im installing a bunch of wall mounted lav faucets which I have never done before. Just wondering where and how the shut offs are usually plumbed. My thinking is that you just come out of wall, have an in-line ball valve, then go back into wall and tie into the rough in. Is this how it’s done...

According to Canadian NPC, provision must be made for thermal expansion when check valves or pressure reducing valves are installed. Is the T&P relief valve sufficient to meet this requirement? Or must an expansion tank be installed. I always install an expansion tank when check valves are...

Anyone know of any sure fire ways to tie ABS pipe INTO the hub of old hub and spigot cast iron pipe? I've seen a few ways online but wanted some plumbers who do a lot of service or residential reno's advice. I think Fernco makes a gasket, and I've also seen someone who used oakum and hydraulic...

I am installing a Watts 2" RPBA. I have it installed at 6'4". I know max height is 60" unless a 'permanent platform' is built. My question is what is the definition/purpose of a 'permanent platform'? I have heard two differing opinions. One is that a platform is req'd solely for the testing...

i worked in re-pipe for years in Vancouver BC recouping big and small apartment buildings. It is a profitable market in that sense. I have a friend who wants to do "residential re-pipes" and something tells me it's just not worth it. Seems to me that most plumbing companies already offer re pipe...

I have not gone to look yet, but from what homeowner explained over the phone, one shower he could "walk around in for 4 hours and barely be wet", while the other one is "like a pressure washer." It sounds to me like it is a back-to-back setup, and the diverters are Moen's. He sounds like a guy...

The way I was taught was to always put a vacuum breaker above the hot water tank, on the cold supply, theory being if a vacuum was formed it would be broken before siphoning the tank dry. That's my understanding anyways. But I bring this up because I am with a large mechanical company working on...

Not so much a plumbing question as it is a business one. I don't do a lot of side jobs but have a big one coming up. The issue I have is since my experience is not in residential I have no idea how much to charge. I talked to my brother in law who is a plumber and he charges materials + 30% mark...

should I use Sch 40 or Sch 80 pvc for the discharge on a sump pump? Am installing a liberty p382le41.

In Vancouver, BC. Can someone please tell me the specific code requirements regarding laundries? I need to rough-in a washing machine and laundry tub and would just like any specific code requirements to help me plumb it the most efficient way given the situation. I know code has recently been...

does anyone use double wyes to plumb a typical bathroom group? I have seen them used 3" center ports w/ 2" side outlets, toilet obviously on the 3", and one port directly to shower and other port to lav with the lav wet venting all the toilet and shower. My question is, is it allowable to use a...

I'm just curious as to how you guys plumb showers in a basement. Is it okay to box out a 12"x12" square in the approx area of shower drain and stub up in it? Then any slight offsets could be done after concrete has been poured? Your input would be greatly appreciated. Thanks.

I know 90s cannot be used to transition from vertical to horizontal, but can they be used vice versa? Line in question is a 4" sanitary line draining an upstairs bathroom group.

I am looking at doing a Reno for a friend of mine who is redoing the basement. Upon inspection I noticed his current downstairs set up drains out of the boys about 6" above the slab, and his upstairs drains out of house about 5' above the slab. Current basement bathroom is built up about 12"...
