Repairing bathroom floor... again
Comments (14)You wrote: "The custom shower floor included a vinyl pan, mudpack, mastic...then grouted tiles. " Find out what specific adhesive was used to attach the tiles to the mudpack. There is "mastic" and there is "thinset". Some use the terms interchangeably, but they are very different animals. Mastic is a premixed product, it's thick and goopy and usually white colored. Mastic will come in a resealable plastic tub. Mastic is water soluble and pretty much every mastic maker specifies that it's not to be used on shower floors. If your floor gets wet, which would be expected in a shower floor, the moisture can soften or re-emulsify the mastic. That could be why the tiles are losing their bond and why tiles and grout are coming loose. Thinset should be used to bond tiles in a wet environment. Thinset comes in bags as a dry powder. You mix it with water. Thinset is portland cement based, so it cures hard like cement. Once cured, water has no effect on it. If mastic was used, that's dreadful. One other thing again based upon your description: Your vinyl membrane below the tile should have been installed on a sloped mud bed so the membrane itself is sloped to the drain. That's a building code requirement under the IRC. In general, the main components of a shower floor from bottom to top should should be: subfloor, then sloped mud, then the vinyl membrane over the sloped mud, then another layer of mud on top of the sloped membrane, then tile. If the membrane is flat on the subfloor, that can result in the membrane holding water and your floor staying moist. That moisture would exacerbate the problem if mastic was indeed used....See MoreBathroom Sink/ Drain Pipe (Drain Pipe broke leading to ground)
Comments (4)The first thing i did when I could find a hole was stick the broken piece back under the sink and held it there, trying to find all possible position, from the ground and had no luck. Someone had mentioned a Branch Arm connection.... I did look left, right and up but did not put much effort into the search because I thought that was not possible... I will look a little harder... Also I am not sure if this helps but behind this bathroom, or behind where the break happened, there is another bathroom in a separate room. In that bathroom there is a stand up shower that shares the same wall as the sink in question. I see numerous water supply pipes.... but no drain pipes... Thanks for the follow Ups so Far.. I posted on other sites and people are less than happy to help most thought this was a joke......See MoreSewer smell from bathroom sink drain mystery
Comments (46)Thank you David! When having this house renovated post purchase, much of the bathroom was gutted and the sink I had installed is one I bought new some years before and was waiting to use (American Standard Standard Collection Console sink with oval glass shelf.) Because the works underneath are totally exposed I bought the best chrome P-trap and fittings a local plumbing supply house had. In a month or so I'll have my plumber back to install a pump for my utility sink, and he will need to add another vent stack I believe, so I'll have him see if the sink is connected to the bath vent, and if the vent has any blockage. I'll ask him about the air admittance valve - thank you so much for that information!...See MoreMissing flooring & drain connectivity in bathroom
Comments (6)I know what you mean when you asked not to be judged... I heard lots of horror stories about Rayan home developments. Are the 1st 2 pictures of the shower pan and the lower 2 pictures of the bathtub? What state are you in? Some states require 1-3-10 homeowner warranty, that crack that you show could still be under homeowner warranty I would have that replaced. If not and you tight on money, you can repair that crack, they will tell you right away if it can be fixed. Most local plumbing supply stores can give you a contact number who specializes in these repairs and they do magic. As the drains go, the 1st picture the drain seems fine, the 2nd drain for the pan I'm not sure about that one, I would have someone check what is on the other side of that notched joist and how far is the drain from there, not to mention the notch itself to make sure it is code compliant....See Morempelescak
