Yup there are adders. They do hibernate.
Do my 50ltr at end of day before I shut garage door . I bought a 150ltr from someone on here a while ago first thing I done was drain it , two washing up bowls full of oil and water and rust , no wonder I could not get the dam thing working ..
Good job he didn't think it was a hissing snake
Problem with that is that I don't always know when "after use" is! I leave it charged thinking I'll go back to it and end up getting distracted doing something else
chuck it on a bonfire or drain water off up the garden and the rest in a wheely binJust out of interest, what did you do with that oil, water and rust?
Auto drain valve off ebay
Have one on mine. Don't know why I didn't get one sooner. Just set open time and duration and just forget about it.
The cheapo water traps off eBay come with an auto drain valve that pops open when the pressure drops to a low psi. I'd have thought this type would be much simpler to plumb in than a fancy electric one...
The ones I was talking about pop at a good few psi. I haven't checked but it takes more than a minute to drain off and would be more than adequate to push the water out. No good if your receiver doesn't leak down overnight but I thought it may be a simpler option for the hobbiest. Tbh though, I didn't realise the electric ones are so cheap.
