Guest guest Posted January 14, 2007 Share Posted January 14, 2007 Need ideas New Pool would like to hook up LOR for lights & pump to have a water show Starting to make plan with pool installer. Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 Watch the amps. My small pool from wally world, drew 3 amps. Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 Would it be easier to have the water fountain always running and just the lighting on them.... Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 I agree, last year, the fountain had a real bad time keeping up. It takes about 1-2 seconds to get the water pumped through. That may seem small but its accualy a pain when sequencing. Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 Also I just thought of all the stress being put on the motor. Is kinda like an inflatable with LOR. You should always keep the motor running just light the lights up for them to be noticed. Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 I just Did and on/ off . No more then 2 times during a song.the floods dont work unless they are underthe water, or in the back acing the viewers. Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 The way the real water shows do it is to have a pump going, and control the flow with valves. It's a lot more complicated than that but that's the basic idea...-Tim Link to comment Share on other sites More sharing options...
Guest guest Posted January 14, 2007 Share Posted January 14, 2007 I was thinking about a manifold an a couple of selonids, but even that would probbly harm the pump more because it holds the pressure in. Link to comment Share on other sites More sharing options...

This would allow water to keep flowing at all times.Brian Link to comment Share on other sites More sharing options...
Guest guest Posted January 15, 2007 Share Posted January 15, 2007 Controling a fountain with LOR is not that big of a deal. As has been pointed out you need to plan the sequnce 1-2 seconds in advance to the water effect inorder to allow the selinoid to open. I use a 1-1/2 hp pump feeding 1-1/4" flexible irrigation pipe to the fontain with 8 - 24 volt sprinkler valves. Attached is a picture showing one of the spray heads. The outter ring is divided into 4 quanterants with 7 1/4" Harbor Freight brass air chucks each. This seems to be about the limit that the 1" PVC and pump setup can handle and still acheive 15 feet of lift. Attached files Link to comment Share on other sites More sharing options...

Guest guest Posted January 15, 2007 Share Posted January 15, 2007 Its a cheep pump from walmart, the pool is about 5 seasons old. I used it lasyear with diffrent pond sprays.hopefully i can get a sprinkler valve form HD or menards. Link to comment Share on other sites More sharing options...

I believe the 'real' shows have some sort of auto pressure relief valve that keeps the water recirculating (sort of like power washers do). This is on the order of the suggestion above to have an 'extra' valve that piped out under the water, except that it's fully automatic.-Tim Link to comment Share on other sites More sharing options...
Guest guest Posted January 15, 2007 Share Posted January 15, 2007 Might be able to get away with using a simple pop-off valve like the ones used on water heaters. I have no idea what pressure fountain type systems operate at. Link to comment Share on other sites More sharing options...

Guest guest Posted January 15, 2007 Share Posted January 15, 2007 Yup, just mount your popoff valve under the water level and no one will even know it's there. Link to comment Share on other sites More sharing options...

One of the facts of liquids (like hydralic fluid) is that they do not compress. Link to comment Share on other sites More sharing options...
Guest guest Posted January 16, 2007 Share Posted January 16, 2007 You wouldn't be compressing it, just maintaining a reservoir. I'm not sure why it wouldn't work...that's how every well system in the midwest works. I have a pump/tank in my garage on a well for my sprinklers...it seems to work.

Guest guest Posted January 16, 2007 Share Posted January 16, 2007 Correct, water is not compressible. Holding tanks use an air bladder which is compressible to keep the pump from running continuously. Pump runs until it builds up to a predetermined pressure, say 50 psi, and then shuts off until the pressure drops to another predetermined pressure, say 30 psi. The advantage is that in a home/well system the pump does not kick in everytime the faucet is opened or the toilet is flushed.The major disadvantage to this system in a display would be that as the pressure drops the "fountain" would not maintain a constant height. As the pressure dropped the fountain would decrease in height until the pump kicked on again.I am guessing that the best way to handle a display system would be to have the pump always running and then have a valve to close the recirculation and open the fountain.
