  1. Installing utility sink for washer to drain to

    Plumbing
    Turning a standpipe into utility sink drain? Greetings!! I just bought a house and have discovered there is some build up in the pipes. When I run the dishwasher the standpipe in the garage backs up because the flow is restricted. We're being very careful about not putting anything that might...

    Plumbing
    We will need a drain extension tube when the new pedestal sink is installed. We are using a Metal drain and all metal 1 1/4 Chrome Plated Brass 17 gauge P-trap.

  3. New vanity, first time DIY. HELP!

    Plumbing
    Hello. I recently installed a new vanity in my guest bath. Seemed like it was going to be so simple. Unfortunately, I've been trying to connect the drain to the wall. The p trap and piping (outside of the sink drain) is 1.5" and would connect into the wall without issues. The issue is the...
  4. P-trap under bathroom sink not lining up

    Plumbing
    I got new countertops and my P-trap is not lining up. What solutions can I do to fix this? I have read to stay away from flexible P-traps, but this is the only solution I see right now, unless I can find a 45* bend that is only threaded on one side (the pipe at the very wall exit is threaded)...
  5. Shallow P trap

    Plumbing
    I'm constructing a tiny home this year on a trailer. I am doing my best to avoid breaking into the floor/ joists with plumbing. I have purchased a saniflo rear discharge toilet for example to avoid the normal (large) bottom discharge. I would like to find a shallow P-trap for the tub. I know...
  6. Help! Moving Shower Drain.

    Plumbing
    I am moving my shower drain about 1 1/2' to accommodate the installation of a new custom shower. My question is, due to obstructions I am unable to put the p-trap for the drain directly under the drain. I am trying to see if it is acceptable to place the p-trap about 3' horizontally from the...
  7. Bath tub p-trap

    Plumbing
    Replacing a sunken tub (bottom is below slab height) with a free standing tub on a new platform. The existing p-trap is in the slab. We will extend the drain plumbing higher to reach the new tub, but will use the existing in-slab p-trap. Is there an issue with the height of the new tub in...
  8. Connecting utility sink to washer standpipe

    Plumbing
    I think this is a pretty simple one - but I would like to get some feedback to put me at ease. Years ago I poured a basement floor. In that floor I placed a 3" standpipe with a trap. Currently the washer empties directly into the top of the open standpipe. So far, so good. I intend on...

  10. Min length for tailpiece?

    Plumbing
    Does the tailpiece for a kitchen sink need to be a minimum length before it enters the p-trap? Can it be as short as 3" without causing any problems? I would like to install the drain and p-trap as high as possible to open up the area underneath the kitchen sink. Thanks for taking your time...

    I am trying to install a 60" bathtub in the basement. The outside walls are of concrete masonry. The width of the room is 72", by that leaving 12" from the edge of the tub to the masonry wall. The 1 1/2" sewer line is at the edge of the masonry wall and runs horizontal into a backflow preventor...
  12. Worn out sink drain

    Plumbing
    I have an ancient sink drain that finally disintegrated. The P-trap and drain extension literally fell apart to the touch. The problem is 1) it's all copper pipe 2) the drain extension appears to have been welded onto the iron stub-out. The question is 1) how do I remove all this and 2) how...
