have the main line professionally cleaned out. Then have them run a video camera down it.

yes.

generally that white stuff is zinc and magnesium oxides that have fallen off the anodes as they work. FWIW the warranty difference between different water heaters in the same line is usually the number of anodes they put in the water heater. Once that anode is eaten away, the water heater...

Thanks everyone. The flooring guy is here on the second bathroom. It too has an aluminum flange. Has a little corrosion but minimal compared to the last one. Hoping to be able to use it again without replacing it. I gifted the Reed tools to my plumber who is booked today if the bolts fail to...

closing this out. My licensed and experienced plumbers were here this morning upgrading the 45 year old clean out that has rusted to where it snags things. My main plumber took a look at the flange while here, and replaced it for nothing. We used the Reed cutters, they worked well, just a...

Thank you. I found one article by Quikrete that suggested the quick-setting cement is best for under the flange than the anchoring or hydraulic cement. I would have thought otherwise and they did not say why. It requires a bit more prep. Compression strength is 2000 psi after 24 hours. I don't...

with anchoring cement or hydraulic cement how many hours to drill holes in it do you think? By the time I set the flange, get it in place, and push screws in, the cement would already be setting up. I also have a bucket of Quikrete Quick-Setting cement on hand already that sets up in about 15...

1994 - replace it. Average life is 10 years with you maintaining good anodes. I get 20 years and then replace on good practice. You can choose to replace it on your timing, or wait until it forces you to do it at a time when it will get in the way of other things more important. With inflation...

most expansion tanks have to be checked once in awhile. To do so one needs to know water pressure in the system, and have an ability to turn the water off, take the pressure to zero and charge the tank to the same pressure as the house system. I check mine once a year - and they do not last...

Thank you. Will do. I went with the Proflo flange. It is a good quality builder grade ASTM 2261 DVW ABS whereas the Sioux Chief is more robust. The Sioux Chief knockout takes a lot more hammering to break it free, and this is 45 year old ABS. I could knock it out before installing it but if one...

Thank you. Will anchor it the best I can. Concrete is temperamental in that area. I guess I could pick out any lose concrete near the flange, use some hydraulic cement to fill any voids, stick in stainless or tapcon screws, pack down and then hope for the best. I used a 5/32" SDS bit for 3/16"...

We are sort of in a bind to get this resolved asap -it is holding several other parts of a project up along with those contractors. Thanks in advance.

Have to replace at least one ABS toilet flange in concrete. I believe it is an inside 4" outside 3" that was used about 10 years ago to replace a 4" outside original from 1979. I have ordered Reed tools to remove the present flange. My plumber has been busy and evasive on how he wants to fix it...

coming back to update this thread. Last month I noticed that although the PRV was working, it had about a 1 1/2 to 2 second delay in adjusting pressure when the washing machine came on so I rebuilt it again with a new kit. The pressure would fall way down then pop back up and hold steady. It...

on mine there was a hard rubber seal that was driven between the pipe and the pan. That sealed it, looked almost like caulking but it was a seal. Had to dig it out with a screwdriver blade on mine. Yours may be different, I don't know. Like this...

:) - whether they can be rebuilt depends on whether parts are available and the price. It also depends on the quality of the water. Here we have water from annual snow runoff in the Sierra Nevada Mountains. It is not mineralized like some water is so there is very little damage to the valve...

no, the old one was not fine. The valve was quite stiff, almost un-moveable by hand, and the pressure swing as a result caused a very large drop in pressure before the valve responded. Now the drop is only 7 - 10 psi and holds steady when the washer comes on. It was 20 - 25 PSI with a several...

Have you replaced both the toilet valves? Is it only the bathroom devices that are hammering? I know when researching our hammering, I read many places that when toiler valves get old they cab chatter and that causes hammering. Example: https://www.inman.com/2009/09/16/flushing-away-water-hammer/

conclusion - the valve was sticky and took a lot of effort to move the core once it was out. With a new kit the PRV responds almost instantly now. The lag was caused by the sticking internal valve. I know how they work, just did not know if a lag is normal - it is not. In my experience the...

I am going to just rebuild it and move on. I don't even think that many professional plumbers come here because no one seems able to answer the question, "how much lag time does a residential PRV have? This one is about 1/2 to 2 seconds before it opens and lets the set pressure back in. It...
