I have installed an 1 1/4 Wet and dry line of the same size - approx. 1,500 feet long. It was hard to estimate how many taps this woods was gonna have. I believe there is a book/guide for how many taps you can have for this size setup. Is there anybody that share with me what that number might be? This is my first time using a wet/dry system. I'm hesitant to post how many taps this ended up being out of fear for being called an idiot but in fairness, I didn't guess the number of taps very well and find it hard to guess this. Thanks in advance!

Who do you deal with for supplies? You should be able to consult with your dealer on those numbers. The folks at Roth could help you. I’m not sure what the max number is on 1 1/4 but I’m sure some guys on here know.

Should be no reason for anybody to call you names, we are suppose to learn from one another. Iam currently running 1300 taps on a 1" wet dry system

There is a formula out there. I know Leader put up an estimated sizing chart in one of their catalogs a few years back. It did not come up in my search. We are putting up a 1 1/4 mainline with the potential to add a wet line to it in the future. I know we can use a 1" line in this particular location, but wanted the extra space in the event there was icing and the cost was not much more now.

It depends some on your slope and pump but 2% slope is 1080 taps with a 30cfm pump. 1.25” maxes at 11 cfm @ 1500’ with 30 cfm pumps or bigger. The 1.25” wet line is most definitely big enough. Given those numbers on a tight system in my opinion I wouldn’t shy away from 1500 taps. You can always put in boosters/manifolds or whips or run more lines later to help get the max cfm. I wish I could get 1000-1500 taps on one 1500’ run!

To clarify your question on the 1 1/4" wet/dry line, how many CFM does your vacuum pump produce? unc23win was correct with the vacuum numbers a 30 CFM pump for the 1 1/4" dry line at 1500', but the Cornell Vacuum book chart shows the maximum number of only 870 taps on a 1 1/4" dry line at 1500' with 30 CFM pump.

250 taps on 3/4"
500 on 1"
1000 on 1-1/4"
2000 on 1-1/2"

when you switch to wet/dry that can double but you don't want to put saddles on a wet/dry. if you have no choice put them on the top(dry) line.

I have a system with a 1 1/4 wet and a 11/2 dry and run 2500 taps on it with no problems.I have 18 main lines coming off that.9 main lines to the right and 9 to the left.Glenn Goodrich laid it out.

I had a system set up 20 years ago and at the time I ran 2 lines one to the north and one to the south. Both were about 1500 feet with 1 1/4 wet and dry. Had 4 mains coming off each. I started out with 2500 taps between the 2. Today I have 7000 about 3500 on each. Ideal. Not by todays standards but it works for me. I do run 150cfm pump on it. Need to tear 1 end out this year to log and will change some when I put it back in. Plan to do the other the next year as have lots of ash that will die and fall on it so plan to be pro active and cut them all and then put up new mains.

We use a 1-1/4" wet /dry setup but ours are underground. We feed our 1-1/4 wet lines with 1" above ground mainlines. Several of our setups extend well beyond 1500' in length.
We average between 1500 and 2200 taps per setup. We try to keep our slope at 2% but some lines have as little as .75% slope. Never had any issues. The key is proper sizing of vac and having a tight system.

Thanks for all of the input and examples of what is working for you - I will be at 2,100 taps - .75 -2% grade. It just turned out to be more taps then originally estimated and made me worried. We have support posts every ten feet so we should be good since everything is new and leaks shouldn't be bad at least for the first year.
