 Topic: Plumbing Xperts?
Posted: 08 Sep 2021 at 9:41am |
Oh, I've never been able to do a job with pipes. I always called Emergency plumbing because once I tried to make a pipe myself, I then had the floor of the house in the water. Since then, I no longer do plumbing. And apparently, you have the same situation, haha. Friend, don't worry so much. In my opinion, it is better to call professionals and let them deal with such things. Yes, you will have to pay money, but at the same time, you save your time and nerves. Well, everyone has their own. I just expressed my opinion on this matter, and I hope someone shares my opinion here.

The worst is a clogged urinal drain. That's all I got to about that

I am not so strong at drain blockages. From my point of view, I believe that these are the worst plumbing issues that can appear. I got a massive headache due to this problem. I tried to solve it with my own hands but with no chance. So, I decided to call the guys from one of the best plumbing services in Sydney. They sent me a team of experts that resolved all the questions regarding plumbing needs. I am very thankful to these guys because they saved me from big wastes. Also, they held a lot of my time.

Put in a Keep Warm loop in our Hot Water system when built, Laing pump and timer, can adjust for Water temp on return side for shutdown. Insulated the Outbound pipe and return leg, runs 1/3 the time as uninsulated. Cool water when first turn on shower or bath faucets, takes but moments and already warm, at temp less than a minute in either upstairs bath.

they also make a small point of use hot water heater one can install under a sink and runs on 110 v - friend has on in her kitchen so has instant hot water . Have thought about one of them .

Took me a while to wrap my head around that one, but can see how it would work. A way to graft a hot water circulation system onto a house that was not plumbed for one when built. But other than that, can't see the advantage. Pump on timer or temp sensor would work either way.
This house, which was plumbed for the circulation system has a first level loop that goes to all hot water faucets on the ground level. Two bathtubs, two bathroom vanities, plus kitchen. Instant hot water to all.
But now that this one is working, we are finding the same issue with the warm cold water. Cold water lines apparently plumbed parallel and close to hot water lines, which despite being insulated, over time will still warm the slab they are running through. So hot water is circulating, but cold water is stagnant until used, so instead of staying cold, cold water in the line is being warmed to slab temp, just as a stagnant hot water line would get cold.
What I have discovered, however, is how pleasantly warm it is to be standing on the section of floor where those lines run.
This is the first slab on grade house I've ever lived in, and I must admit, I'm not a fan. But if I was going to build one, it would be great to utilize the slab with a hot water radiant heat system.

Laing has that type you mentioned. I put one in for my cousin a couple weeks ago. It's a point use type. Went in cabinet under kitchen sink where there is a 120v outlet already. Has 24hr timer as well as temp sensor. He loves it. It works by pulling hot water from the hot side and sending to the cold side back to water heater and shuts when temp reaches 95 degrees. Granted you might have to wait a bit for cold water to fill a drinking glass but for his purpose it works great and is planning to get another for a vacation home.

Seems rather than a timer or along with a timer a heat sensing thermostatic switch could be added so it would turn on at some low temp and turn off when hot water is sensed on line temp equaling water at desired heal content in the return line .

On the bits of cast iron, that was confirmed when I starting purging air from the hot water lines. Bathtub in guest bath that rarely gets used, dumped a bunch of what looked like fine iron particles, plus some pink water, which may have been rust forming in the line leading to that faucet.
So I'd agree.....between the high volume pump, thinner type M copper lines, and possible corrosion from mixing metals, that whole thing was a mess. Would be interesting to know what the thinking was of the guy who installed it. Was like that when we bought the place. Been trouble the whole time we have been here.
We did replace with the Grundfos UP10-16 pump with brass body. Is working well.

Epilogue: Went on a quest and found this 2 or 3 gpm pump at a local plumbing supply. If you think $320 is pricey for that pump, I'd agree with you. They also agreed existing 17 gpm pump was running way too much volume. Should have been on a large commercial or industrial site.
Anyway, swapped out pump, plus all the old patched up pex and copper plumbing with new type L copper, turned it on and it started cooking. Takes nearly 90 seconds to make the loop, but even that low flow is plenty to deliver instant hot water.
So thanks for the helping solve my problem! At least one thing we talked about ended right this year.

