Best liner/ bedding for drop tray

[debbie26pet]

One of the nipples on my Glug has given up, so looked on the omlete shop and can find a replacement nipples, can anyone tell me if we can replace the nipples on Ethel and how or we're, tried ringing omlete but no one seems answer phones.

They look like they might unscrew, and be serviceable, but I have a drippy one, and am reluctant to try in case they are just moulded to look that way.

 

It's the only consistent source of water my chickens use, and I don't want to break it.... nor do I want to buy a new one either... if this is the only option, I would try and buy one that 'is' serviceable.
