also, it'll be about an 8m run

After 3m you need to double the pipe diameter. 50mm minimum standard here.

awesome.

When agreed as so, my dear Watson......

afternoon. the wife is shopping for shower heads and found a drenching head that says it offers two flow rates with 17l/m standard and a 9l/m eco mode. what's the thinking behind this? is it to satisfy building regulations?

from the looks of it it's also a permanent solution rather than a switch between the 2 modes!

Building reg G2 stipulates a reasonable provision to limit wholesome water use to 125l pp/day. But there's also the argument that flow regulation saves water so good for the wallet and good for the environment.

Ok so with our toilets and washing machine using harvested water I can easily argue that even with the higher flow rate head we’ll be below that threshold. 

[saveasteading]

So 2 minutes at 17 litres is 34 litres or 1/3  of a day's recommended amount.

A good shower head should use far less water to good effect.

Therefore I would say to try the lower setting first.

 

Water costs about 3p / litre I think, allowing for supply and disposal.

Get kids and misses to piss in bucket and empty once a day - super water efficient. You still trying to save 25 quid ?

But it doesn’t look like it’s changeable so once bought it is what it is, and at £350 that’s an expensive mistake!

The cost of water is a good point and I’ll need to calculate our water costs per litre.

It isn't generally realised that the sewage charge is usually based on mains water used,  and about doubles the cost.

Harvested water goes free!

If you can send your rainwater to soakaway then you should be able to get a discount .

Yeah, no sewage here. STP all the way. I’ll just check the water bill for the existing property

Look elsewhere? Plenty of options on the market. We have one where there is a pack of regulators from 16l/min down to 6l so you can test and select the best option. Mine runs absolutely fine on 6l/min and it's a drench head, but only about 200mm diameter head.

thanks. it's hard to know what a 9l/min shower head is like as i've not had one before! the wife is doing the research on the bathrooms as i've got my hands full researching a load of other subjects.

I think you are out, should be 0.3p 

Mine is the most expensive in the land and was 0.53p/litre last year I think.

We checked our water bill and we pay 0.17p/l, so approximately 29p for a 10 minute shower at 17l/min or 15p at 9l/min.

Just checked mine.

Water was £1.9219

Waste was £3.1317 X 0.95 so £2.9751

So £4.9m³

Then add the daily charge of £0.1497.

I used 12 m³ over 93 days.

So 129lt/day.

With my government rebate of £50 a year, and the Water Share credit  of £13.

Plus the £30 Stop the Drop of £30, my last bill was £33.63.

So £0.0028/litre.

 

Really not that bad when I look at it.

Does seem perverse that to save water, SW Water makes it cheaper. But at least central government are coughing up a bit to help.

 

Off to have a deep soak in the bath now.

You better put a timer on that shower - you know ; to save money

I do my best thinking in the shower so I'll probably end up saving money by solving problems whilst showering.

 

it's man maths, init.

Just watching basically good, hot water, go down the plughole is enough for me to limit the time.

• Select button for spray options

Prob best to ask them by email, if this is pattern & flow rate, or just pattern at a set flow rate.

You can make a fast shower go slow, it's called "not turning the knob all of the way to max" .

Pretty simple stuff, eh

Yup. Those electrical items won't just pay for themselves!!

 

Just pull the trigger and have a nice shower, you tight arse, as you can't take it with you.

You are right. Wierdly that came into my head in the shower this morning.

Note to self :If a number is surprising, check it.

It's good. My Mrs doesn't normally have it turned all the way up .

[Pocster]

@Thorfun - I will genuinely have 1 of these spare soon if you are interested

Try telling teenage boys that. They only know how to turn it all the way and don't realise you can actually have it at another setting 🙄
