the cause of. This de-pressurisation happens may be once a month and started a number of years after the boiler was installed. It was...

We have a Grant Vortex 36Kw combi keroscene burning boiler, which has two expansion vessels fitted to the heating side of the boiler. Recently we added a bit of pressure to one of the expansion vessels. Since then the boiler has stopped producing the by-product water that's produced when you...

Thanks Bernard, I get that entireley. Thank for your wise comments. However I'd still like to know as much about this as I can. Why? Because as I pick up the phone to the electric network company they are going to ask me to describe what the kit is and what I want done. Last time I had a similar...

House service fuse box outside flat. Fuse box shown has live wire from street coming in and then out the top, as shown, for flat and neighbour. Flat supply exits on right of photo as shown. One fuse for each of flat and neighbour. Writing on box seems to be "ISCO Henley Series 3" if my bad...

I am replacing kinked iron cable. Crimps joining power lead inside iron look like this. Anyone suggest where to get these or alternative?

Need to do a job where there is no mains power. Anyone any experience with this sort of thing for prolonged use with car engine switched on...

Thanks. I've got those and another set too. A ring saw would be ideal but they are too expensive. Likewise a diamond chain saw.

Thanks for that. We tried building up the bit size from smaller to larger hole. This does not work at all when hammer drilling into granite. What happens is the larger bit edges get stuck in the hole. Probarly part of the reason the clutch failed. On the Ebauer drill when the bit caught the...

Drill bit I am using is Irwin Speedhammer Plus 14.0 mm x 210 mm. I am going the full 210 mm in. I have tried lots of different drill bit brands on granite and the Irwin speedhammer plus is the best I have found. £5.18 each plus delivery...

Because after drilling 30 or so holes in granite with 14 mm carbite tipped drill bit specially designed for granite, the clutch in this drill failed. Must have become overly worn after the bit got stuck a few times...

Looking for a hammer drill for a lot of granite drilling. Needs to have 3J impact energy, or there abouts, and be completely servicable. One I'm using has drilled 30 holes and the clutch has failed. Recommendations?

I can make the holes in the steel and the granite fr attaching the bolts no probs. I've heard about epoxy systems etc for gluing bolts that hold structural steel onto stone. Anyone got an outline of the various methods for attaching steel to stone using bolts.

There are holes. What would you do with them

Have a garage. Corrugated steel external wall is rotting. Need to clad it with weather proof cladding that won't rot. Here been to GAP plastics. They recommend 2.4 m x 1.2 m, 3 mm thick white uPVC sheeting. This would certainly keep the weather off and preserve the steel corrugation, but would...

63A or 6A trips when lighting circuit switch is activated. Photo of breakers attached.

New BG domestic box has been fitted. Everything in box works ok, without tripping, except the led lighting circuit, which trips RCD every time wall switch is activated. Lighting circuit trips either B6 RCD it is connected to, or larger in line 63A RCD. LED lighting circuit works Ok when MCB...

Thanks John, it's your 'private' category. The meter is for indicative purposes so we can assess the cost of running plant. Have you a technical view of this? thanks

Building has a 3 phase supply in from street. A room in the building draws from one of the phases of this 3 phase supply. Room needs to be seperately metered. My understanding of what spark wants to do is he wants to tee off one of phases into meter then to seperate fuse/RCD box for the room...

Want to put meter between three phase box and new metered supply. Spark saying just use one of phases to new box with meter between. Is this correct?
