Old hose: harmful compounds?
My hosepipe -- presumably reinforced pvc -- has been around for a long
time, and I've just noticed that when I use it to fill a watering-can the first couple of gallons are very frothy. At first I thought it was traces of the washing-up liquid I sometimes use a drop of as a wetting agent, but it's definitely the hose itself. Question for the scientists: I assume I'm seeing products of the breakdown of the material, so are they likely to be harmful to plants, life, the planet, and everything? Mike. |

I have noticed this with new hoses as well. I suspect that it is just the first rush of water mixing with the air in the pipe to give you naturally carbonated spring water. Seems to happen more in the hot weather, so it could even be air disolved in mains water bubbling out as it goes through a hot hose. Run a glass full of cold tap water and leave it to warm, and you often see bubbles form on the inside of the glass - presumably gasses coming out of solution as the water warms. Cheers Dave R |

No, I don't think it's that: I get my water from a private bore-hole, and it does have a lot of dissolved gas. This is different: a real dense froth, which didn't happen when the hosepipe was new.

Mike. I think it might be the plasticiser from the PVC leaching into water in the hose. It's certainly much worse in this hot weather. Does your water smell bad ? - mine does. I spray a patch of lawn or something unimportant until the water runs cool and clear. However harmless the froth might be, I don't want it on my peppers or tomatoes. Mike |

Certainly the first thing I thought of was the plasticiser dropping out. I do the same with my first pipeful. Mike. |
