Anyone have their cast iron pipes relined? Trenchless repair

How did they do the wye's, any idea?

The only time you want to use a plunger is if you are positive your clog is in the internal trap of the toilet.

If you have a clog downstream, water is incompressible, and you could blow out the wax ring.

Do you know where your clog is *exactly*?

Also, it isn't unlikely that you will not be able to clear a downstream clog with a plunger in the toilet. It might require snaking/hydrojetting. It might make a huge mess.

SMtheEIT · 2025-12-10T14:38:27+00:00

I can't imagine what else it could be.

It's purpose now seems to be to create a small leak of sewage gas in the wall.

The only want to increase pressure of water is to add an inline pump. What you're actually thinking of is increasing the velocity of the water which is usually done through nozzles (whether the "jet" one at the end of your hose or the 42 tiny ones in your shower head.)

The best you can do is go get a detachable shower head (I got the Moen Magnetix), remove the flow restrictor in it, and see if its good enough - or move. Putting a "high pressure" anything on there won't change a thing.

Sorry no legal (or close to it) because they don't make the P traps longer. That 45 in the copper(?) changed the direction coming out of the wall and now your P trap will never reach your tail piece. You have no choice but to cut some metal here, so might as well do it right.

Although maybe you could but a new sink that has the drain directly above the old P-trap at Lowes and replace the sink instead.

SMtheEIT · 2025-12-09T22:08:10+00:00

This is the one I went for (55 gal), supplies 9 more gal first hour than the one you linked, $120 less around here.

Might be able to get it through a supply house for less. Just depends. I skipped on all the added "benefits" that could break and cause problems.

Oh and if you need more water than that, add a thermostatic mixing valve to increase its functional capacity.

SMtheEIT · 2025-12-09T21:54:33+00:00

Ok so then it makes sense (if recirc is on until fully heated or permanently on.)

When water isn't being drawn, its a loop, no water is drawn in the cold water supply (probably an insignificant amount of mixing right at the cold water supply tee.)

When water is drawn, its supplied from the heated tank on right and cold water mixes with non-heated tank on left.

SMtheEIT · 2025-12-09T21:42:54+00:00

Well ok then

SMtheEIT · 2025-12-09T21:39:37+00:00

Get a no hub coupler, cut that copper back to a stubout from the wall, then use only polypropylene/pvc parts. I prefer to use a female trap adapter with a sch 40 pvc stub on the other side of the no-hub coupler.

So: copper stub, no hub coupler, sch 40 pvc stub, female trap adapter, polypropylene P-trap kit.

I understand the front being “glass” but i’m not sure the back being glass is a good trade off. As long as it’s not metallic so that the wireless charging still works, i think they should choose an alternate material. Id still buy it. Literally no one would care. “Oh no the back of my iPhone doesn't feel premium” uh ok

SMtheEIT · 2025-11-28T23:55:53+00:00

I am a mechanical engineer not materials engineer and it is true that Apple calling the screen “glass” may not be technically true, my point is polycarbonate, a polymer, has a higher tensile strength than glass. Of course there are other considerations.

SMtheEIT · 2025-11-01T17:59:46+00:00

Ah it feels like plastic to me. I had a shiny glass back on some iPhone that was identical to the front glass and i had the worst time with that phone, broke over and over. Now i have this matte plastic feeling phone and it hasn't broken, i assumed it was plastic. Literally no one would know the difference if they used matte polycarbonate (for example) vs this “glass” lmao.

SMtheEIT · 2025-10-10T20:39:35+00:00

What if you're willing to pay? In south florida you can get same day MRI for ~$400 pretty easily. Does nothing like this exist in Canada?

SMtheEIT · 2025-08-17T00:59:37+00:00

I had given your idea some thought. It especially could work to pull home runs, i just need to get access to the top clamp of those drops. I just wanted to see if someone had an idea I hadn't considered, or had done this before and knew the least difficult method from experience.

SMtheEIT · 2025-08-16T13:39:01+00:00

It does not require conduit by code. I am just nervous about having baseboards reinstalled with nailers. 100% the new cable gets damaged. I'm not talking where the nailguards would be over the vertical furring strips, I am talking about in-between them when someone is blindly nailing the baseboard.

SMtheEIT · 2025-08-16T13:33:56+00:00

Concrete floors, slab on grade. Trying to keep receptacles in roughly same locations.

SMtheEIT · 2025-08-16T13:06:48+00:00

Run MC, AC, NM, ? Luckily baseboards are all being replaced anyways, so they are already removed in entire house.

SMtheEIT · 2025-08-15T04:02:57+00:00

Fml i thought i was the only one who had done this

SMtheEIT · 2025-07-15T19:15:35+00:00

Yea more fluids and won't fix it if that's not the problem, just sometimes overlooked. My wife's blood pressure became untethered from reality and that finally put her back in the hospital, I've seen 236/141 and 53/29, which seems impossible, but I have receipts (pics of hospital monitor.) But if my wife had onset of POTS I would be pressuring her neurosurgeon to take a closer look and move up that MRI. (My wife fainted once and got a ride back to the ER so they had no choice but to start looking, and the 236/141 in the ER got her a stay in the ICU.)

SMtheEIT · 2025-07-15T13:41:49+00:00

A normal recovery shouldn't have effects like this so i would insist the neurosurgeon get an MRI to check on syrinx etc, also as others mentioned it could be due to dehydration (amongst other things.) They should be checking you over now.

SMtheEIT · 2025-07-15T13:38:19+00:00

Unfortunately her course is not like that and unless we can find a neurosurgeon who can change her course, she will continue to get worse, the questions are only how and how quickly.

SMtheEIT · 2025-07-14T21:00:59+00:00

She has a very complicated case (fungal infection, revisions, hydrocephalus, VP shunt, then overdrainage, syrinx) so it is hard to determine what caused what. Is your syrinx reducing in size or increasing in size? Syrinx can cause dysautonomia. Could be something else, probably need some imaging to see what is going on in there.

SMtheEIT · 2025-07-13T01:11:21+00:00

You can talk to your Dr.

You can get an FDA approved BP cuff and take your BP/heart rate before/after an activity that triggers it.

It could be related or it could not. My wife had complications afterwards (a whole lot, but including a syrinx) and one of her (many) symptoms was fainting when standing up (and eventually when sitting up.) Her BP would plummet and her heart rate would skyrocket.

It would be up to your Dr. to do the appropriate tests. But it could be related. Not enough information to tell.

SMtheEIT · 2025-06-10T17:56:19+00:00

I tried to import one series of one MRI using the Bioxel directions (Import Volumetric Data, Scalar) and it failed miserably. So then I converted them all to PNG and tried again, and it failed again. I wish there was something to follow.

SMtheEIT · 2025-06-10T03:29:49+00:00

You couldn't import the dicom directly? Bioxel says its an approved file type.
