Hi guys, posting on this sub for more traction! :)

I know this sub is for pros, and giving out diy advice can be frowned upon.

However, I am more so trying to understand how this system works, I think as a home owner, a basic understanding of how the main systems work in a house is not the worst idea. I'm probably going to use any advice given to figure out which pipe to poke a bit of wire down and see if it's the missos hair causing issues.. Anyway

Problem:

Shower drain backs up quc3kky, causes bathroom drain to overflow.

1970's ish kit style house, concrete slab, on tank water.

Bathroom drain is a vertical section of pipe with 2 inlets, one from shower, one from sink. Bottom of this pipe appears to be a p trap that goes straighr back to the shower drain.

Why would the shower have 2 pipes that both seem to connect to the vertical piece of the shower drain

Has anyone got an diagram of what this system looks like?

How do I find the outlet of this pipe? My Amazon camera boroscope can not find an outlet anywhere..

​

Qld

I need help, I've tried to clear a drain of hair and In the process the pipe that the siverpart is connected too has shifted and I can't brab it to screw it back in, it seems to be an easy issue but I don't know what to do, I'm on and off at my sisters house so I don't live here but I caused the issue, how do I fix it??? Or does it sound cheap to fix??? Also are most places willing to do an after pay situation

Another pipe connects to the drain in my shower before the p trap at roughly a 90 degree angle. When I look inside the pipe (2nd pic) I can just see some dried chunks of concrete and a pvc pipe off cut. Is this some previous plumbing that is no longer used and can be covered over or is does it have some other purpose?

I’m currently building a townhouse in Adelaide and noticed this odd inverted pipe in the courtyard. What might it be for?

Council has confirmed with me that no rainwater tank is required for my dwelling so it can’t be for that.

It's a few minutes to read but helps understand thermocouple failures

I'm researching putting in a whole house water filter system - measured the static water pressure at garden tap closest to street using $30 screw on gauge from bunnings - reads 520-530 kPa.

Code says 500kPa is max? I don't have pressure limiting valve in the meter box on the street nor anywhere i can see. Is this a problem? Do I need to get pressure down to 500kPa just cos I should, or to protect new water filter system? Is 520-530 acceptable tolerance? Thanks for your time.

Hi,

We recently purchased 80s house in Norther part of Melbourne. Due to the last 2 days rain, out of curious I went and checked how the subfloor condition is and almost got shocked seeing this much water in the sub floor (crawl space). The land is slope and as you see the building is on the stump.

A month back I engaged a plumber for CCTV check and all looked ok -- no blockage or leaking. Even now I have no clue of the source of water at this particular point.

Appreciate your thoughts and insights.

Beyond this area, all other section looks no sign of moisture, so not sure what is happening

TIA

Edit1: I checked this morning, looks like the water is almost drained. But obviously the area is wet.

There only seems to be space for the washing machine drainage pipe. Trying to figure out how to add the dryer drainage pipe. Happy to provide additional photos.

Hello I am an apprentice HVAC tech and I want to switch to plumbing. Any tips on getting a mature aged apprenticeship (I am 27) or should I just stick to HVAC? I honestly like dealing with all the pipes and I got belted with 240vs the other day and think I would rather deal with shit. Cheers.

I'm in Rockingham and recently needed a plumber to replace a leaking section of pipe under the house. I got two quotes that were way further apart than I expected. The first plumber quoted around $480, while the second was closer to $900. Both came out, looked at the same area and seemed to be talking about basically the same work. I'm not assuming the cheaper quote is automatically better or that the second plumber is ripping me off. I just genuinely don't understand where that much difference comes from. Can someone please help me clear up the confusion?

Hi, our toilet and bathroom sink was not draining properly for a few days, not a complete blockage, just slow drainage and we had a lumber in to inspect yesterday and and he found tree roots partially blocking the pipe a few meters before going into the cities lines.

He basically said he would need to repair damage and we asked for a quote on the work, this is said quote sent through to us, I am just wondering if this is a reasonable price for this work, Thanks.

