Plumbing in the Home/Pipe diameter of outside frost-free hydrant


I need to replace the yard hydrant, which leaks all the time through the weep hole whenever the water is on.  Everything is so rusted, I cannot get it apart to fix or adjust. The present hydrant is a red Waterford 1" i.d. pipe, 1.25" o.d. 2' bury (for central OK). There is a 1" supply line from the well.  But a 3/4" fitting is at the bottom of the 1" pipe, and, of course, the garden hose fitting is less than 1" diameter.  Hydrants in 3/4" i.d. are easy to find (Home Depot, Amazon) but 1" are not (i.e., Y1-2 vs Y34-2).  What is the benefit of having a 1" i.d. pipe with a garden hose fitting at the end over having a 3/4" i.d. pipe?  Flow of water is restricted to smallest diameter.  What would happen if I installed a hydrant with 3/4" i.d. instead of 1" pipe?  Thanks!.


Yes, you would have less flow, but you should be aware of the fact that anything in the water well or plumbing department from big box stores is going to be far less quality than brand name products from normal suppliers who sell wholesale to installers.  I buy from Baker Monitor who makes yard hydrants and other water well related products.  Their products are the quality I would want if I was going to go the trouble to install one. You can see their products here:
If you find one you like, let me know and I'll get you a price.

I am a Water Well Driller and Water Pump technician. I own a business in Riverview, Fl. We repair motors and pumps in shop and in the field. We repair and replace submersible and jet pumps, galvanized and bladder tanks, and their controls. Water filtration is another one of our specialties.


I started drilling and repairing wells and pumps with my dad in 1958 at the age of 13 years. I worked with him on weekends and in the summer when not in school. After graduating high school, I worked for my Dad until going into the Army in 1968. I spent three years in the Army then went back into the Well Drilling/Repair field.

Many Forums including my own.

High school and a few courses after getting out of the Army. They were offered on the GI Bill.
