PPS and my workshop ;)
Screwfix site is not getting the coverage that it`s used to (since the move) so had to look around for somthing better.
And on the subject of DeJa Vue, this site reminds me of the UK Workshop site with all those familiar names ;D

Some use a different name on here from UKW so might creep up on you Jim. �;) ;D

It seems that you can also direct rainwater into a soil drain now as this is what I did ( and he passed it).
Perhaps I just got a good inspector.

Is this kosha?

I've been thinking about putting a cover over the walkway between our back door and the garage door, but one of the things that has put me off has been that I knew I couldn't tap into the downpipe from the roof to handle the runoff, and was looking at having to dig a soakaway.

Have they changed the rools on this recently then?

Thing is we have a double drainage system, soil at the back and rainwater at the front, ground is solid clay which made a soakaway out of the question and it is impractical to run the rain water to the front of the house so it was the only and best option (thank god ;D)

from approved doc H

2.2 Some public sewers may carry foul water and rainwater in the same pipes. If the drainage system
is also to carry rainwater to such a sewer, the following provisions still apply but the pipe sizes may
need to be increased to carry the combined flows (see paragraph 2.35). In some circumstances,
separate drainage should still be provided (see Approved Document H5).

and

2.8 Combined and rainwater sewers are designed to surcharge (i.e. the water level in the manhole rises
above the top of the pipe) in heavy rainfall. Some foul sewers also receive rainwater and therefore
surcharge. For lowlying sites (where the ground level of the site or the level of a basement is below
the ground level at the point where the drainage connects to the public sewer) care should be taken to
ensure that the property is not at increased risk of flooding. In all such cases the sewerage undertaker
should be consulted to determine the extent and possible frequency of the likely surcharge.
2.9 For basements containing sanitary appliances, where the risk of flooding due to surcharge of the
sewer is considered by the sewerage undertaker to be high, the drainage from the basement should be
pumped (see paragraphs 2.36 to 2.39). Where the risk is considered to be low an anti-flooding valve
should be installed on the drainage from the basement.
2.10 For other low lying sites (i.e. not basements) where risk is considered low, sufficient protection
for the building may be possible by provision of a gully outside the building at least 75mm below the
floor level. This should be positioned so that any flooding from the gully will not damage any
buildings. In higher risk areas an anti-flooding valve should be provided, or the drainage system
pumped (see paragraph 2.36 to 2.39).
2.11 Anti-flooding valves should preferably be of the double valve type, and should be suitable for
foul water and have a manual closure device. They should comply with the requirements of prEN
13564. A single valve should not normally serve more than one building. A notice should be provided
inside the building to indicate that the system is drained through such a valve. This notice should also
indicate the location of any manual override, and include advice on necessary maintenance.

So the answer is yeah its kosher, if yer drains can handle it. In fact most houses here are combined rainwater+grey water. Not WCs though.

It seems that this rule varies both regionally and to individual inspectors. I posted on another forum stateing that top water was not allowed into the drainage system but many people stated that their inspector allowed them to do just that, so I guess its just pot luck.

quite possibly robbo, by-laws and the like probably come into force regarding this. My own house has combination 3�" rainwater and sink/bath/basin/shower water with seperate 4" foul(WC) stack

Having just built an extension on the back of my house that will be used as a kitchen/diner and is nearing completion I thought I would share some of the `ways round` or `stupid` (his words, not mine) regs that the building inspector (very nice chap he was too) imparted on me during construction.
First (and best of all), my plans specified a min 50mm cavity wall, as will all new builds from plans submitted prior to Jan 2004

He meant to state that the wall must have a minimum 50mm 'air space' which does not include insulation

We dug the foundations and called the inspector to pass them, he did so without much hassle apart from wanting to small pool of water removed from the bottom and we procceded to have a little chat (as you do) and I mentioned that it was a pain in the neck having to build two extentions, one inside the other (cavity) as prior to the new regs we just used to build in 8 and a half inch block work.
His reply was " well you can still build in solid block but you need to insulate inside with 35mm thermal plasterboard which is very expensive"

He meant to say that walls can indeed be block built but must achieve the Uvalue standard of =< 0.30 and this can be achieved with a combination of high density thermal blocks and insulation

I enquired about the price of the board and found that it would work out at approx �250 to board the inside with this board, a small price to pay for half the work load me thinks so that`s how it was done.

Drains no longer need to be leak tested as long as the components are made by a recognised maker.

[He has been drinking or smoking naughty nettles
ALL drains have to tested and only a fool will not thoroughly test all of the drains and manholes (err sorry thats should read inspection chambers). �Either water test or/and air testing

Electrics in new builds will become part of the building reg as from jan 2005 (a different reg controls electrics in change of use or established buildings) and if you havent got a `spark` to pass and give you a certificate

Again he meant to say that a revision in Part P of the bregs states that all new circuits in a domestic installation must be certified by an approved electrician from Jan 05

for your instalation then the council will charge you �100 to inspect it up to a max of two times (�200) Don`t know what happens if it fails twice.

You must have a cooker hood ducted to the outside in a new build kitchen.

Spot on

A utility room must have an extractor fitted to remove steam (?)

Yep - Thats another one

It seems that you can also direct rainwater into a soil drain now as this is what I did ( and he passed it).

....If you want to be fined upto �10k per connection except where no other 'reasonable' form of disposal can be effected as in soak away or other means

Perhaps I just got a good inspector.

Nope! He's a facking nutter.
