Hi, I'm planning to put a WC+sink vanity unit in bathroom, and the soil pipe needs to exit at the side. Can I use a pan connector with integral pipe boss horizontally (parallel with floor), or must they only be used so that the waste drops into the soil pipe from the top? If it's...

I've got 2 rails with 150W heaters to wire in. As I've got a spare channel on old central heating timer switch, I was going to power them through that in series. The timer switch is already being used for the hot water so is already on a fused spur. Is this in accordance with the current...

I've seen a few links to the calculator on this site, and I was wondering if I need to apply diversity before entering the circuit power? http://www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html

I'm moving a kitchen, and have an 8m waste run from dishwasher and sink to the soil stack, with a 90 deg bend and a dog leg round a chimmney stack. Should I be using 40mm, or 50mm with AAV?

I'm moving my kitchen from one side of the house to the other as part of an extension. The existing house has just one ring main off an RCD, and I'd like to add 3 more sockets for the new kitchen. It seems a bit excessive, but should these be on a new ring main, or can they be added to the...

Will the existing ring main be overloaded due to the new kitchen? It already has a kitchen on the ring, it's just going to be moved. The oven and hob will be on separate supplies. What's the best way to put the new circuits in? A bigger replacement CU, or adding another onto the existing...

I'm planning the wiring on a 2 storey extension. Current CU is full, with the following ccts: RCD(40A shower, 32A sockets), MCB(6A lights up,6A lights down,6A smoke, 32A cooker). Current loading on lighting circuits is 590W upstairs and 840W downstairs. The new lighting will give an extra...

It will be a brick extension. I was going to get a builder to do the shell, (walls, floor, roof, windows, maybe drains) and do the inside myself. As you say, I'll get quotes, and if they are low enough i might get some more help on the inside. Thanks for the figures.

Thanks for the replies. I'm a bit confused by the link, as it shows the double storey per sq m to be more than the single storey price. Then it goes on to contradict itself by saying single storey is more expensive!? Think I'll believe the text, as it agrees with your comments, and makes...

I've seen general estimates for extensions quoted per sq m. Is there a different per sq m price for single and double storey? Assuming the size in sq m is doubled for a two storey. I would expect it to be less for double, as the roof and foundation costs will be the same, apart from extra...

I must confess, i didn't check the pump. I'm not sure how. It's a Grundfos UPS 15-50. Is it just a matter of removing the four allen key bolts and having a look round? or just firing it up when it's dry, and checking for noise?

Regarding EliteHeat's reply, I can't get to the feed and vent as it's either somewhere in the floor or buried behind the new fireplace that's replaced the old back boiler. This is a concern for me as the feed and vent are at the opposite side of the house to the main boiler. i thought they...

Thanks for the replies. I can't think how you'd design the pipework to work with the pump only on the return, please could you tell me how it might be different? The water's still flowing in the same direction. The boiler manual definitely shows the pump sucking water from the top tapping...

I've moved into a house with a floor standing Glowworm hideaway 100b, approximately 20 yr old. The system is (was) a slighly unorthodox s-plan, with the pump on the return and the heating valve on the flow and hw valve on the return. It's an open vented system, with the feed and vent coming from...

ok. Thanks for the advice. Matt.
