ror, I guess I thought the mainline was 700 lf and the dripper section was after that. Miscommunication happens when there is only written words without pictures or being there in person to see the site. Oh well sorry about that. The BFP makes no sense if the run to the drippers is short. The PR also restricts flow. If the drip lines are 700 LF long that is very long for drip lines. Usually the lines are broken up into several segments with solid lateral lines feeding the segments. Each dripper is saps pressure but with a drop of 50 feet in 700 the slope is 7% slope which is quite steep. You might look into placing the drip lines along contour lines of 1.5% or 1.5 feet per 100 feet slope with solid laterals between the contour lines. This creates an even flow from all drippers and will keep the water within the tube lines longer. This also equalizes the pressure to all laterals. If you know your flow rate and pressure before going into the drip and you know the flow rate and pressure loss for the drip line or at each emitter, you can calculate if you have enough flow and pressure to make it to the end of the lines.

Hi - a lot of these posts seem to be slightly different but thought I would share my experience in my home that may prove helpful or be similar. My wife and I moved to our home newly built 5 years ago tomorrow! I can't say I've noticed the smell in the first year but maybe it's poor memory. After the first year, we'd notice this propane/rotten/dead animal like smell. At first I thought the builder put something in the vents - no signs of any rodents ever and ruled this out. Next I checked the line/drain from the AC/furnace and even had a tech check and clean the pump - no help. plumber says there is no issue with drainage or sewer or any back up venting - ok. what HAS helped intermittently is calling the gas company to check the gas lines inside. I've had them 7 times in the past 2 years, each time they find a small leak - nothing major, no reading except with the sniffer right at the source of the leak. {I also have multiple CO and gas detectors on the floor (heavy gas). They have never gone off}. After the gas company repairs the pipe the smell is gone for a few weeks maybe months depending on warm or cold season. It comes back, gas company is back out and repeat. I have replaced two ovens in the kitchen due to them being the source of the leak. I find that the air return on the main level of my house sucks in the smell and returns it to the furnace. When the furnace kicks on we smell it out of the vents. Occasionally I can smell it in the room where the furnace is also. Gas company has done line checks, pressure checks, fixed leaks - I've paid them thousands to come out and fix this over and over then the smell returns - I've returned two "new" ovens due to leaks after minimal use. I have a 2 yr old son and new baby due in a month and NEED this resolved. Please let me know if you have any suggestions or have been through something similar.

tech was just here...ready for this? cold water inlet pipe was leaking on the electrical control box for the pump. he replaced the box and replaced a fitting in the pipe...fired right up. he also asked how much oil i had delivered this morning...told him 150. looked at my tanks and the gauge...he said it's likely that i had oil to begin with and the moisture getting into the box and causing electrical problems is the likely culprit.
