DC5P-100/500 Spin Down Sediment Filter

A must have for every well, solid brass construction, very sturdy feeling for sure. Valves and handles feel like quality. Filters are super easy to change if you install shut off valves on both sides. Super fine filter worked great but slowed water fall after a few months. It’s an ultra fine filter so I expected that. I replaced it with the larger micron one included. Buy it.

Great pre filter for my R/O unit easy to clean and install

Great job filtering and releasing dirt. I recommend it to add with express water standard whole house filtration.

Great design on these. Given the tiny overall size of the unit, the flush feature is an absolute must! It is built completely with high-quality components, and it comes with everything needed to plumb it directly into an existing line, so I think it is a great value. However, the little tablets it has for reducing scale are wicked nasty from a down-stream water quality perspective, so I had to ditch those right off the bat. In addition, they are extremely high maintenance in terms of trying to maintain water flow through the screen when you have any degree of debris that is in the water. The small stuff actually sticks into the screen, and these particles do not flush out with the valve, so I find that I need to remove the housing every week or so to blow it out from the inside in order to maintain decent flow. Generally, I flush it daily and blow it out every 7-10 days. Having well water that consistently supplies some fine silt into the water, I may be further down the particulate spectrum than those whose particulates originate from the piping itself (as is the case with, say, city water supplies), but I find this frequency annoying. It's way better than replacing a disposable filter every 2-3 weeks, though! I installed mine just upstream of my disposable filter, and I only need to replace it every three months now (strictly based on volume of water filtered versus a lack of flow through it). In that sense, I'm pretty sure it has already paid for itself after only three or four months of use. If the manufacturer provided a backflow loop with it (or recommended installing one), I think that would go a long way to alleviating the pitfalls of the tiny size of the unit. Doing so would allow the flush process to blow the water out from the *inside* of the filter screen instead of the outside the screen. In this way, it is likely one could go years without ever having to pull the housing off for cleaning or replacing filtration components.

I installed this pre-filter ahead of my whole-house system (where replacement filters run about $200 each), and it’s been an absolute game-changer. Here’s why: Extends Filter Life: Captures sediment and debris before it ever reaches the main filter, so I’m no longer replacing those expensive cartridges every few months. Built-Tough Construction: Heavy-duty housing with leak-proof seals—no pressure loss, no worries. Easy Installation & Maintenance: Clamps on quickly to existing plumbing and the cartridge swaps out in seconds. Immediate ROI: Paid for itself by preserving one expensive filter already—best investment I made in my water system. Room for Improvement: None—this unit delivers exactly what it promises. I have zero suggestions!

Throughout the installation process I found this pre-filter to be of decent quality. I ordered a 3/4 in and I received a pre-filter that had 1 in MNPT connectors on the housing and it included a screw-on coupling type connector that turned the 1 in into a 3/4-in MNPT connection. The most puzzling part of installing using the 3/4 in coupling connectors was the lack of material to be able to tighten the couplings into the rest of the existing pipe architecture. I came to these reviews several times seeking advice from other people and I didn't see any solution but I did see that there were a few others that were confused like I was and were experiencing the same issue. So I will pass on this tidbit of information. The 3/4-in couplings can be tightened quite well by using a special wrench that goes inside the lumen of the 3/4-in connectors. Inside the lumen you'll see that there is two opposing ear like structures. I included a picture of the wrench that you'll need in order to be able to tighten these connectors with appropriate torque. I went to my local plumbing store and was introduced to this new tool as I had never used one before. I used the fork end of the pop out plug wrench and was able to adequately torque down the connectors. I hope that helps anyone else like me that was looking for a hand up. I haven't finished my system yet, if something changes my feeling about this pre-filter filter I will update my review but as of right now, I think it's a great value for the money.

An extra filter before it goes to my 3 chamber water purifier. Easy to install, no leaks. Excellent quality. It function very well. Seems great 3 months later no need to clean filter yet

Excellent device is exactly what I needed for city water to keep my drip system operating at top efficiency. I did not use their 3/4” adapters I used a series of 3/4” brass npt to npt adapters or npt to ght adapters and connected everything together with teflon tape and pipe dope over that. No leaks! Now when I see grit I can just flush the valve. This circuit runs to 4 wine barrels with golden goddess bamboo and drip hoses. Works as imagined and does not clog. The system also has a pressure reducing valve and a RAINPOINT WiFi controlled water valve so everything is controlled by an app that I can adjust on my phone.
