can water lines for toilets be separate from main line????
Comments (13)I had both hot and cold lines open on all fixtures throughout the house. Everything loses all pressure after the lines clear and water stops coming out of everything. But, I can flush these 2 toilets over and over and they refill at presumably normal pressure levels (I don't have a pressure gauge I can attach to the toilet line to test exact numbers, but the tank fills at the same pace as normal). The water in the tank is cold as it fills, as well. If there's no code exception as to why they did this, I have to suspect the plumber somehow pulled a line from the the supply side of the water main. My neighbor (referenced in my first post) got $35k in damages. The toilet tank overflowed bc the float switch broke. My theory I'm going to work to prove is that bypassing the main also bypassed a pressure regulator, which causes the high pressure to break the valve. Our houses were built in 2017, just for reference. Some of his walls have been opened up to remediate the water damage, so I'm going to see if I can go over there and trace lines. Thank you for your suggestions and help!...See MoreIn-line water heater--ruptured copper tubing
Comments (9)It definitely could and in fact the discoloration around that area and the pattern of the hole looked to me like an electrical arc pattern more than a pressure leak/blow from the inside. It just doesn't make any sense that that copper would fail with a "pop" in such short time after installation. I'm no expert, but the walls of the copper around that area look normal thickness and if it was a burst from internal pressure I would think the pattern seen would be more outward and (from what I've seen in past) linear, not in a clean arc like that. Fascinating. Hopefully others with more expertise will chime in and I'd have the whole unit looked at personally before I'd trust it - if there is something wrong with the copper the same thing could happen in your wall or somewhere else. If there's something wrong with the electrical wiring or unit itself, that could kill someone....See MoreCopper repipe or Pex repipe for 10 unit building?
Comments (7)The HOA is doing it and I'm on the HOA. The building was built in 1961 and it has galvanized water. I think we're going to share the meter. Not individual. This should keep it cheaper. My main concern at this time is how soon the system would degrade? Which would last longer PEX or Copper? Seems like scientists say PEX last long, but it's only been around in california for a few years. I've seen first hand copper corroding with pinhole leaks after just 20 years, but I don't know if that was just a fluke...See Morecopper, cpvc, pvc for main supply inside
Comments (1)By code definition a "Supply Line" is the line from the municipal main or well to the structure. All lines inside the structure are defined as "Distribution lines". The "Main Water Shutoff Valve" is the official point of demarcation between Supply and Distribution lines and is usually required to be located within 6' of the point where the water enters the structure. PVC may be used for Supply piping but it may not be used for Distribution piping. (may not be used inside the structure after the main shutoff valve). To prevent electrolosys Code prohibits directly coupling copper to ferrous metal(iron or steel). You must use a dielectric nipple, dielectric union or a 6" hardened bronze nipple as a transistion fitting. You may use brass or bronze nipples. Your options for pipe are Galvanized iron pipe, copper pipe, CPVC or PEX(if approved by your local code). If you use CPVC you must allow the glue to cure for one full hour before turning the water on....See Moreshacko
