Fixed!

OK, I went back to the pump/irrigation store where I bought the valve. Fortunately, the owner was there to help troubleshoot this valve not closing. He said to go back and pull off the 1/4 inch plastic control line that runs from the pump to the hydraulic valve. Also, remove the brass elbow on the pump for the control line and see if they are restricted with deposits. Sure enough the brass elbow was practically closed up and the threaded opening in the pump was just about closed up as well with ...

System Filter and Control Valve Issues

I was actually thinking of a motorized valve, but at $500 I think I'll check with the shop where I bought the Toro valve first. I could always re-thread the stripped screws in the bonnet of the original valve and reinstall it too. I'll play with this one for a little bit & let you know the outcome. Thanks

OK, New Problem now...

Installed the new Toro hydraulic valve and I thought all was well. The small diameter plastic hose goes into a nipple on the bonnet of the new valve that has a very small orifice. Now, the valve doesn't close - so well pressure causes water to run out of sprinkler heads constantly. My understanding of the hydraulic valve is: once the pump shuts down, well pressure (thru the small diameter plastic line) is applied to the top of the bonnet diaphragm - since the diaphragm has more surface area on t...

System Filter and Control Valve Issues

I played around on tinypic.com for awhile and lost my patience! Yesterday I replaced the hydraulic valve and now the system is in great shape. The only problem I found with the original hydraulic valve was that 4 of the bonnet screws were stripped causing the leak. I was surprised that the diaphragm was in great shape as was the internal spring. After 20 years of service, I put it to rest and replaced it with a Toro valve. Thanks Again

Job Complete - A Big Thank You for your Guidance and Help!

A big thanks to Wet_Boots for help in bringing this issue to resolution. I picked up a compression fitting with a stainless steel grip ring and went to town on stopping the flow of well water. I was done in 30 minutes, didn't get too wet and the system can be properly serviced from now on. Next, I will tackle the leaking hydraulic valve (water sprays out between the bonnet and base). This will be a whole lot easier now that I can valve off the flow! Thanks again for your help and suggestions! Tr...

System Filter and Control Valve Issues

Obviously, I have to get a valve in this system (well side) in order to service the filter and service the pump should it ever fail. Does the Rain or Shine, or Wet R Dry adhesives work well with flowing water? It looks like the previous owner had some work done where the blue adhesive was used - why they didn't put a valve in at that time is beyond me! If the "Blue Glue" isn't going to work, I guess I can search for an 1-1/2 inch ball valve with compression fittings (either on 1 end or both). Th...

System Filter and Control Valve Issues

Well, I finally got around to removing the filter housing yesterday. Let's just say it was a very wet event! I placed a towel over the filter housing while unscrewing it so I wouldn't get soaked. The plan was to unscrew the housing, remove the filter and reinstall the housing if water continued to flow. Man, did water continue to flow - with so much force that I couldn't get the housing threaded back on! I ran inside the garage and turned the sprinkler pump on hoping to relieve some pressure - i...

System Filter and Control Valve Issues

Piping flow is: well supply to filter, filter to pump suction, pump discharge to hydraulic valve, hydraulic valve to indexing valve. Small plastic sensing line comes from pump to the top of the hydraulic valve. Hopefully, I will get to this this weekend!

System Filter and Control Valve Issues

Unfortunately, an emergency repair at my mother-in-law's house took precedent over my sprinkler system repair last weekend. Now a roof leak has quickly jumped up the priority list for me - I will post results as soon as I handle the roof problem. Home ownership just keeps you busy! Sorry for the delay.

System Filter and Control Valve Issues

I thought that as well. I guess the well pressure is keeping the hydraulic valve closed through the small diameter plastic tube on top of the diaphragm. When the pump is running, the discharge pressure is greater than the sensing tube pressure allowing the hydraulic valve to open. I can always take the filter housing off, remove the filter and screw the housing back in place while I clean the filter. I will have to wear my rain gear - don't want to stink like sulfur water all day! Thanks for you...

System Filter and Control Valve Issues

The pump was shut down for over a day before I tried to remove the filter housing. As I said, I unscrewed the filter housing a few turns and water was squirting out around the threads pretty good. I put a rag over the squirting water, unscrewed the housing a little more and left it for 30 minutes. When I returned the water was still squirting out with the same amount of force. I am probably just being a little chicken with this filter removal. The hydraulic valve is leaking at the bonnet seal an...

System Filter and Control Valve Issues

Yeah, I should have mentioned that the pump is inside the house to keep it out of the elements. The black plastic line comes from the pump to the top of the flow control valve. Timer/controller is inside the house as well to protect them from the elements. Is it normal to have pressure on the suction side of pump where the filter is mounted? Thanks, Corker

A few Pictures of the system

Well, it looks like it didn't accept the link from Photobucket. I'll try again May have to copy and paste link into your browser. http://s111.photobucket.com/user/BCork/media/Sprinkler/IMG_5268.jpg.html I hope this works from PhotoBucket. Thanks, Corker

System Filter and Control Valve Issues

Just bought a house in Central FL with an existing irrigation system (~20yrs old). I noticed low system pressure and I checked out everything I can see. Pump runs fine, water leaks from around the flow control valve top to body seam and filter looks all full of algae. Here is the issue: I went to unscrew the filter housing (which is on the pump suction side - well side) and there seemed to be a lot of pressure on the system. I put a rag over the threaded section and let it drain for 30 min - the...
