    What is a really good brand for pressure reducing valves?

    Thanks copea! My nearest CP is a little far but not too bad. The important thing though is knowing there are multiple places to get the parts. 1.5"... Dan it probably took so long to arrive cause they were making one for you!

    What is a really good brand for pressure reducing valves?

    Yes its so easy to do! If I hadn't spent ages trying to figure out if it came with the threaded tails as well I probably would have missed it too and ordered it, luckily I saw it before. (Also odd is that the product code they use isn't on the spec sheet that Honeywell provide.) Thanks for...

    What is a really good brand for pressure reducing valves?

    Thanks Dan! But that is a D04F, which isn't drop-tight, and so will allow the pressure to creep in no-flow conditions (and the hozelock connectors to pop off eventually!!) I am leaning towards Reliance Water Controls at the moment as they sell a PRV with all the working bits in a single...

    What is a really good brand for pressure reducing valves?

    Hi, I need to fit a drop-tight pressure reducing valve to supply a garden tap and associated accessories, as the house has very high water pressure. I do not want to worry about this PRV - I want The Best quality valve so once its installed I don't have to worry about it leaking after 12 months...

    What is the span of a pane if the pane is not rectangluar?

    Hi Ossy, Its supported at two edges; the glass does behave somewhat more plastically than I would have thought (the limiting factor in my span is the deflection! ;)) I will do a search of the standard but I agree; I posted just as a quick check and the lack of an absolute answer is the...

    What is the span of a pane if the pane is not rectangluar?

    Hi theoldun, Yes I am :D, or more specifically, I have determined that 6mm thick glass can span 1.1m with my loading. This is OK for almost all of the panels, but a couple that adjoin the gable exceed this at the top. I just wanted to check if there was a standard way to calculate the...

    What is the span of a pane if the pane is not rectangluar?

    Hi, Given a maximum span for a pane of glass calculated from BS5516, I am wondering what happens when the pane is not rectangluar (e.g. it adjoins a gable) and the longest edge is larger than the max span? For example, Say you calculated the span to be 1m (two edge supported) and the...

    Strength Grades

    Hi freddymercurystwin, I've seen that one and it is useful. But i'm wondering how they determine the span lengths. I take the lengths are based on a constant weight applied to the centre of the length, the max at which that grade at that CSA can safely take? But as seen from the tables...

    Strength Grades

    Hi, Ive been trying to read about timber strength grading, I have found a number of tables and recommendations talking about the grades and cross sections required for things like decking and floor spans, but I wondered if someone could explain what strength grading means practically in more...

    Anyone ever had a false positive testing for dead with...

    :mrgreen: Oh dear, I hope they didn't leave a forwarding address! Now that you mention it I am having trouble remembering. I know that in the junction box I removed them from there was a load of CPCs all twisted together but these may have been from the rubber sheathed cables; I do remember...

    Softwood outdoors

    Hi, The large outdoor project is a glasshouse, approx. 2x2x4m. I have a stone base (already built I am taking over the project) and I intent to complete it by building a timber frame. The stone base is high so the wood should never touch the ground. JohnD, I also remember in a previous...

    Softwood outdoors

    Hi, Thanks for your replies! Looking at Red Western Cedar it seems especially cost effective when compared to the cost of a length of hardwood. Why this preconception about softwood being unsuitable? Is it just because people consistently use poorer quality timber?

    Anyone ever had a false positive testing for dead with...

    Don't I know it! Unfortunately this is my parents house and they will not consider a rewire. Its not the money, its because its a beautiful old Victorian house that they've kept perfectly in character; original features and antique fixtures in fittings in every room, everything custom built...

    Anyone ever had a false positive testing for dead with...

    My multimeter was my test instrument (my nice one aswell!) I remember that unfortunately whoever installed it didnt (it was long ago judging by the cable to be fair to them :D); well, at least it isn't in a ceiling void anymore. ;) Not that that helps a great deal when the cable from the...

    Softwood outdoors

    Hi, Looking around it seems that softwood, as might be expected, doesn't fare well outdoors for long periods, however I can still find examples of it being used. Is it possible to treat softwood so it is resilient enough to be used for large outdoor projects? What kind of lifespan does...

    Anyone ever had a false positive testing for dead with...

    ...the back of your hand? Refurbishing basement today and removing the ceiling; being an old house there is alot of wiring that is disconnected and can be safely removed, so one of my tasks was to pick apart the installation and find out which of the 50 year old cables I could take out...

    Glasshouse design (timer sizes check)

    So would 69x69 softwood be satisfactory, with a wide margin for the roof, or should I be looking to use 96x96 at least to be safe? Thanks!

    Glasshouse design (timer sizes check)

    Sorry, with regards to the timber. I looked at hardwood as I thought it would be more resilient outdoors but while im not penny pinching with this project if you think properly treated softwood would be just as suitable I would rather go with that.

    Glasshouse design (timer sizes check)

    Hi, Thanks for your replies! The use of the two different sizes of vertical supports is for astethic reasons (supports vs. window frames). The vertical timbers on the bay needed to be wider due to the angle of the cut of the horizontals - resulting in a surface 'longer' then the width of...
