Check the flow from the valve. Make sure the flow control knob is not closed or turned down. Check again for a leak by running the zone for a extended amount of time and listen carefully.

SOURCE: low pressure valve in Audi A4 1996

Does it have a cycling low pressure switch in the low side line? If so remove it and charge through that port. Audi makes a tool for charging the AC.

SOURCE: valve pressure renault laguna

you must make sure the senser is the correct one.each wheel senser has to be correct.they are not the same.i think they are colour coded.say rear wheel wont work on front etc.sometimes inflate pressure to around 45psi on side that is faulty then let pressure down to correct level resetts the senser.otherwise think its renault dealer to reset computer

First recharging throug the high side is extremely dangerous and is discouraged by most HVAC mechanics.
High side pressure should read approx. 5x the low side. Low side pressure should read in the 40-45psi range unless otherwise specified by the manufacturer. Guess here is the system is overcharged is you're getting 70psi on the low side. Overcharging will damage the compressor and will underperform. Below is a link to a great source of information on AC.

Have a system 7 heads 5 feeding off trunk line two off of two tee lines. the system is feed by 3/4 pipe,it worked fine for 1 year know it won't always pop the heads.


Either the pressure has gone down due to a leak or the heads have gotten dirty inside and need to be cleaned out so they again pop out fully.

My sprinkler head is stuck spaying in one spot and I can't figure out how to adjust the range and distance of it.


Sounds like you have a bucket impact sprinkler. These are problematic as they tend to beat themselves into non-operation from the moving parts involved and the impacts. They stop turning for a number of reasons, low water pressure, dirt and debris filling the bucket impeding rotation, plants covering the sprinkler etc. If no debris is found and others continue to work on same zone the water pressure is probably unchanged it may just be tired. I suggest replacing it using a pop-up rotor preferably a Hunter PGP-ADJ or PGJ-ADJ Rotor as rotors have only 1 moving part a gear which is sealed inside the sprinkler making them very dependable.

Not enough flow and pressure to run sprinkler system


pressure in centrifugal pumps depends on the number of impellers in the pump housing, the clearance of the impellers to the housing and the power of the motor to drive the impeller/s
volume flow is also important as a pump without a high output will not produce pressure
check the jet size at the foot valve that is used to help lift water to the pump
It is a jet pump and will have a smaller line back to the foot valve for that purpose
next wil jet pumps if there is too much flow to the outlet , the pressure required to help lift the water to the pump is reduced and the volume is also reduced
you indicate 4 sprinkler heads per zone but how many zones are operating at one time
check the expected delivered volume for the new pump against delivered volume of the old pump as a starter to find the reason for the poor performance of the new pump
check also the rpms of each pump as that also has a bearing on volume produced

Not putting out enough pressure or flow to pop up sprinkler heads


Have you fixed this problem?
Q? Did you replace an existing pump. And what was the model and did it work.
Q? If its the same size as the fp4032, has anything else changed? Is there a filter that needs checking.
hydraulically to work it out I need the distance from pump to water, height and size of pipe. Distance you are pumping too, height and size of pipe. And what the "four heads are"? Nozzle size etc. To work out a flow/pressure rate.

I have one zone in my sprinkler system that has low pressure. I have changed the control valve and its the same. No signs of broken lines.


If it is a anti-siphon valve remove the anti-siphon cap and let it rip. Remove cap on adjacent valve and let it rip check to be sure the gieser is identical. If so let it run for a long time the leak will eventually show up. Because if it worked before and doesn't work now it has a leak. Water takes the path of least resistance. I have had them access the landscape drain before and you the leak didn't appear until it emptied at the street or followed a gopher hole a few hundred feet before surfacing. Listen carefully you will probably hear it.

If water just dribbles over the anti-siphon portion with cap removed it is still not opening flow control know may be turned down. In fact I would check to ensure this isn't the entire problem turn ir counter clockwise until it stops. This is the round know in the center of the valve.

I have low water pressure on my rainbird sprinkler system. how can i adjust it?


There are several ways to adjust water pressure on sprinkler systems. First you have to determine if there is a problem with the sprinkler system itself. Things to look for:
1.) make sure that all valves including the main are all the way open.
2.) Inspect the sprinkler heads for clogging. Sediment and debris can also clog your sprinkler heads. Some debris removal may be required.
3.) You make have too many sprinklers operating by one valve. You may need to divide a zone and add another valve to increase water pressure.
4.) If all else fails. You can install a breather intake cap to allow air into your sprinkler system thus increasing GPM (gallon per minute)flow.
5.) one of the biggest mistakes that peopel make is that they undersize the water pipe size to save money. Typically you want to use 3/4" PVC pipe for your main runs and tee into 1/2" PVC for your sprinkler heads.
Good luck. I hope this helps.

Sprinkler head does not spray water


Make sure when you pull the head to ck the screen you turn the system on and blow out the line, then run a hose through the head to make sure it isn't plugged up anyway. Depending on the head and the cost of a new one will dictate cleaning or replacement.

Brass Champion Sprinkler Valve


The lowest sprinkler head usually leaks until all the water is out of the system. The valve that controls the sprinkler system has a vaccum breaker valve on it. When there is no pressure from the water main the vaccum valve opens allowing the sprinklers to leak water so the house water won't get contaminated from the grass and dirt in your yard.
