We're using Uponor Fastrak elsewhere but this section the bay is just 2ft long so this is how I handled it. Look good or no?

Is it acceptable to use a regular 1/2" straight coupling to cut out damaged wirsbo PEX pipe or to extend length of a hydronic run? Or are people purists about a clean home run, redoing a run as needed with continuous pipe? If so, how many would anyone use in a run?

Is there any good alternative source for Uponor transfer plates? We had Uponor do our layout so I assume its all figured based on their transfer plate performance but that turns out to be a huge portion of the overall costs so wondering if anyone else makes a comparably performing product for a...

I have a 2" floor drain going into a 2" p-trap and then on into a 4" main drain in the basement floor. In order to keep the trap wet over time, I did a wye off the floor drain vertical and dropped a lav sink into it. The lav will of course have its own P-trap and vent in the wall as normal. What...

Single family 4+ baths. Will have two 4" building drains coming together and then out to sewer. Original sewers around here are sometimes 6" terracotta. We'll have not only sanitary drainage but also gutters (allowed by city) on 5000 SF house (1200-1500 SF footprint) Thoughts on 4" vs 6" from...

The application is actually a 4" sch 40 pvc foundation drain. To get Max perf drain pipe at footing went with LT 90 instead of 2x45s. CO isn't usually done in foundation drain to begin with, but just wanted to see if it is self-deafeating if 4" rooter can't get thru.

I have some American Standard fixtures that both require screwing onto a nipple protruding from the finished wall. Since the tile guy ends up with the final say over where the finish wall ends up, it looks like two of these ended up wanting a nipple between the available sizes: a shower arm and...

Hi Attached is picture showing joint between a 4" wye and the downstream pipe, which is side sewer run of SF residence. It's bottom of a decline. It's a bit hard to make out because of excess glue, but the joint has about 1/2" gap at bottom. Top of pipe is tighter at the joint. You can see...

I need an ASSE 1070 compliant mixing valve at point of use for a free-standing slipper tub supply (3/4" supply lines btw). What products are recommended? The supplies are to be floor-mounted; how have you handled access for the valve in this scenario (I am thinking about building a box above the...

How should a pressure loop be laid out for case where valve is in back wall, and two sets of two body sprays are opposing each other on both side walls? Can we run a loop in the back wall and run feeders off to sprays on each side? If so would we run four direct feeders or two that split...

if a house is fed by 3/4 galv pipe that is quite old, probably corroded inside how would that affect the pressure at the entry? We are seeing relatively low pressure now wondering if we replaced the supply to the house from the street with new 1" Pex would we see an improvement in pressure?

Help: have to choose lesser of two evils slope or structure.... 2x8 joist space coming off tub drain we have 1-1/2" CI ptrap as high as possible with plastic street sanitee going direct into ptrap via 1-1/2x2 Fernco proflex coupling. windows in wall below so running horizontal in joist space...

Just saw that UPC wants no pipe within 45-deg of the foundation footing. In the attached photo you can perhaps see that I didn't know that when I laid these pipe. So, they are within that downward angle... is this something that will very likely get flagged or ignored on inspection? Obviously a...

ABS pipe is not supposed to bottom out during dry fit in fittings. However, if you dry fit a few times (for example to work out a complex geometry) or wiggle the pipe in the fitting a bit it seems like the joint often gets loose enough to actually bottom out, or nearly so. The fittings are...

Seattle says to use either astm 1575 or astm 3034 pipe for side sewer lines. The heavy duty 1575 is for less than 18" from surface. (Confusing to me, I'd have thought heavy duty for more earth atop!) Anyway, our plumbing stack is being relocated and after passing under foundation wall, we're...

What needs to be done to run ABS under newly poured concrete slab perimeter in terms of protection for the pipe? What about ABS penetrations through the slab? Do these need to be wrapped with a sleeve and if so what sort is it? Also, is it the regular ABS or something special? Also, for...

We have a claw foot cast iron tub that has feet attached by bolt to the bottom. Each bolt has a wedge-shaped head that each sit in a pyramid-shaped channel. One of the pyramid channels is broken on one side. We have tried to repair with JB Weld epoxy but it is not holding. While concerned about...

Not sure where our calcs went wrong but we've got an American Standard R540 valve installed--very difficult to move at this point!--and the tile guy says that the tile will end up about 1/8" proud of the Max dimension on the plaster guard. I understand the meaning of Max... but is there likely...

Finally broke down and had a plumber come by to see if they could quickly install a cast iron tub and a steel tub for me. They wanted $3500 so I am back to DIY mode. One tub is cast iron and will go into a bath on second floor. I had run CI drain and p-trap which was set too high (for the tub...

We just did our pressure test for the DWV system. It is a two-story house w/ basement and there is a lot of 4" cast iron. We filled up through the roof w/ water and it was holding for over 2 hours awaiting the inspector. Anyway, by the time we were done he noticed a coupling at the bottom of the...
