Hi, Guy installed full system to my bungalow last week, combi and 10 rads. nice tidy job, 22mm flow and return running around the loft, teeing off down walls to rads in 10mm pipe (chased in). all done in barrier pipe. Been up there today and can't see any bleed/air vents anywhere - going to...

distance from mixer to location for oversite is about 6 feet! how many bags of ballast and cement would I need to mix 1.8 cubed? or is it more economical to buy sand and gravel individually, rather than ballast?

thanks for the advice folks, i really wanted to do away with having 100mm of oversite as the foundation crete was pumped in at considerable cost, due to tricky site access. to have mr.concrete return with pump for a poxy 1.8m cubed of oversite would make me cry! will speak nicely to the bco...

i have the opportunity to choose either of the above systems for a small 1 room ground floor extension (18 sqm) - was all set to go with timber, but the bricklayer is trying to sell me beam and block. He says one of the advantages is that no oversite concrete will be required with b&b, just a...

..the builder tells me 100mm cavity is now standard. However, I've seen some plans lodged with my local authority that specifiy 85mm cavity. Meanwhile last time I extended 75mm cavity was used! The inner skin will be aircrete type lightweight blockwork, does the combination of inner skin...

many thanks for the tips! for some reason the skip hire contact estimated 6 cubic metres of clay soil will equate to 20 tonnes in weight, meaning 3 eight yard skips would be required. however, judging from responses this is a bit excessive, and use of mechanical devices to compact the...

this is where i excavate the trench and dump the spoil in a heap on, say, my driveway and the grab lorry comes along to scoop it away? is this more cost effective than skips for getting spoil offsite? Been qouted 100+ vat per 8yd skip.

I have a trench to dig for extension foundations, have called two skiphire outfits and received conflicting advice re muckaway: One firm stated 3 8yd skips necessary, the other between 8 and 10 8yd skips! Where they differed mostly was in how much the waste would weigh and how much it...

drain cctv was ok, water meter reading not budged for 2 weeks while away over xmas period. rules out 2 possible causes of damp! i have been made aware (by a local tree surgeon) that the neighbourhood has a high water table, which peaks in february. There are known to be underground springs...

yes this is the worst case scenario, which tbh i am prepared for. will research costs re getting a floor core sample analysed. assuming the floors are replaced, how are the internal walls treated? is a chemical compound injected into the base of internal walls once the slab and infill...

"You can CCTV the drains, and test the incoming mains" i'll kick off with these two items on monday. hopefully will be able to cross them off the list of possible causes. "If the floors are not significantly uneven then they can be left alone " two floors have a slight dip in the...

Situation: detached bungalow built 1958, concrete floors, hall and lounge floor covering is original wood block parquet, remaining rooms 'marley' type tiles. property has been uninhabited for several months. noticed there are no airbricks anywhere in the structure. cavity wall...

Thanks for the advice - it was an issue with power not being delivered to the bell box, as suggested. I now have another problem with this bellbox.... When the master control unit is opened the bellbox sounds. When I key the PIN into the control panel and reset, the tamper light...

:lol: u got it! Ok, been up the ladder AGAIN... Followed the installation manual exactly - opened control unit, so tamper circuit open - up to bellbox, swap jumper to switch battery ON - the left hand most LED is flashing.... Fixed bellbox cover in place, back to control box, closed it...

LED's not flashing. I installed the bellbox on Friday (without the yellow wire linked), and in the evening sure I saw the right handmost LED flash briefly. Maybe I was hallucinating!

Hi - thanks for responding with advice, the control unit is C&K 700, about 10 yrs old. I've been up the ladder this morning and wired as suggested, but can't get the sounder or strobe to activate. The internal sounder is working as expected, both when I select the 'bell test' option and...

Popping my intruder alarm cherry today... Replacing a dead bellbox which has a rotting battery and rusty pcb inside, with a texecom odyssey 1. There is 6 core cable exiting the control box, the odyssey has only 5 terminals... The source of each core in the cable at control box is as...

Many thanks for the advice - sulphate has not been proven, a structural engineer reported it is the 'likely' cause. TBH, the floors are in a bad way, as i described previously, and I want to make them good, both for my own use and so as to be able to sell the property on without issue in the...

...it appears many thousands of british home owners have wearily trodden the path I am about to take, due to poor construction methods in the 50's and 60's... I'm planning to dig out and replace all floors (they are awful, some sunken, some bulging, some cracked) - but I can't establish...

thanks both for responding - will consider honywell next time. I ordered and received what was described as a 'replacement actuator head' for this model of valve. Only the grey plastic box containing a motor and visible cog has been supplied - have i ordered the wrong part? I expected to...