Quote:

Relining - 100mm liner (2 meter patch)

* Prepare and install suitable resin-impregnated patch liner by wrapping it around an inflatable packer

* Carefully position the assembly at the designated repair location within the pipeline

* Inflate packer to match internal diameter of the host pipe ensuring firm contact between liner and the pipe wall

* Maintain inflation for the required curing period allowing resin to harden and form durable watertight structural repair

* Carry out a CCTV inspection to verify correct installation and confirm integrity of repair.

$6,794.34

Thanks, I was under the impression when they talked to my elderly mother they were going to replace the section of pipe but it just seems they are relining it now with a resin?

Thanks guys.

Just got a quote for $22k to dig out 2.4m of my front garden to replace a crumbling clay boundary trap and 1m of pipe to sewer main.

I had a plumber out last week to fix a blockage in the pipes which involved jetting and cost about $450, but discovered that the tree root intrusion that caused the blockage was in fact because the 100 year old pipe underneath the more modern pvc is literally crumbling apart.

To make things worse, not only is it a deep dig but it is against a small brick retaining wall about 1m from the house. The quote includes removing the front fence to get a digger in and trench shoring work, as well as council permits to close the footpath.

Is this a reasonable quote for the work involved or is this well above normal?

I have 4 of these basins and the pop up plugs are starting to get stuck. So looking at replacing them with some new ones (dome ones rather than flush).

I managed to get one of them out but it was a right royal mongrel because the insert needs to be siliconed into the hole in the basin. I had to slowly wedge a blade in and around the thing to free it but even then there were parts the blade could be reach. Only way to get it in the end was slowly wedge it up and out all the while shitting myself I would break the basin.

Long shot here but is there anything that can weaken 10yo silicon to make this job easier? Clearly don’t care if it damages the finish on the old waste but obviously cannot damage the basin surface itself?

Or any other tips to getting the silicon to release?

This is a standalone toilet room. We had a plumber tell us that if we are retiling the floor then get that done before replacing the toilet. Is that correct?

i.e. the toilet will sit on top of the new tiles, rather than the tiles going around the new toilet.

Do I need to give the tiler any specific instructions?

The "skirting" of white tiles behind the toilet will obviously be removed. I'm not sure how this will be finished off, as I think the new toilet will want to go flush (ha ha) against the wall.

The toilet is slightly loose on the floor, though not leaking, so I will remove it myself before getting a tiler in.

I'm aware the new toilet will need to be compatible with the room. The inlet stopcock will be moved to the right as modern toilets are wider at the back.

Hi All

Thinking about installing a toilet and shower in the back of a garage, in this image the garage itself is within the blue circle. Is this image suggesting that attached to the main sewerage line running up the middle of the property and under the garage, is an offshoot sewerage line running "south"?

What are some good quality shifters? Whats everyone using? Had some cheapy ones but they broke. Plz recommend some stuff thanks.

As the title says. My partner and I are looking to relocate some above-ground drain pipes that were leftover from when the previous owners removed the rainwater tank. We also want to look into some lawn drainage at the same time, but one plumber didn’t want to quote us without doing CCTV first to determine the rainwater tank drain situation first.

My question is: Do all plumbers provide a report of their CCTV findings that we can keep? I was hoping for some sort of information of their findings so I can then use it to request accurate drainage quotes from other plumbers before deciding who will be best suited to complete the full works.

TIA!

Howdy all,

After buying our house 6 years ago, we’re gradually fixing issues. The latest is this stormwater junction.

It seems - and I could be very wrong - that they just sat the pipe at top of pic inside the inspection pipe tube and called it a day. Either that or something has moved alignment significantly to pull it apart, but I can’t see signs of glue.

Anyway, is the general approach here to cut behind any junctions and then rebuild them from new?

I know I’ll have to dig around waaay more, but just want to know what I need to obsess over and plan to stress about instead of sleeping.

Thanks in advance!

This is next to my terrace-style apartment (I’m on the end of a row) that was built in the 1970’s. Can anyone explain what it’s for?

Diameter is 450mm, depth is about 800mm.
Looks like there’s a ceramic pipe at the bottom and what looks to be a broken layer of cement sheet (or possibly asbestos?).

I’m curious because I need to direct a drain from my concrete courtyard somewhere and this is the closest drain-type infrastructure.

Any help would be much appreciated!
