<br />Pointless question. First, the last head in a zone is not a saddle tee connection. Second, you don't design a system where too much pressure difference exists between any of the heads on a zone. (5 psi would be a lot) Third, and most important, is if (as you indicate on another thread) you have only a 50 psi static supply pressure ('static' means with no flow) you won't be looking at anywhere near 50 psi at the heads. The saddle tees will still work at less pressure.

No not a pointless question maybe a misworded one. fact remains im not familiar with saddles and I want to be sure that i wont have problems.I have a total of 94 sprays and rotors and at 2 something a pop isnt not cheep either, verses installing tees. I just read in other threads that the higher the pressure the better the seal.I feel i have low pressure to start with. I guess it boils all down how low a pressure will the saddles seal without leaking. I do understand that I wont have 50 psi at the heads. At 30 psi will they seal properly. Finally this is my first system ive designed Im just trying to gather info before I put the shovel to the ground, so please easy on the unconstructive criticism no need to be rude.

just make sure you have a good seal.

<br />50 psi is fine for the saddle tees - they don't require line pressure to be sealed.

50 psi is good but what about at the last spray head whe nthe pressure is 50psi?

50 psi is fine for the saddle tees - they don't require line pressure to be sealed.

Is there a minimim psi that blazing saddle tees require to work effectively? I ve read the higher the psi the better they seal. My system starting pressure is 50 psi. My concern is down stream as the pressure drops if there will be leakage because of too low of a pressure to seal properly.
