My daughter's flat has a Fortic which is due for replacement. There is no gas, and the cold pressure is great. So, she has lousy HW flow from the Fortic, and loads of flow from the cold taps. The electric shower isn't exactly Niagara Falls either! Can you buy an unvented cylinder just for use...

The hot water pressure to my kitchen tap is rubbish. Its a monobloc, but supposed to be ok for low pressure. Flow to other hot taps is fine. Problem is my vented system is in a bungalow with a minimum pitch roof, so raising tank is a no-go. The flow/pressure to the cold in the kitchen tap...

My Honeywell 2 port (normally closed) V4043H is nackered and approx 20 years old. Not sure if its the head or the paddle. Lever a bit stiff and slow to return. Heating is coming on when it shouldn't. However, there is no way I can get a spanner on the valves 22mm nuts as there are other pipes...

Just bought a new kitchen monobloc mixer. It's got copper tails, they widen out at the end to 15mm. What's the technique for bending these. Presubably I must attach them before bending, otherwise wouldn't be able to turn them? Do I use external/internal spring? To what angle is it safe to...

I have a Concord WRS (Ieal) boiler, Potterton EP 3002 progranner on a gravity HW, pumped heating system. If I wanted to change it to pumped Y plan (I may also change boiler to a Broag), do I just have to change the flow pipework to fit a mid pos. valve, and add a Y plan pack (wiring centre...

The pictures below show the view of the gable end wall from inside my loft. Its a bungalow. At present, the soil stack vent enters the loft through the loft floor, crosses the loft in front of a breeze block wall where I want to mount a new boiler, and exits through the roof to the outside...

I need to replace my 8.5 kw electric shower, and am considering a 9.5 kw one instead. Will the existing 6 mm twin and earth cable be OK?

I need a new electric shower to replace my 8.5 kw one. The market seems to be split between Triton, Mira and Redring. The Redrings seem to offer good value, and have a 3 year guarantee. Do the pros who fit these for a living have any brand/model preferences in terms of performance and...

Having mastered (almost!) the art of soldering end-feed, the biggest problem is horizontal pipes that keep trickling water for ages. Obviously impossible to solder. Does the piece of bread in the pipe to stop the water long enough to solder trick really work? Are there situations where i...

When I try to solder small end feed elbows, connectors, etc I don't have too many problems. When I try to solder bigger fittings, especially 22mm tees it seems to go pear-shaped. :oops: Which of these two techniques is correct; 1) point the flame onto one branch of the tee until the...

I'm fitting a new bathroom chrome ladder towel rail. I'm using straight TRVs, so that the pipes go down to the skirting vertically. When I fit the TRV, is it best to have the TRV head under the rad, or sticking out to the side? Which way is best to make the trv work properly?

System = Open vented, microbore, Ideal Icos boiler, 5 rads) Can I use Sentinel X400 Sludge Remover or Fernox equivalent in my microbore system? If yes, how long do I need to leave it in the system with the heating on, before draining it out? Many thanks.

My son has a small 2 bed flat. The combi is shot, and we need something with small external dimensions to fit the small kitchen. The DHW output seems OK for him. Are these boilers recommended, or does something better fit the bill? Size (small) is important here!

The Glow worm combi was fitted before I moved into my house. Its in the loft. I need to move a rad pipe that will mean draining the system. Last time I looked in the loft, I couldn't find a filling loop anywhere. Do I refill with the small plastic detachable knob that adds water to the...

SYSTEM = Glow Worm 30 cxi combi & 6 rads. The TRVs in the house that we have recently moved in hiss loudly at various settings. We have resorted to turning all TRVs to max (which obviously defeats the object of having them), but some still hiss, especially when the heating has been on a...
