Hello,
I am Carine, founder of www.madeinwater.co.uk
I have noticed that a few hits on my website came from this forum,
so I had a look and saw the tread on our hose.
To answer few questions:
When we started to look at suppliers to offer a filling hose as part
of our kit, we noticed that actually most Garden hose available in
DIY shop carry the following warning "not safe for drinking water".
We then, talked to few hose manufacturers to know more about hosing.
A lot of chemicals are used in the usual garden hose to make it
durable and flexible. Those chemicals have the bad habit to break
down and release toxin especially as the hose get older.
Can I use a Garden hose for my water birth?
Most company include a basic garden hose in their kit, and also no
research have been done on the subject I guess we can say that it is
probably safe to use it as no harm have been reported until now.
However it is strongly advised to use only a brand new garden hose
and flush it with fresh water for few minutes before filling the
pool (This should flush away 80% of the chemical residue).
Old garden hose, release even more chemical in the water as the
material break down and will carry on releasing toxin even after
being flushed
Why do we supply a non- toxic hose?
For ethical reason I will not supply my customers with something
that I will not consider to use myself.
It is the same as organic food. We all know that harmful pesticides
are spayed on fruits and vegetables, some people will choose the
organic fruit when other will carry one buying the standard fruits.
At Made in Water we are very pro-organic and pro-natural, and if
there is a safer option available then I think it is best to supply
people with.
When ordering as part of our kit we do not charge more than other
company that are offering a cheap garden hose.
Made from the food industry, our hose can be safely use and reused
as they are designed to deliver only fresh water and treated against
bacteria.
Hope this will answer some of your question
Except from being a "hose expert" I am also the mum of 4 little
ones, passionate about waterbirth and home birth so I'll be glad to
answer any other questions.
