## Description

Great Product

Review: Worked perfectly - Had to replace the OEM strainer in our RV, this fit perfectly and is still working fine years later.
Review: Complete install guide. Excellent product. Necessary RV upgrade (plus accumulator) - Put this strainer near your inlet to your Shurflo or other brand pump. I DO NOT recommend threading this directly on the pump head, because the pump head is soft thermoplastic, and you are better off following the directions below. Also get an accumulator (Shurflo part, about $44). Together, they make a solid, easy and I think, necessary, addition to your RV plumbing. My suggestions: if your pump is next to your tank, and you have a system that permits this, and has a floor-level outlet on the tank, here is a step-by-step: First phase: Re-plumb from the floor-level outlet of your tank, because it usually has an internal strainer that backs-up garbage in the tank. With the tank empty, look for and REMOVE THE EXISTING TANK STRAINER. It will usually easily come out of the threaded hole your plumbing leaves the tank from. These break and are, for obvious reasons, difficult to clean, backing up an organic sludge, even if you have drained it previously. Do new plumbing. Assuming you have a floor-level tank outlet, 1/2" female thread: Prepare your new plumbing, by building with half of a galvanized union joint, to the end of a 10" plastic nipple, with teflon tape. This leaves an easy joint to hook up the rest of your plumbing later. Run the other end of the plastic nipple into the tank, again, removing any existing tank strainer first. Mount wood to the floor if needed to make the nipple run completely perpendicular to the tank outlet, no cross threading. Use a 1/2" o-ring to help seal the nipple into the tank. Do not overtighten! It's a lot less force than you use with your downstream plumbing fittings. Literally, hand-tight. I found mine crossthreaded easily if overtightened. In my case, I also had a tank on carpet, so I needed wood to level the nipple. Yes, carpeted in the tank area. Use heavy pipe straps (electrical section of hw store) to stabilize the nipple down to the floor. Second phase: Mate the other end of the galvanized union to a 3 to 4" metal nipple with teflon tape, then the other end of the nipple to a galvanized corner T. On mine, shooting off at a 90deg angle, was almost perfect to meet up with the drain hole. It also goes straight up, where you will install another union fitting and an elbow, and the strainer. Finish the floor-level corner T exit with another metal 5" nipple, brass valve, and exit pipe to drain to the outside. Don't add these phase 2 component to the first phase plumbing yet. Just kit everything together, being careful not to disturb the initial 1/2 plastic nipple and union. Although P1 should be mounted solidly down. From the riser part of the corner T, install a short metal nipple and now, a plastic union. I think these are nylon or tough plastic, and used in irrigation. Now you should be able to install, and mount, the phase 2 elbow T/drain, with its fittings, to the floor, solidly, again with wood and straps on the wood if needed to bring it to tank level, and connect it to the first union, the galvanized one. Using a galvanized metal union for the first, has better clearance than the larger plastic kind. Plus, except for the plastic nipple leaving the tank, you want this corner and it's connected pieces, to be galvanized (metal), as it is more rigid. Floor should not flex over the short distance. Use straps to mount Phase 2 to the floor, solidly, both before the elbow, and after to the drain. The half of a plastic union should be sticking straight up. Phase 3 Off the plastic union second part, attach a SCH40 elbow w TT. Use one with a male threaded end, and a female threaded end. Into the female end, screw the Shurflo 255-313 Strainer w TT. This way, there should be about 2-3 inches of clearance between the bottom of the clear strainer basket, and the floor. This makes it easy to remove the strainer basket without having to completely empty the tank. You should have to have about a half-full tank to maintenance the strainer. Add a short plastic nipple to the strainer outlet w TT. Add Phase 3 plumbing to the existing plumbing, being careful to only tighten the plastic union joint, and not stress the Phase 2 plumbing. Use a flexible line (ACE has these for about 5-6$, in 12-16" lengths) 1/2" FIP to 1/2" FIP, connect to the strainer outlet to the pump head. The pump can be sitting on the floor, on it's rubber feet. No telfon tape needed on the flexible hose, as it has rubber cone washers embedded in it, and not a ton of torque (BE CAREFUL with the soft pump head). These very flexible lines also greatly reduce vibration into the plumbing. I found that the Shurflo PUMP HEAD especially, is a crappy kind of thermoplastic. VERY SOFT. Much softer than the Twist-on Strainer. So in order to access the strainer basket and reduce stress on the pump fittings, do not screw strainer directly onto the pump. Outlet of the pump, you are going to use another 1/2 FIP to 1/2 FIP. First, build your accumulator: use another short plastic nipple, on one side of a Shurflo accumulator, the side facing towards the pump if you mounted the accumulator. Screw the nipple into the accumulator with teflon tape first, then mount the accumulator, THEN lastly use the 1/2" to 1/2" flexible hose to hook pump to accumulator. This allows you to easily move the pump around to an ideal location, and also, disconnect when changing things like the pump head pressure switch (when it fails). After the accumulator, continue your regular plumbing. Mount the accumulator with the shrader valve pointing up, if you can, to make sure that water completely drains when winterizing. I had the model with the metal bracket, not the one with the rubber feet.

## Questions & Answers

**Q: how would this hook up to a washing machine inlet line? (i.e. what type of adapters would be needed for both sides..)**
A: This Shurflo item is great for RV water delivery services, but totally inadaquate for washing machine service.   Go to hardware store or Home Depot and buy a general water filter housing that takes 9 inch spun wound filters.   If you get sand or grit into your RV water tank, it will settle to the bottom.  The Shurflo strainer wouldn't see much of this coming through for long time, unless the fresh water tank is stirred up alot.  When you lose your home water supply, then a lot of sediment in the utility "main" lines will be churned up on startup.  Someone, somewhere has to flush these lines to remove the sediment, OR it just gets moved down the line and someone else suffers this problem.  If your home is drawing water to the washing machine at the time these lines are activated, or until the sediment finds a resting place along the pipe route, an inline general 9 inch filter will keep dirty water from ruining your clothes inside the washing machine.  In my subdivision, this has happened many times and I have two filters in series to stop ruining my clothes.  I use the metal flexible washing machine hoses with 3/4" female connectors on each end.  I buy 3/4" male hose connectors installed in each end of the filter housing.  This setup will be more adaquate for your washing machine than the Shurflo strainer.

**Q: How do I get a city connection regulator so the water flow is not so pressurized. Marian**
A: Camco sells pressure limiters made of brass for less than $10. They are fitted for garden hose connectors. There's a few other companies that make them too. Pressure is set to about 30 lbs. I get mine at Walmart, but you can get them in RV parts places. I use one, and a Camco 'blue' water filter, and a Camco right-angle adapter to reduce stress on the fittings. A word of advice, based on my experiences, put the filter in-line before the pressure limiter. They have a small orifice and sand and dirt will ruin them.

**Q: Is there an adapter available to allow this filter to connect to the end of a standard garden hose.  I plan to use it to pump water out of a lake.**
A: I would not recommend using this in a line pumping lake water. If there is much  debris in the water you will be cleaning it all of the time. I would suggest a bigger unit.

**Q: does it come in larger pipe connections ?**
A: We do not carry this item in any other sizes.