Our softener, Laundry and Kitchen Sink discharges go to a Gray Water Drain field, no need for septic when put bleach and salt down that drain, all biologics DIE in that trench/French Drain

whew... glad that those pipes are PEX !, sigh of releaf... My weater softener is an 'on demand' style... regens based on actual water uages NOT a 'time clock'. I don't go though mush salt... my 'salty' water to the weeping tile bed.. I was going to plumb it out to a 'drywell', sigh , that was , um, ahh.....20-25-30 years ago.... maybe, one day.... Interesting note, plans for new house next door , say on plans....'NOT to have water softener drain plumbed into septic tank'... You can usually 'dial in' the amount of salt. maybe just reduce by 25%, see what happens to 'soapy hair test' , lotsa bubbles, reduce some more...

Good news on this front. Went on a quest and discovered that all risers I can get to coming up through the slab are in fact PEX......hot water lines even wrapped in insulation. So probably safe to conclude the hot water circulation loops are also PEX, so probably OK to replace high flow pump with low flow and be back in business.
Comments on sodium........water district is known for having hard water..........so everyone has water softeners. Mine is a Kinetico. It goes through a lot of salt. About 40# per month. My question has always been where does the salt go? Flush cycle water goes into the drains. Does that mean my septic system gets salt.....or what had been NaCl that is now tied up as something else?
Lines to faucets that you might drink from.......kitchen and line to ice maker.....remain hard water. That suggests to me a lot of the salt (sodium) must end up in the water domestic use water? Source of sodium?

K99, because the more purified the water, the more it attacks metals and absorbs minerals. RO is extremely pure, and begins to dissolve any metal it comes in contact with and therefore copper would not last long at all.

Looks like from the picture of the 45' fitting, you have high sodium water. Going to a reverse osmosis system will solve your problems.

So long as NO air entrainment and low flow erosion in any water line will be minimal and Take LOADS of time, will generally take a point of a turn to burn thru. Parents house had a recirc pump, pump died twice in thirty pus years living there, NO Piping destruction. Iron or Steel flanges, copper fittings, Plumber here used Sweat Solder Ends for installing our pump(Brass), NON ISSUE in over five years running, lost a timer once so far.
Is a Ecocirc ITT unit. Sis in law stays a few weekends a year, enjoys that timer and temp setting side program keep her shower at seconds of delivery time to hot and at 50' from water heater. Did add insulation wrap to the piping after installed as AC time would chill the utility corridor area of our basement and make the pump extended run.

I did in-laws house trailer in PEX to get away from the steel-copper piping in the crawl space.. Took paneling off a couple walls to install some... then ran across the ceiling in bathrooms and laundry room... built a FAKE wood beam to cover the tubes afterward... Worked great.... 45 years old so was a good time to install new faucets / shower head / etc.

Since your copper is all shot, anyway, replace with pex, its cheaper, and don't corrode. JMNO!

At this point, that is my biggest concern of all. House built on a slab (really bad idea), with plumbing buried in or under slab.
If this is causing leaks at the water heater, where else is it leaking or about to?
Only possible saving grace is the rest of it might be pvc pipe. Copper return line switches to PVC when it enters utility closet.
Not sure if I want to take a chance on a leak I can't get to. In other words, leave pump off.

It boils down to this:
Flowing water erodes metal pipe.
Anything that affects smooth flow(burrs,bends, tees, etc.) causes turbulence. Turbulence accelerates erosion. Doesn’t matter which side of the pump your on. To that end the will relate a story. Several years ago as service plumber I was called out to a single story motel with 60 rooms. As can imagine that is a long way for hot water to travel from mechanical room to end unit. In the span of a week was called five times to repair a leak in the recirc line. Each time a different location in the same run. It was a straight run. Point is, it just wears out the pipe in relatively short period of time.

On a hunch, I looked and I have my description backwards. What you are looking at on the top of the pump is the return line. Verified that by turning pump on, opened isolation valves and got cold water. You could feel the flow and lines were vibrating......so moving a LOT of water!
Return water then flows through pump, into bottom of the tank through drain outlet......and water to faucets leaves top of tank. That way any flow to faucets is not interrupted as cold makeup water enters to replace it.
Not sure what that does to the high flow cavitation theory.

The data plate shows amp/watt rating. The screwdriver slot changes the route through the windings. This controls motor speed vs closing a valve

their site says it's 'discontinued'.....but is a 3 speed pump though HOW to change baffles me( no documentation). sad thing is I think there's one in the garage 'somewhere'... I agree though a new 'smart' pump, low flow and one that learns your pattern would be better. heck my Well pump is only rated for maybe 6 GPM...... every dang 'head' is maybe 2.5 gpm, kitchn faucet SUX.... try filling a pot......zzzzzzzzzzzzzzzzzzzzz...
