best value water tanks??
"bassett" wrote in message ... This is true. You must make sure your plumbing is good, especially polypipe joints are not as reliable as metal. As well as wasting water and soaking somewhere you don't want soaked a leak or tap left on may burn out the pump motor if it runs dry. My garden tank is turned off at the valve and the motor switched off when not in use for this reason. David What a load of paranoid rubbish, how do you think it works for people with only a tank water supply and a pressure pump. The same way it does for for my 45 kl house system which is on all the time. But the plumbing there is high pressure polymer or copper and has been pressure tested and it is protected by the house structure. I know people who have had exactly the problem that I described with garden and stock systems, this is not something that I imagined. I don't know of a case where the motor burnt out personally but my plumber advised me that it can happen. And a modern pressure pump is worth something like $120 , or there free when you buy some tanks. They don't need to be big or expensive. For the garden no they don't need to be big or high pressure and my 10kl system isn't. But the cheapos don't give mains pressure. I didn't say the previous poster needed a big pump I did say a little one doesn't give mains pressure. So tell us , how long have you had a tank water supply. Since I built the house. Your playing games with a **** arsed little tank and a garden hose. Why go to the gym when you can get all your exercise jumping to conclusions? Why the intemperate language? You do seem to have rather an emotional investment in your limited experience. You have no bloody idea. All my solar water fittings are poly type and I,ve never had a problem. with water pressure blow outs. Good for you but I don't think that proves very much in this context. Have you had a horse decide to play with your plastic fittings? They have big teeth that can disconect a waterer that is not well shielded. I doubt the previous poster will have this problem, I am just pointing out there are risks outside a domestic system. Perhaps carelessly driving a stake through a buried pipe is a more likely example. Poly fittings are simply not as reliable as metal or the crimped sort on high pressure tube, especially the push fit types (as opposed to nut and olive) that are mainly used on 12, 19 and 25 mm poly pipe which are common sizes for garden use. Some push joiners will blow out just on a low pressure pump without outside interference unless they are also clamped. Add together the lower reliabilty of the (most common) fittings and that there are other hazards found out doors and there is a real risk of pumping a tank dry due to a leak. David |
