Recently I told you about the American Plumber, asked him 10 questions and published his answers in an article on this channel. As I understand it, this format of the story really liked the readers. Which I am very happy about. In addition, I want to continue to talk about people associated with plumbing engineering. About the specialists who provide us with a comfortable stay in houses and apartments.
Today we will talk about a person who has worked with water supply, heating and sewerage systems for a long time. At the moment he works as an Engineer of the Service Center in St. Vologda. So, get acquainted: Anton Vasilievich Polin. I asked him rather slippery questions about pumping equipment, so as not to stretch the article from the answers, I highlighted important information and I will retell you, I am sure it will be interesting!
1) How did you become a service center engineer?
He started his activity in 2005, with his partner, they made a mess of apartments, changed old steel pipes for polypropylene. Little by little I moved from apartments to private houses. But the water supply and heating systems in private houses are more complicated than in apartments. I had to communicate with experts in this field. She is constantly learning and educating herself. In 2018, he began working in a large company, where he had already undergone formal training. They did not just study any laws of hydraulics, but disassemble the pumping equipment to the cogs. We were told complete (hidden) information on the repair and maintenance of equipment. You can tell secrets that you cannot find out about on the Internet.
2) What companies do you officially serve?
We officially serve companies such as Grundfos, Wilo, Gilex, Waterstry, Speroni, Jemix by pumps. Mixers: Lemark, Rosinka. And pipeline fittings DENDOR.
3) What is the average salary of specialists in your profile, when repairing equipment
The question is very interesting, it all depends on the workload. Out of season, with low workload, if you just sit in the workshop diagnosing and repairing equipment, you can earn from 10,000 rubles. If you strain and go to places and work like a bee, you can earn ... (from the author of the channel: "The legs feed the wolf")
4) How not to burn a borehole pump, a couple of tips
The most important thing when buying special equipment is to have a passport for the well, it indicates the parameters of the "well" for them and the equipment is selected. In addition, you should thoroughly study the instructions, in which you can glean important and useful information. You can not spare money to protect the pump, namely dry-running relay, voltage stabilizer and soft starter. The approximate cost of protection, together, is about 10 rubles. Plus a 20-ka pump. Good protection pays off by avoiding borehole pump breakdowns.
5) What needs to be done so that fecal pumps serve for a long time, do not break
Don't include it... Joke. And the advice is as follows: Do not narrow the discharge pipe, reducing the diameter by half, the flow resistance increases thirty-two times... Reduced engine cooling due to less fluid flow. As a result, we have lower performance and, as a result, overheating. With rare use, when pumping out septic tanks, let's say twice a year, after work it must be allowed to work in clean water in order to wash off the dirt. Ideally, remove the bottom support, get to the impeller, clean and rinse it. If this is not done, sludge, dirt, faeces deposited on the impeller can block the rotation of the pump. And when you restart it, after a certain time, it may not start. In this case, the engine will overheat and burn out.
6) Pumping stations, how to extend their life
Honestly, I hate them, I hate them. These stations are very noisy. When installed at home, the pump sounds very loud, especially when turned on at night. In this case, the household will wake up and will not say thank you. It doesn't matter if you washed your hands or went to the toilet. When the station is installed in a well, the noise will disappear. But the equipment will quickly rot from high humidity. At the same time, the efficiency of the pump is low. Due to the fact that the lion's energy of the engine goes to suction. The pump "yells" and does not give much water. But at the same time, maintenance of the pumping station is easier, since it is located in an accessible place.
And to the question of how to extend the service life: It is necessary to periodically service, namely: once every six months, check the pressure in the tank and if the diaphragm is torn, constantly check for leaks along the flange on the engine side. If there are smudges noticed in time, then there is nothing wrong with that. You just need to make repairs in a timely manner. And if you start this moment, then the station will fail, and repairs will be expensive. It is important that there is no suction in the suction line, if air is supplied, then at best such a phenomenon as "cold boiling" is possible. Due to the increased temperature of the ejector, the venturi nozzle made of plastic is deformed. There were cases of the guide vanes and the impeller jarred. But mainly because of this, the ejector suffered. Remember, the suction line must be completely sealed from the outside.
7) Is it possible to try to repair the pump yourself without special equipment and skills
Can... But will it work without special tools and skills? Everyone must do their job. This also applies to car repairs and pumping equipment repairs. If, nevertheless, you decide to start repairing, then you need a set of tools, the same vice, often without them anywhere. It is important to remember the sequence of disassembling the equipment. The main thing is not to make it worse.
8) Your rating of firms, pumping equipment in terms of price-quality ratio
This is a very difficult question, there is no definite answer to it. Industrial equipment will have the same brands. In the segment of domestic pumps, in terms of price, quality is: Gilex, very good. In the under-premium segment DAB, WILO and other Italians. Nice pumps, but something is missing. And if we consider the super premium line, then this Grundfos and... probably all. Whatever the price for them, they are always of high quality.
9) What pumping equipment do not recommend for purchase
Incomprehensible pumps, with similar names to well-known brands, run from them like fire. Unknown brands of pumps, in the absence of services for the selected equipment in your city. Check with the seller for this question. Do not take the cheapest, they often have a winding not made of copper, but aluminum. And we have seen this in our practice. Some cheap manufacturers use oil seals instead of mechanical seals... and this is in the 21st century.
10) Where is the best place to buy equipment, on the Internet or in a real store?
If you have independently studied the question of which pump you need, then you can order it on the Internet without any problems. It will cost you less, in addition to this, you will not be shoved overly powerful and expensive equipment in a real store. But it is worth noting that before buying in the online store, you should find out if there is a service center under the brand of the pump you are buying in your city in case of a breakdown. If a breakdown occurs during the warranty period, then the dispatch will be at your expense and repair for up to 40 days.
11) As specialists, you need a completed warranty card, or a check is enough, as suggested in the store
A warranty card is required, completed upon purchase and with a receipt. If there is only a check, then you will have to waste your time. Return to the store that made the sale, it will be filled there. And only after that he will apply for a guarantee to the SC.
12) What annoys you about customers who bring equipment under warranty.
- The fact that no one reads the instructions. DOT!
13) Your wishes and advice to the readers of the channel "Did you call plumbing?"
Read the instructions for the pumping equipment, thoughtfully take your time, tick the boxes in important places. Something did not understand, re-read. If it is not at all clear, refer to the manufacturer's website, and everything is complicated there? Contact the service center, no one will send you to the forest, will not be considered fools. At the same time, 10 minutes of time spent reading the instructions can save you from expensive repairs.
Let all your equipment work properly and rarely break down. So that everything is fine with you.
