Question DetailsAsked on 9/3/2017

How do you bleed water lines to eliminate surges. I'm presuming air is in the lines...

My kitchen sink faucet surges with both hot and cold water. No other faucet in house does. City water.

Do you have the same question? Follow this Question

Remote kitchens (long run from main water lines) are a common problem for this, because the long run makes for a considerable mass of water moving along which comes to a screeching halt when you close the faucet.


Actually, air in the lines generally reduces water hammer - as long as you do not have actual slugs of air coming through and causing vibration. And you bleed lines by running water at all water demand points - which for the kitchen faucet would mean - running the faucet.


It could be the faucet design shuts off too fast - try operating the handle more slowly and see if that reduces the problem. Otherwise, you may need a surge or water hammer absorbing leg or device under the sink. There are commercial ones that easily can be put on the existing piping - the old school and actually generally more effective method (if you have headroom under the sink) is just extension legs on the piping (hot and cold both) sticking up from the shutoff valve as far as thereis clearance. This provides an air pocket which absorbs the water hammer (surge) similar to the way auto shock absorbers work.


Should take about $100-200 to install, depending on your local labor rates - almost all labor cost because the arrestors runs $15-30, and just putting pipe extensions on maybe $10-15 materials.


Plumbing is of course the Search the List category to get this work done.
