"Hired Pohlman to evaluate two natural gas tank water heaters in our home, one of which was unoperational. They suggested combi-boiler for our home in lieu of two tank water heaters. They did a great job and we are very pleased. Customer service is top notch, and I highly recommend Pohlman Plumbing."

"This was not an emergency repair, we were fortunate to be able to schedule the replacement about a week in advance. Heil sent an estimator to look at the space and make a recommendation. We originally wanted a Hybrid system but they advised against it given the space and need to collect/vent moisture. We selected a 75 gallon electric water heater. On the scheduled day, They were on time, removed the old water hearter and installed the new one - professional and courteous the whole time. Unfortunately, the new heater leaked the same day. They returned and made a temporary patch until they could return the next day with a replacement part. They returned, replaced the part and after they left we found that the tank leaked again in another place. They returned the next day and before we could insist that we wanted a different tank (clearly an out of the box failure on this one) they said they would replace the tank which they did. Our first, second and third experiences with Heil were all great with customer service and technical expertise. The inconvenience of multiple extra days without hot water and having to be there for four visits was unexpected and unfortunate however Heil responded correctly and made it right. You can get the measure of a company not only when things go right but also how they respond when things go wrong. We would use them again."

"The actual replacement was pretty straight forward, but because the codes have changed for normal W/H replacements in our area, which requires an expansion tank and also the new w/h's are now somewhat taller than prior models, they had to do some modifications to the venting. But they handled it professionally, and did exceptionally nice work. Its good to see people take pride in the work they perform. I would definitely call them again when/if the need is required."

Septic Tanks FAQs, answered by experts

It is not normal to smell your septic outside and indicates a problem such as an unsealed manhole or access lid, a clogged septic line, a faulty vent stack, or the need for a septic tank pumping. If sewage is leaking from your septic system, it can be hazardous to you, your family, pets, and the surrounding environment. You can troubleshoot the issue yourself, or contact a septic tank pro who can resolve the issue quickly.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

You can put yogurt in your septic tank, but it will not increase the bacteria in your septic tank. In other words, it won't harm your tank, but it won't get rid of a septic smell or boost the performance of your septic system. While yogurt contains helpful bacteria, you would need to buy an extraordinary amount of yogurt to make any difference. Adding yogurt is not a helpful or cost-effective strategy.

Signs that your well is dry include a decrease in water pressure, strange odors coming from faucets, cloudy, bubbly, or discolored water, and water that’s warmer than normal. Signs that your well pump is bad are similar, but you may also notice higher-than-average electric bills, strange clicking sounds, and faucets that spit or sputter.

To prevent septic tank problems, save on repair costs, and keep your home running smoothly, it's essential to perform regular maintenance. Have your septic system inspected by a professional every one to three years, or annually if possible, to spot potential issues before they develop. You should also have your tank pumped every three to five years, or more frequently if recommended by a professional based on your household's usage. Additionally, be mindful of what goes into your system. Avoid flushing items like paper towels, wet wipes, and feminine hygiene products. Do not dispose of other inappropriate substances, and try to avoid excessive water usage at a single time.
