I wouldn't trust anything cheap. I've lost dozens of rats because of leaky nozzles. I have tried both kinds of nozzles from Reptile Basics, but I really prefer the vari-flow valves, these: http://www.reptilebasics.com/vari-flow-drinking-valve I do not like the rodent valves, these: http://www.reptilebasics.com/rodent-...rinking-valve/ I've had nothing but trouble with them. I contacted Rich and he was great, sent me new parts which fixed the problem, but as soon as they get dirty again they leak. You have to take them apart fairly often to clean them, and I'm just too lazy for that. The Vari-Flow valves don't have that problem. I've had maybe one of those leak in the 4 years I've been using them.
That's a really good idea!
