The only problem with some concrete posts is that they can taper slightly towards the top meaning that any post bolted to them could lean slightly - you can overcome this in a couple of ways. 1. cut/plane the post to the same profile as the concrete post and bolt up. 2. Pack out the gap...

I installed my own CH and plumbing using Hep20 over 8 years ago without any problems. I have a combi boiler which makes the overall pipework layout much simpler than a system using tanks etc. I must admit I was a bit sceptical of plastic pipe and push fit joints but after talking to a builder...

Are the posts the original boundary markers or actual fence posts that have a slot for a fence panel? Do they have holes through - they may have rusty wire blocking up the holes! How tall are the concrete posts? Are they regularly spaced and firmly fixed? If they are short with holes for wires...

Could it be . . . 1. Due to increase in number of combi boilers in use, a cold feed is prefered as, for example, if the boiler needs to supply hot water to the washing machine it starves the CH or other taps. 2. It is cheaper to have one valve instead of two. 3. Water is heated up to desired...

When did the problem start? ie was it after the new thermostat was fitted or after rads bled etc? Did you repressurise system to manufacturers recommended settings after bleeding - through filling loop. Have you tried adjusting thermostat settings? Is thermostat in the correct position? - not...

Do not confuse the pressure of the pressure vessel - mine can be checked with a tyre valve - and the pressure of the central heating circuit measured on the boilers gauge. You could recheck the pressure in the pressure vessel to confirm it is correct - if not it would point to the fact that it...

I think adaptors are available to connect the two materials but from your description you sound like you will need a new branch in the main stack to connect the new toilet into. In this case it may be easier to replace the whole stack etc in plastic as working with the cast iron can be a bit...

Hi, I have a Saunier Duval SD623 combi. In the bathroom I have a telephone style shower mixer (non thermostatic). I am currently just getting enough hot water for a decent shower (8" rose) without needing any cold adding. If I put a thermostatic mixer valve into the system will it affect the...

Hi, has anyone seen or actually used the bath refinishing kits that are available, such as "Tubby". My bath could do with doing but I would like to know if the kits are any good before I start sanding down the enamel. Thanks

The door frame is usually put in first so the plasterer has something to plaster up to. If you are using a high quality timber frame that you don't want to get covered in plaster ie varnishing instead of painting, you could put in a lining of something like mdf and then fix the frame into this...

Have a look outside where the overflow/vent pipe is. You may find it is letting water out there. Mine did this due to a dodgy pressure vessel.

I think it is recommended to lay the new floor at 90 degrees to the old one - you could also lay an intermediate layer of foam or whatever the flooring company suggest to even out small imperfections. Be careful of laying a floor over boards that may need to come up for access to...

Even though I piped my system in plastic - the same theory should be OK with copper. I ran the bulk of the pipes in 22mm and branched off from manifolds in 10mm to the rads. As Brezer says 10mm can look neater than 15mm as it is quite easy to run the pipes down behind the skirting instead of up...

I am not an expert on combis - but from my own experience . . . Is the pressure when cold correct - my boiler for example has a pressure of around 1.5 bar when cold which increases when it gets hot. If the pressure should get to high through a malfunction or whatever it should vent through the...

You could drill into the grout/cement and use a rawlplug and screw to secure the wood or what about using "No More Nails" or similar to glue it down - obviously clean the area thoroughly and check the pack for suitability. What exactly are you trying to secure?

Apologies for stating the obvious, but if the pipe up to the valve is very hot but only warm after it and you have bled the rad etc, then it sounds as if the valve is not opening properly. Have you tried it at different settings? What is the ambient temperature of the room - ie is the room warm...

Couldn't you buy some from the hire shop? If not I would phone around local builders merchants.

The floors I sanded with the belt sander were fine - although it is quite hard work as the sander wants to drag you around the floor! I swept and vacuumed up the dust from the floor as well as the walls before finally wiping with white spirit to pick up all remaining dust. I lightly sanded...

I have used a similar idea to fix my fences. The short posts I used were concrete with holes for attaching a wooden post. I used lengths of threaded rod with a nut and washer at each end (cheaper than long bolts). Dig a hole and concrete the spur post in a similar way to concreting in a normal...

It sounds like the thermostatic valve is sticking. This is basically a valve with a temperature senitive wax "switch" I imagine these can wear with time - not sure of the usual life span though. Have you tried opening and closing the valve several times - it may free it off. If all the other...
