Thanks Porque We've also had a site visit this afternoon and it looks like we have the following: 1. 40-50mm water supply reduced (inside the building at point of entry on the ground floor) to a 22mm pipe. I'm guessing we can remove the reducer and run a larger pipe from here. 2. Gas...

Hi Everyone Thank you all again for your advice. Agile you're right...we'd totally overlooked this and in all honesty (and in our ignorance) didn't think it would be such a big and complicated thing. We thought 7 showers to be reasonably little especially for a gym. We've spoken to a...

Hi Simon Thanks for your reply. We get the keys next week so we will need someone to come and check the water supply. Not sure if its possible to say but is there a standard or reasonable fee for this? On the gas side, there is no gas supply. I've been reading up on Hamworthy...

Hi Agile Thanks a lot for your reply! The showers are for a gymnasium to be located on the first floor of commercial premises in London. While not all the showers are likely to be used at the same time all the time it might be the case at certain times of the day, especially in the...

Hi Everyone! We need some advice on powering 7-8 showers. We have no idea what's a better option - multiple instant water heaters, storage heaters, unvented heaters,etc. In an ideal world what we would like (in order of importance) is: 1. Efficiency (in both purchase/install costs...

Hi guys thanks for your advice. DCdec, I will pm opps to see what he reckons, etc. Thanks again! Z

Hi DCdec Thanks for your reply. I will be getting a few quotes in to see if we can get a pro in...that said, at the moment my times cheap! :) Just to be sure, is it 400l for 7000 sq metres or for 7000 sq feet? Same with the time...as size wise it's a big difference...we have total a...

Thanks Pigeon Will look into it...on the plus side it saves us a fair bit on equipment, requires less skill/experience and probably less masking around windows etc! Is the painting time as fast or is it the total time ie prep work of spraying, cleaning guns, etc. that makes using a roller...

Hi All We are taking a lease on 7000sq ft premises. They're a shop storeroom type of space - solid concrete walls, ceiling, etc. We want to paint it all in white (walls and ceiling) without plastering for the most part (straight onto the cement walls). The walls have been painted in the...

Hi All We have an old house (about 200 yrs old) with a thick old wall that's suffering from damp. Its an external wall and on the inside there is damp along part of the wall on the ground floor. We had a valuer/surveyor look at the problem (can't find specialist damp company in the area)...

Hi everyone! I am wanting to install a ventilation system in a gym changing room with 12 showers (6male/6female). Firstly, is this something that can be DIYed? I have pretty wide DIY experience and have rewired domestic premises, fitted bathrooms, kitchens, built cabinets, tables, etc. but...

I'd thought that the domestic CU would let me have dedicated lines (each treadmill would have its own MCB) closer to the treadmills rather than running a wire/dedicated line all the way to the main DB (which is quite far from where the treadmills will go). In an existing gym I look at today...

Hi Simon I'd thought to surface mount all the electrics in metal conduit/trunking with the plugs on the conduit itself (some will be on the floor behind the treadmills making it easy to plug them in). Initially I'd thought to have 3 domestic-type consumer units (1 off eAch phase) and have...

Hi and thanks (yet again)! :D 1. For the treadmills we are budgeting 10-12 for opening and hope to increase this up to 20 if the demand/money is there (it wouldn't go above 25 in any event because of a lack of space). I want to have the wiring done for all of them though (20-25) so that...

Thanks again for your help! Just heard back from one supplier: 1. current rating - need a 10A dedicated supply 2. Startup current - approx 8A depending on weight of user 3. Typical running current - approx 3-4A Does that sound about right or should I ask them to confirm anything else...

Hi Xr4x4 and Simon H2 Tbh I'm not sure, that's simply what the supplier have told me. I will ask tomorrow and see what they say. So far they've just told me that each treadmill needs a 16A dedicated line (I know that other suppliers say the same thing for their treadmills too). I do hope...

Hi and thanks again for all your advice. If I need more power, would that need a separate 3 phase supply or can more power be "sent" through the existing 3 way power supply ie increase A to more than 100A? (I'm guessing no, but thought I'd ask!). Def need to get onto electrician too...and...

Hi and thanks for your replies. Using the 36 way board as an example, does that mean that 20 treadmills would use up 20 single phases leaving 16 for other things like lights, etc. Also, can't I have 1 single phase going to a 240v CU which then has 4 treadmills on dedicated supplies each...
