We have been installing 22mm thick granite tiles on a screeded floor with UFH (which is running at about 15deg). These tiles are very absorbent but we have not sealed them yet. As the picture shows, there are dark wet patches on them. The adhesive is white so I do not see that there is anything...

That is why I said economical but that will do the job. I do not want to go over the top with a very expensive adhesive. The UFH has been running at an average room temp of 13 deg. I am looking for adhesive names for insytance

thought so, thanks

Can people recommend what are the most economical materials -that will do the job- and method to lay granite tiles on a house ground floor (dining, kitchen, etc)? The substrate is a sand/cement screed with underfloor heating water pipes in it. It is dusty but level. The screed was laid a few...

I have a wash basin, made from porcelain, which has a hole for the taps I bought that is small. I need to enlarge it, either the whole diamater or locally where the pipes go through, by about 6mm. Is there a tool that will do this?

I forgot to add something that may answer the question: these tiles are going on a screed with piped/wet Underfloor heating. Is it necessary to use flexible adhesive? because my adhesive is not.

Errr 7-9 months

I have some interior floor adhesive for use on cement screeds with granite and ceramic tiles but the date of expiry has been passed. The adhesive has been kept packed, covered, off the floor and in cool and dry conditions. Is it possible to test if it is still usable and whether it will...

I guess the worst thing that can happen is, if I start having problems with flow, get the water company to come and put a 25mm pipe from the meter, but will have to dig again....

I laid a 25mm MDPE pipe to feed my house and the water comany told us that we could make the connection to a pipe from the meter ourselves. However this pipe is an old style (probably imperial) plastic type that had been installed several years ago. This pipe is only about 22mm OD and 14mm ID...

That pipe must have been at the ignition point temperature of the PU foam, 100deg? 150? ;-) Yes, I remember now there is the fire resistant foam, better to use this one. Thanks for the feed-back

What material is allowed to use in the gap where a flue pipe goes through a brick and block wall? the hole is overzised so mortar is not likely to do it and I want to fill all the gap properly. The flue is from an oil condensing boiler with a twin wall so the outer pipe is just the one that lets...

Talking about that, does anyone know if trees can be damaged by the acidic plume? in which case you would have to go taller than any of the neighbour's trees that may be in the vicinity :lol: Talking to others, someone told me that he is in a (legal) dispute with a neighbour because the...

How high would the plume have to flow over the neighbour's garden so that he does not have a legal argument against my flue, 3m? 5m? 20m?

Do you know of any plume diversion kits that can be used with the Grant oil flue products?

Since other posters have lost interest in this thread, I am putting more information as a result of my converstations with others. I checked with the manufacturer's technical support and they agree to the recessed flue as on my drawing on the first posting. They just said to leave a gap of...

I read this document CE29, interesting. The distance of 2.5m is not mentioned anywhere in the Building regs. English Building regulations apply to the whole of England (unless there are local exceptions, I believe). So this distance of 2.5m is a recommendation to avoid nuisance. That is...

The conclusion of this is that I am buying the high level flue so that it exhausts over the fence. Otherwise I could get one of the guys above when I hire a plumber to commission the system

About the nuisance to the neighbours, that is why I am trying to avoid putting the flue over the fence where it is more likely that the discharge will be directed to the neighbour's property!

In that case it looks like the Oftec regulation contradicts BS and Building regs because the distance of 600m is specific to oil burning appliances. 2.5m sound like it would be difficult to meet in most cases. Are you sure this does not refer to other types of burners (some kind of old fashioned...
