Slow drains or plumbing issue in new house?
Why does my tub shower drain so slowly that you get a pool of water around your feet but then after about 15-20 minutes suddenly empties out like nothing is wrong? Sinks doing same thing – it’s like someone suddenly opened the drain although it’s been open the whole time. Should I be worried about a more serious plumbing issue?
If it is a new house as you say then you have a serious problem. Either the plumber did not properly vent the drain system, or the sewer tie in is faulty, (not enough pitch in main sewer line).
Contact the builder to find out who plumbed the home.
It could be that the drain vents were never hooked up. You did say it was a new house. My sister had a new home built and kept noticing water getting under their home. They spent a lot of money building up the dirt around the house to only discover that the plumber never hooked up the drains after final inspections. I would suggest you call the plumber that did the work. We all make mistakes.
quite often during new construction rough-in plumbing is left uncapped at deck level where wood shavings etc. can get down the pipe. a new house should still have some warranty time left — if not — sounds like the time to call roto-router and have the branch line checked for debris. venting is either going to work or not and in the same way each time — clogs often act in strange ways as you describe.
**** SORRY FOR THE CAPS***
COULD BE A VENT PROBLEM NOT ENOUGH AIR FOR THE PIPES TO RUN SMOOTHLY
OR IT COULD BE A SMALL AMOUNT OF SOAP BUILD-UP.
TRY SOME LIKE LIQUID PLUMBER OR SOME OTHER TYPE OF PIPE DRAINER.
